The increased levels of erythrocytes causes increased blood viscosity and uneven blood flow through the lungs (V/Q mismatch). However, CMS is also considered an adaptation of pulmonary and heart disease to life under chronic hypoxia at altitude.
Despite this performance, he did not perform well in the altitude of the Kenyan Olympic trials and finished outside of the top five.Mutuota, Mutwiri (23 June 2012). Rudisha runs 1:42.12 at altitude – Kenyan Olympic Trials . IAAF. Retrieved on 2012-06-24.

The M-87 had the same horsepower rating at takeoff as the M-86, but produced more power at higher altitudes. The M-87B further increased power at altitude and was introduced in 1939–40. These aircraft were known as the DB-3B as part of the second stage of the upgrade program.
Fig. 4 Atmospheric pressure Atmospheric pressure decreases with the height above sea level (altitude) and since the alveoli are open to the outside air through the open airways, the pressure in the lungs also decreases at the same rate with altitude. At altitude, a pressure differential is still required to drive air into and out of the lungs as it is at sea level. The mechanism for breathing at altitude is essentially identical to breathing at sea level but with the following differences: The atmospheric pressure decreases exponentially with altitude, roughly halving with every rise in altitude. The composition of atmospheric air is, however, almost constant below 80 km, as a result of the continuous mixing effect of the weather.

In jamming-free conditions, using just two transmitters, the Type 85 was horizon-limited against a 1 m² target, giving it a nominal range of , since the receivers were range gated to 3 ms (300 "Radar Miles"), with the radar horizon at altitude. This represented a great improvement over the already excellent Type 80's approximate range.
It was tied at altitude by Ter-Ovanesyan in 1967. In 1967, he lost the national title to Jerry Proctor. When rival Bob Beamon was suspended from the University of Texas at El Paso, for refusing to compete against Brigham Young University, alleging it had racist policies, Boston began to coach him unofficially.Bob Beamon Biography at thehistorymakers.
Airport buildings, taxiways and runways occupy part of the local ecosystem. Most of aircraft movement however is in air at altitude and so is away from direct interaction with sensitive natural surface features or human detection. This is different from roads, railways and canals, which are very significant in use of land and the dividing of ecological zones.
The anti-stall devices activated while they were at altitude, but the pilots repeatedly overrode the automatic nose-down that would increase speed to prevent stall. After four overrides, both engines experienced flameout and shut down. The plane then stalled, and the pilots recovered from the stall at FL380 or while still having no engine thrust.

Comet 1 at Heathrow in 1953 BOAC Comet 4 in 1963 In May 1952 BOAC was the first airline to introduce a passenger jet into airline service. This was the de Havilland Comet which flew via Nairobi to Johannesburg and via the Far East to Tokyo. All Comet 1 aircraft were grounded in April 1954 after four Comets crashed, the second last being a BOAC aircraft at altitude. Examination of the wreckage recovered from the Mediterranean sea-bed and observation of a sample fuselage in a pressurisation test-tank at Farnborough revealed that the repeated pressurisation / depressurisation cycles of airline operation could cause fatigue cracks in the thin aluminium alloy skin of the Comet leading to the skins ripping away explosively at altitude and disintegration of the aircraft.
Launch at altitude allows a larger, more efficient, yet cheaper first-stage nozzle. Its expansion ratio can be designed for low ambient air pressures, without risking flow separation and flight instability during low- altitude flight. The extra diameter of the high-altitude nozzle would be difficult to gimbal. But with reduced crosswinds, the fins can provide sufficient first-stage steering.

The lowest part of the municipality in the valley of Mesta river are turned to arable or inhabited areas. At altitude of 600–700 meters the slopes are covered with oak forests. Beech forests can be seen from 900 to 1800 meters especially under peak Orelek. Wide areas in Pirin are covered with different coniferous trees from 1500 up to 2200 meters altitude.
With a vacuum system, the maximum pressure differential is atmospheric pressure ( at sea level, less at altitude). Therefore, an air brake system can use a much smaller brake cylinder than a vacuum system to generate the same braking force. This advantage of air brakes increases at high altitude, e.g. Peru and Switzerland where today vacuum brakes are used by secondary railways.

One can never see directly freezing rain, rain or snow on weather radars, Doppler or conventional.
The volcano has been affected by glaciation. Glacial U-shaped valleys are found on the northern and western flanks, giving the volcano some angular patterns. One valley with glacial features and a subglacial river channel at altitude is found on the northern flank. It extends down to the valley north of Aguas Calientes and intersects the youngest lavas of the volcano.
Ocós is a municipality in the San Marcos Department of Guatemala. It is situated on the Pacific Ocean coast, very close to the border with Mexico at altitude and two big rivers: the Suchiate and the Naranjo rivers. On 23 January 2014, it lost about 2/3 of its territory when La Blanca was named the thirtieth San Marcos Department municipality.
Training masks allow users to actively work on their respiratory muscle fitness. Originally designed to simulate training at altitude, the concept failed to deliver in multiple research trials. Training in hypoxic (low oxygen) environments increases red blood cell mass and improves oxygen transport, giving athletes a measurable performance boost when competing at sea level.Gore, C.J., Clark, S.A., Saunders, P.U. (2007).

For instance, consider a bomber at altitude dropping a stick of AN-M65 500 lb general-purpose bombs. These bombs will take approximately 37 seconds to reach the ground. In a wind the bomb will move about due to the wind's effect on the aircraft's ground speed. In comparison, the effect of the wind after leaving the aircraft would be only .
Scott Reservoir covers with an average depth of , and lies at altitude. It is usually somewhat turbid, which helps control algae blooms and aquatic weeds. This, coupled with a perennial stream flowing in, creates a stable water quality condition. The lake is stocked with catchable-sized rainbow trout in spring, early summer and fall, and it is occasionally stocked with channel catfish.
When he tried to pull away from the DH.9 at altitude, his controls came loose in his hand. His attempt to use a parachute failed because it required the use of both hands. His Fokker crashed into a house in Ablaincourt with such force that its engine fell into the cellar. German infantrymen plucked him from the rubble and rushed him to hospital.

It is found in still, shallow water in well vegetated ditches, ponds, bogs and lakes.
The aircraft made its first hover on 16 November 1954. This was performed with the aircraft raised on a platform to avoid the reingestion of its exhaust gases. Wheeled landing gear - from a Cessna - was added to the aircraft, which went on to make horizontal flights in 1955. It proved able to make partial conversions at altitude, however it lacked sufficient engine thrust to complete the transition.
The first prototype (#54-1619) was fitted with temporary landing gear and made its first horizontal flight on December 10, 1955. Later, it made full horizontal to vertical attitude conversions and back again at altitude. The first prototype then had the landing gear replaced with a tail-mounted framework that held it in a vertical attitude on the ground. Using this rig, hooking practice was conducted.

The first of the two game test series was played at altitude in Bloemfontein and South Africa eventually won the match 31–17, despite the scores being level at 11-all at half time. The second match was played in the Newlands Stadium in Cape Town, and was a closer affair. However, South Africa maintained their unbeaten record against Ireland on home soil by winning 26–17.
In 1939, Hispano started prototype deliveries of the new Hispano-Suiza 12Z engine of . One was fitted to a modified M.S.410 to create the M.S.450, giving dramatic improvements in performance, especially at altitude. However the engine did not enter production before France fell, and the similarly modified Dewoitine D.520 (the D.523) was considered a better design for the engine anyway.
Currently, a high-altitude airship project is planned to survey hundreds of kilometres as their operation radius, often much farther than the normal engagement range of a military aeroplane. For example, a radar mounted on a vessel platform high has radio horizon at range, while a radar at altitude has radio horizon at range. This is significantly important for detecting low-flying cruise missiles or fighter-bombers.

Guidance is provided by an intertial navigation system with mid-course updates from LRTR and active radar homing in the terminal phase. PAD has capability to engage the class of ballistic missiles at a speed of Mach 5. PAD is fast enough to hit medium-range ballistic missiles and intermediate-range ballistic missiles.
In 2013 the commune built two certified passive buildings (heating needs are less than 15 kilowatts m²/year) with four housing units at 1200 m altitude.Michel Simon, Passive houses at altitude, La Marseillaise, 14 July 2013, p. 10 The passive concept is the most advanced in the world and is the only one which can dispense with conventional heating. The heating power is provided by 10w/m2 of fresh air (ventilation).
Additionally, it was able to attack aircraft flying at altitude, a limit selected to allow tracking cameras to see the target. These tests demonstrated there was no practical lower altitude limit to the technique. The downside to the inverse monopulse seeker is twofold. For one, it requires the radar on the launch platform to have monopulse encoding, or there will be no directional signal for the seeker to process.
The flight, operating on the Calcutta-Imphal route, crashed into Thangjing hills, about south-west of the Imphal airport. The aircraft had started the short flight from Calcutta around 12:00 pm and it began a descent into Imphal airport at around 12:41 pm. Visibility at that time was . Imphal airport lost contact with the aircraft just after 12:45, at altitude on the Instrument Landing System.
Without the prototype's supercharger, performance at altitude was appreciably reduced although the aircraft had a greater endurance than contemporary single-seat pursuits. Despite the gull-wing, pilots had poor visibility over the nose which contributed to service pilots having a propensity to nose-over on landing. All Berliner-Joyce PB-1s were withdrawn from active service in 1934, although a small number of aircraft continued in second line duties until 1940.
Michael Duane Miller (born December 29, 1959) is a retired track and field sprinter and American football wide receiver. Representing the United States, he is best known for setting the 1982 world's best year performance in the men's 200 metres. He did so at altitude on June 2, 1982 at a meet in Provo, Utah, clocking 20.15. Miller was an All-American track athlete at the University of Tennessee.
Garrapata Road connects into Garrapata State Park and the other, over Long Ridge, connects to the Big Sur Land Trust's Glen Deven Ranch. Both are only used as fire emergency routes. The road ends after at Bottchers Gap, at altitude, the site of former homesteader John Bottcher's cabin in 1885–90. It is currently a primitive campsite and trail head into the Ventana Wilderness and the Los Padres National Forest.
After leaving the Lake District, Dalton returned annually to spend his holidays studying meteorology, something which involved a lot of hill-walking. Until the advent of aeroplanes and weather balloons, the only way to make measurements of temperature and humidity at altitude was to climb a mountain. Dalton estimated the height using a barometer. The Ordnance Survey did not publish maps for the Lake District until the 1860s.
Bob Beamon's record in the long jump held for almost 23 years and has only been beaten once without altitude or wind assistance. Many of the other records set at Mexico City were later surpassed by marks set at altitude. Athletes can also take advantage of altitude acclimatization to increase their performance. The same changes that help the body cope with high altitude increase performance back at sea level.
A porter, also called a bearer, is a person who carries objects or cargo for others. The range of services conducted by porters is extensive, from shuttling luggage aboard a train (a railroad porter) to bearing heavy burdens at altitude in inclement weather on multi-month mountaineering expeditions. They can carry items on their backs (backpack) or on their heads. The word "porter" derives from the Latin portare (to carry).
Moreover, the pilot also had to wear a high altitude suit as he might have been required to bail out at altitude. The Welkin required a sophisticated electrical system. This was to minimise the number of seals and points of entry in the cockpit for the controls and instrumentation. It took an electrician experienced in the features of the Welkin four hours to undertake a pre-flight check of this system.
The sixth All-Africa Games were held in September 1995 in Harare, Zimbabwe. As the track is at an altitude of 1473 metres all performances are considered to be set at altitude, this is believed to assist events up to 400 metres and in the long jump and triple jump. However, for events beyond 800 metres the thinner air is believed to have a detrimental effect on performances.
T Cross Ranch is a dude ranch in Fremont County, Wyoming. The ranch is located at altitude in Shoshone National Forest, from Dubois and from the Washakie Wilderness. Apart from a cabin built by the site's original homesteader, the contributing buildings of the ranch date between 1916 and 1946. The ranch was established in 1918 by German immigrant Henry Seipt when he established his homestead and called it The Hermitage.

It culminates at altitude of at the level of the jebel Fellaoucene. The Trara Mountains are a coastal range in the western extension of the Tell Atlas mountains. It represents, in the Tell Oranais, a mountainous block whose access is very difficult.
Nine Myanmar Navy ships, and three military aircraft and helicopters were sent to assist in the search. On 7 June, debris from the aircraft was reported to have been found off Dawei by a Myanmar Navy ship. On 8 June, it was reported that 29 bodies had been found. The wreckage was scattered over a wide area, indicating that the aircraft might have disintegrated in flight at altitude.
Stone initiated his research career in high-altitude physiology under the direction of Ross McFarland, at the Harvard School of Public Health. Working with his associate Dr. Spengler, Stone searched for a high-altitude environment in a city and published the first paper on carbon monoxide in hockey rinks noting the effect of carbon monoxide on the hockey players' visual acuity was similar to that of hypoxia at altitude.
Junker's design, the EF 126, was of similar layout to the V-1, with the single Argus 109-044, rated at , mounted above the aft fuselage and fin. The fuselage was of metal construction while the wings were wooden. A retractable nosewheel undercarriage was to be fitted. As the pulse-jets power would reduce at altitude, the aircraft was intended for low-altitude use, and had a secondary ground attack role.
Potassium–argon dating and argon–argon dating performed on rocks from the Chao I stage have indicated an average age of 423,000 ± 100,000 years. However, anomalous chemical compositions of the dated rocks suggest that they may overestimate the true age of the volcanics. Such alteration may be the result of the inclusion of xenocrysts or K leaching. A glacial moraine system lies on Cerro del León at altitude.
The standard Lares trek route is the shortest () and easiest route, and only crosses one high pass. The route takes three days to trek and one day on top to visit Machu Picchu. Trekkers depart Cusco () early on the first day, often around 6am, and drive for several hours to Calca, a small town at altitude. From Calca, trekkers are driven a further three hours north until they arrive at Lares.
The aircraft was also under-equipped, provided with a mediocre radio set (powered by batteries that were prone to freeze at altitude) and lacking any armour protection. The experiences of the early G.50s over Britain soon showed their inadequacies in combat. Their operations were considered to be next to useless during the campaign, in part because they were too short-ranged and stationed too far from enemy territory.
When the slats were activated with such force that they were ripped off the wings, the slats were wired shut.James 2006, p. 65. As the performance of the Peregrine engines fell off at altitude, the Whirlwind was most often used in ground-attack missions over France, attacking German airfields, marshalling yards, and railway traffic. The Whirlwind was used to particularly good effect as a gun platform for destroying locomotives.
At altitude, the highest elevation in Bangladesh is Saka Haphong at Mowdok range, in the southeastern part of the hills. Highly elevated peaks of this area can also be called mountains as hills above with a distinct peak are referred as mountains. Seventy-five such mountains have been identified and mapped in the Hill Tracts.Mountains of Bangladesh (Map) 2015, Fertile valleys lie between the hill lines, which generally run north–south.
At altitude the town offers "eternal spring" with annual temperatures ranging from 50–80 degrees F. The dry season runs from November through June/July (called "summer" locally) and the rainy season runs the other six months ("winter"). The area is free of malaria due to its elevation. The area's elevation ranges from along the lake to at the summit of Volcán Tolimán. Volcán Tolimán is just west of town.
Video of singing bird The crested lark is a songbird, and has a liquid, warbling song described onomatopoeically as a ' or a '. It sings in flight from high in the sky, at roughly above the ground. The related Eurasian skylark exhibits similar behaviour but also sings during its ascent, whereas the crested lark sings either at altitude or on the ground. Their flight pattern is an example of undulatory locomotion.
The height ascended was 19,411 feet, and the total computed altitude of the mountain 22,000 feet. A small collection of geological specimens, made by Gerard in Chinese Tartary during this journey between latitude 31° 30′and 32° 30′ N. and longitude 77°–79° E., at altitude 19,000 feet, and resembling the fossils of the oolite in Europe, was exhibited at the Geological Society of London after his death.
In 2010, Donald Zarda was fired from his skydiving job at Altitude Express. He had told a customer he was gay to make her more comfortable with being strapped together. The woman's boyfriend later complained to the company that Zarda had inappropriately touched her, and Zarda was fired as a result. In October 2010, the press first reported that Zarda had brought his firing to court and was suing Altitude Express.
In the final she beat the favourite, world record holder Tatyana Schelkanova of the USSR and Poland's Irena Kirszenstein. Her first jump of 6.59m was a British record. However, in the fifth round, on a wet runway with a headwind of 1.6 metres a second, she broke the world record, leaping 6.76m to take gold. Her record lasted four years until it was broken at altitude by Viorica Viscopoleanu in the subsequent Olympics.
Since time on the track was scarce, the Italian team did not want to give Ritter much track time. On the day before the Olympics started, Ritter was allowed to ride in the morning, and he beat the hour record. He was the first rider to take the record at altitude since Willie Hamilton in 1898. He covered 48.653 km and it took four years and Eddy Merckx to beat it (49.431 km in 1972).
The circular organisation around the cacique resembled the organisation of the Muisca villages, where the central bohío belonged to the ruler of the settlement. In 1885 Muisca scholar Liborio Zerda described a mummy of a young girl, found in a cave on the Toquilla paramo, at altitude within the municipality of Aquitania. The mummy was wrapped in cotton mantles and decorated with golden objects. The body was eternalised in a squatting position.
The main character is Mark, a mountain guide. Most of the characters are engaging animals, including Leo the Mountain Dog and three little Marmot Mountaineers. At the end of the story, an instructional section explains more about some of the phenomena encountered along the way. In the first book, Mark the Mountain Guide, this includes child-friendly explanations of what causes an avalanche, how mountains are formed and why stars are so bright at altitude.
Picea omorika, common name Serbian spruce (, , ), is a species of coniferous tree endemic to the Drina River valley in western Serbia, and eastern Bosnia and Herzegovina, with a total range of only about 60 ha, at altitude.

The TAWS alarm "Pull up!" was first sounded at altitude and then repeated several times before the crash. It was first sounded 18 seconds before hitting the tree and the crew attempted to abort landing 13 seconds later. Due to geographical relief the aircraft was actually below the runway at the time of the first impact. On 26 May 2010, it was reported that pilot error had been identified as the reason for the crash.
Grishk (), also spelled Girishk or Gereshk, is a town in Grishk District in Helmand province on the Helmand River in Afghanistan, some northwest of Kandahar, at altitude. Upstream lies the Kajaki Dam which diverts water to the Boghra Irrigation Canal, an essential infrastructure for the region's crops. Grishk Dam is also nearby. Grishk was originally built around a fort on the east bank of the river but was later rebuilt on the west.
Another obvious change was the replacement of the Wright J65 turbojets with Pratt & Whitney TF33-P-11 turbofan engines. The TF33s gave the aircraft more than double the thrust of the B model. The RB-57F was also fitted with two detachable Pratt & Whitney J60-P-9 turbojets mounted in pods attached to the wings outboard of the main engines. These auxiliary engines were air-started and only for use at altitude in flight.
The IIG was installed on the prototype of Aérospatiale's Fouga 90 jet trainer (a development of the Fouga Magister). Using this medium- bypass version of the Astafan instead of the Turbomeca Marboré, the 90 had twice the range of the Magister (with a similar fuel load). Installed in the Fouga 90, and operating at its maximum thrust of , the IIG's specific fuel consumption was . At altitude and Mach 0.5, specific fuel consumption was .
This refers specifically to hypoxic states where the arterial content of oxygen is insufficient. This can be caused by alterations in respiratory drive, such as in respiratory alkalosis, physiological or pathological shunting of blood, diseases interfering in lung function resulting in a ventilation-perfusion mismatch, such as a pulmonary embolus, or alterations in the partial pressure of oxygen in the environment or lung alveoli, such as may occur at altitude or when diving.
Found in Clark and Mohave Counties in the vicinity of the artificial reservoir Lake Mead, it grows on stony barren slopes at altitude. It often grows alongside the rare golden bear-claw poppy or Las Vegas bear-poppy Arctomecon californica. Both plants grow in a fragile gypsum crust on the soil, which when damaged facilitates the spread of invasive plants. Its habitat is threatened by the reservoir as well as off- road recreational vehicle use.
In that race, he was leading with about 300 Meters to go before falling victim to Mexico City's altitude and "hitting the wall". He was passed by two athletes born and trained at altitude in Kenya. The following year Young set two world records in the indoor two and three mile events with times of 8:27.2 and 13:09.8, respectively. He was featured on the March 1969 cover of Track and Field News.
The plant can go from a stand still to operational in eight minutes which allows it to meet peak energy demand. It consumes more electricity pumping than generating electricity but pumping occurs during periods of low demand with unused surplus energy available at lower costs from the electric grid. The upper reservoir, Courtright Reservoir, has a storage capacity of is at altitude of . Wishon Reservoir, the lower reservoir, has a storage capacity of .

U-2 pilot suit A pressure suit is a protective suit worn by high-altitude pilots who may fly at altitudes where the air pressure is too low for an unprotected person to survive, even breathing pure oxygen at positive pressure. Such suits may be either full-pressure (i.e. a space suit) or partial-pressure (as used by aircrew). Partial-pressure suits work by providing mechanical counter-pressure to assist breathing at altitude.
Extra power, or specific excess power, is a very basic method of determining an aircraft's flight envelope. It is easily calculated, but as a downside does not tell very much about the actual performance of the aircraft at different altitudes. Choosing any particular set of parameters will generate the needed power for a particular aircraft for those conditions. For instance a Cessna 150 at altitude and speed needs about to fly straight and level.
A "rotating loop" "LadderMill" project is designed and developed by the Dutch ex-astronaut and physicist Wubbo Ockels. As quoted from his website: > The LadderMill is the response to the challenge for exploiting the gigantic > energy source contained in the airspace up to high altitudes of 10 km. The > concept has been developed with the aim to convert wind energy at altitude > in electricity on the ground in an environmental and cost effective manner.
This bird is a species of least concern to the IUCN, with an estimated range of and between 10,000 and 100,000 wild individuals. However, there is evidence that suggests a decline in population, though it is not significant enough to cause it to be listed. This decline is due primarily to habitat destruction and poaching. Although distinctive, its habit of perching in tall trees and flying at altitude render it difficult to monitor.
KOCIS Royal Azalea (8573227639) Rhododendron schlippenbachii, the royal azalea, is a species of Rhododendron native to the Korean Peninsula and adjacent regions of Manchuria (Liaoning, Nei Mongol), Japan, and the Russian Far East. It is the dominant understory shrub in many Korean hillside forests, growing at altitude. It is a dense deciduous shrub growing to in height, but more commonly tall. The leaves are obovate, long and broad, with scattered glandular hairs.
Two MS.221 prototypes were built. The precise date of the MS.221's first flight, flown by Fronval, is not known but it was before March 1928. Despite being lighter and more powerful, it was significantly slower at altitude than its competitors, so one MS.221 prototype was re-engined with a turbo-supercharged Gnome-Rhône 9As Jupiter which could deliver full power at . The wing struts were also revised to reduce drag.
It was used as the nation's standard platform, capable of being efficiently adapted to perform all tactical mission roles. Other requirements included supersonic ability at low level, Mach 2 performance at altitude, and the ability to make short landings at low angles of attack (to avoid damaging improvised runways). The aircraft was also designed from the beginning to be easy to repair and service, even for personnel without much training.Bitzinger 1991, p. 18.

It is a polymetallic mine which significant mineral resources and ore reserves of copper with an estimated mine life of at least 20 years. Production at the mine is scheduled to start in 2015 following an 80% confirmation completion of the project on 31 Dec 2014.
A trough is the result of the movements of the air in the atmosphere. In regions where there is upward movement near the ground and divergence at altitude, there is a loss of mass. The pressure becomes lower at this point. At upper levels of the atmosphere, this occurs when there is a meeting of a mass of cold air and another hot one along a thin ribbon called a frontal baroclinic zone.
One such aircraft was tested, after these problems had been fixed, by the Flight Research Institute () and proved to be only slower than the etalon at altitude. Aircraft from both factories were evaluated in September by the Air Force Scientific Test Institute () and the problems persisted as the aircraft could only reach at a height of and had a time to altitude of 5.1 minutes to 5,000 meters.Gordon 2003, pp. 66, 69, 126.
Clancy, L.J. (1975), Aerodynamics, Table 1, Pitman Publishing London, The speed of sound is not a constant; in a gas, it increases proportionally to the square root of the absolute temperature, and since atmospheric temperature generally decreases with increasing altitude between sea level and , the speed of sound also decreases. For example, the standard atmosphere model lapses temperature to at altitude, with a corresponding speed of sound (Mach1) of , 86.7% of the sea level value.
The accident was attributed to the use of the wrong type of grease in the aileron controls; one aileron had "stuck in position, sending the aircraft out of control". The test pilot, Squadron Leader Douglas Davie, bailed out from 33,000 ft, suffering frostbite on the way down. The first prototype was fitted with the thrust W2/500 and was flown to 42,000 ft, but level speed at altitude was not attempted due to fuel shortage.
The long-stalk spiderhead can be found in Du Toitskloof, between Paarl and Worcester in the northwest to the neighbourhood of Cape Agulhas in the southeast. It grows at altitude in fynbos vegetations on sandy soils that have been formed by the weathering of acid sandstones. The flowers were observed to produce a strong sweet scent, reminiscent of jasmine, late in the afternoon. No smell has been noted earlier during daylight hours.
Aru and his personal coach Paolo Tiralongo made his training too hard, and spent too much time at altitude which meant his body was fatigued already going into the Giro d'Italia. He returned to racing at the end of July, at the Tour de Wallonie, and finished 10th overall. A week later at the Tour de Pologne, Aru finished 10th overall once again. He started the Vuelta a España as one of the main favourites.
The CT-114 Tutor is a single-engine turbojet-powered trainer aircraft. It was purpose-designed for the training role, and possesses numerous favourable qualities, including a high level of reliability and favourable operating economics. It is capable of a wide performance range, possessing a top speed at altitude of 795 kmh (429 kt) and a diving speed of 885 kmh (478 kt) against a relatively low stalling speed of 71kt.Norris 1998, p. 23.
A South African, he was an experienced pilot nearing the end of his first tour. 97 Squadron would be led by Squadron Leader John Sherwood. 97 Squadron Lancasters over the English countryside on their way to a mock target in Scotland Bomber Command crews were trained to fly on their own at altitude in trail and during the night. The crews were unfamiliar with low level flying, and they did not perform formation flying.
Frederick Manson Bailey described Ficus tryonii in 1906, from a collection at altitude on Middle Percy Island in the Whitsunday Islands off central Queensland, which is now regarded as F. obliqua. Joseph Banks and Daniel Solander collected and named Ficus virginea from Booby Island in 1770, which was synonymised with F. obliqua by William Philip Hiern in 1901. The species is currently regarded as monotypic. Three varieties of Ficus obliqua were recognised until 2001—F.
County Line Road begins at the end of the 3.6 miles of the Upper San Antonio Road. The last 1.8 miles of which is a hiking, biking, and horse trail within Henry Coe State Park. County Line Road within Henry W. Coe State Park and Orestimba Wilderness is used as a hiking, biking, and horse trail. It is 29.6 miles long within the State Park and begins at altitude of 2,134 feet.
On-board radars can be deceiving. Hail shafts generate weak radar echoes and are significantly more dangerous than cloudbursts. Close to the ground, heavy rain (or snow at altitude) tends to dampen turbulence (it is said that when rain comes, most of the danger is gone). So a counter intuitive recommendation exists: it is better to fly toward the zone of heavy precipitation or toward the darkest area of the thunderstorm line.
Maicao is located in the Guajira Peninsula, the northernmost part of South America and within the Guajira desert. The municipality of Maicao borders to the north with the municipalities of Uribia and Manaure; to the east with the Venezuela; to the south with the municipality of Albania and to the west with the municipality of Riohacha covering a total area of 1,782 km² and at altitude over sea level of 52 m.
The red-billed chough more typically breeds in mountains above in Europe, in North Africa and in the Himalayas. In that mountain range it reaches in the summer, and has been recorded at altitude on Mount Everest. The Alpine chough breeds above in Europe, in Morocco, and in the Himalayas. It has nested at , higher than any other bird species, and it has been observed following mountaineers ascending Mount Everest at an altitude of .
Elmer made the following comments about the species in its type description: > Found among the moss laden cold and windy forested ridge at altitude along > the newly cut trail from lake Danao to the summit of mount Urdaneta or Masay > as the natives call it. The Manobos named this as well as all other pitcher > plants "Lapsay." > > As to our Philippine species it is quite closely related to Nepenthes > merrillii MacF. from Surigao province.
The vegetation in the area is primarily low bushland. Short-tailed chinchillas can be found at El Laco, one of the few occurrences of this threatened species in Chile. El Laco has a classical cold mountain climate at the line between the dry Altiplano with summer precipitation and the hyper-arid Atacama Desert climate. A nearby weather station () at altitude showed an average temperature of in 1991, with strong short-term variability.
Paranal Observatory is an astronomical observatory operated by the European Southern Observatory (ESO). It is located in the Atacama Desert of northern Chile on Cerro Paranal at altitude, south of Antofagasta. By total light- collecting area, it is the largest optical-infrared observatory in the Southern Hemisphere; worldwide, it is second to the Mauna Kea Observatory on Hawaii. The Very Large Telescope (VLT), the largest telescope on Paranal, is composed of four separate telescopes.
Le Vernet and neighbouring communes The village of Le Vernet is located in the Valley at altitude. Its population does not exceed 100 permanent residents, but it is often more than doubled each summer and winter, when the municipality becomes the place of departure for sightseeing excursions, particularly in the Valley, and a place of departure for the nearby ski stations (Grand-Puy, and Chabanon). The municipality has two main villages, Haut-Vernet, perched high and Bas-Vernet below.
Insh Marshes are an area of floodplain of the River Spey between Kingussie and Kincraig in Badenoch and Strathspey, Highland, Scotland. The marshes are said to be one of the most important wetlands in Europe. They lie at altitude of approximately 240 to 220 m above sea level, and form one of the largest areas of floodplain mire and fen vegetation in Scotland. The marshes cover around 11 km2, and hold a number of conservation designations.
His few failures came in Olympic and Commonwealth Games competition. Although favourite for the gold at Tokyo in 1964 he was placed ninth in the 5,000 metres race and the marathon and third in the 10,000 metres. He lost again in the 1966 Commonwealth Games and in 1968 at altitude in Mexico he collapsed at the end of the 10 km race.

The tail is long, 20% longer than the head and body, and is slender marked with 10-14 black bands which alternate with pale bands. There is geographical variation throughout its range with the animals found inland at altitude being the darkest and richest in colour while those from the north of its range are paler while the southerly populations are duller and greyer. The mean head and body length is and the mean tail length is .
13 Aerial photo of Mount Everest from the south, behind Nuptse and Lhotse. There is, however, a complication that increases the volume of air that needs to be inhaled per minute (respiratory minute volume) to provide the same amount of oxygen to the lungs at altitude as at sea level. During inhalation the air is warmed and saturated with water vapor during its passage through the nose passages and pharynx. Saturated water vapor pressure is dependent only on temperature.
This means that the motor test also automatically performs appropriate vibration, stress, and heat tests of the spacecraft structure. The crew cabin, however, is not replicated. For ground-based thrust tests, a rocket nozzle with an expansion ratio of 10:1 is used, differing from the 25:1 nozzle used at altitude during actual flight. The test stand is instrumented to record not only thrust but also side force and temperature and strain experienced by components.
In addition, the radar antenna array is also doubled as an ELINT array, with a maximum range of over 850 km at altitude. Radar signal processing equipment and central computer are installed directly below the antenna array. RAAF Wedgetail aerial refueling during Exercise RIMPAC 2012 Other modifications include ventral fins to counterbalance the radar and countermeasures mounted on the nose, wingtips and tail. In-flight refueling is via a receptacle on top of the forward fuselage.
Sarektjåkkå is not easily accessible by any nearby roads, so the approach normally takes a day or more of backcountry hiking. Accessing the north summit, at altitude, is a moderate but steep hike up. The actual summit (Stortoppen) is located about southwest of the north summit via a ridge and is not as easy to reach, requiring exposed scrambling. An alternative route is to scale the summit from the south by merely steep hiking, but this requires crossing glaciers.
An altitude of 3749m was hit by Marco Levasseur. The ascent of Mont Mégantic by bike is probably the most difficult in Quebec as well as being the highest elevated road in the province. The elevated portions of the many kilometres give a good challenge to those who are facing it. The Tour de Beauce (formerly called the Grand Prix de Beauce) has been partly known in the international cycling world by its arrival at altitude.
Oberst Edgar Petersen, a test pilot at Rechlin, noted the BMW 109-003 performance at altitude precluded any attempt to discover the aircraft's true ceiling, the power plant was never able to deliver full thrust, the nose-wheel was weak, the fuel tank leaked and the performance was generally poor, particularly in the roll; though the fighter was fast. The He 162 proved difficult to fly. JG 1 pilots treated it with scepticism and surprise. Some were enthusiastic.
It had a crew of two in a tandem-seat arrangement with the observer seated higher and offset from the pilot to give a clear view forwards to enable him to assist in visual search. Its operational profile included cruising at altitude (for reduced fuel consumption) before descending, just outside the anticipated enemy radar detection range, to for a Attack Aircraft of the West, Bill Gunston1974, Ian Allan Ltd., , p.33 dash to and from the target.
While the U-2 did not suffer a direct hit, Anderson was struck by fragments from the proximity fused warhead's explosion which penetrated and compromised his pressure suit (at altitude, unconsciousness and death came very quickly). His body was returned to the U.S. following the crisis, still clad in its pressure suit. Major Anderson posthumously became the first recipient of the Air Force Cross. Laughlin's primary operations training complex, Anderson Hall, is named in his honor.
GLONASS is a global navigation satellite system, providing real time position and velocity determination for military and civilian users. The satellites are located in middle circular orbit at altitude with a 64.8-degree inclination and a period of 11 hours and 15 minutes. GLONASS's orbit makes it especially suited for usage in high latitudes (north or south), where getting a GPS signal can be problematic. The constellation operates in three orbital planes, with eight evenly spaced satellites on each.
Other reports indicate the absence of glaciers on Ojos del Salado. Permafrost exists on the mountain and its melting nourishes several lakes; one lake fed by a creek lies at altitude. Ojos del Salado is an active volcano, but the question of whether it should be considered currently (or "historically") active is arguable. According to the Smithsonian Institution's Global Volcanism Program, the most recent known eruption was about 1,300 years ago, with a large margin of uncertainty.
D. russelii is not restricted to any particular habitat, but does tend to avoid dense forests. The snake is mostly found in open, grassy or bushy areas, but may also be found in second growth forests (scrub jungles), on forested plantations and farmland. It is most common in plains, coastal lowlands, and hills of suitable habitat. Generally, it is not found at altitude, but has been reported as far up as 2300–3000 m (7,500-9,800 ft).
The Launch Readiness Review was signed off by all parties on January 15, 2016, and the launch proceeded successfully on January 17, 2016, at 18:42 UTC. The Jason-3 payload was deployed into its target orbit at altitude after an orbital insertion burn about 56 minutes into the flight. It was the 21st Falcon 9 flight overall and the second into a high-inclination orbit from Vandenberg Air Force Base Space Launch Complex 4E in California.
While males congregating at altitude were in abundance, females were infrequently spotted at hill-topping sites, and when present, did not exhibit any territorial behaviour and preferred locations near the substrate. Female absence may be due to females only visiting the congregation sites when ready to mate. Although the behaviour of males and females at elevation are considered to be for mating purposes, direct evidence of this is lacking and little is known of their courtship and mating rituals.
The Garcia's Pass is a mountain pass across the Langeberg in the Western Cape province of South Africa, with its highest point at altitude. The regional road numbered R323 uses this pass on its leg between Riversdale in the south and Ladismith in the Little Karoo to the north. From Riversdale, the road winds to the Garcia Pass across the Langeberg to Muiskraal in the northern foothills. The maximum slope is 1:14 on the southern descend.
Still called "Villa Montalvo" by local area residents, the Montalvo Arts Center hosts a arboretum and botanical garden, located behind the center. It is free and open to the public during daylight hours and run as part of a non-profit organization for art, artists, and the local community. The arboretum is adjacent to the villa and is an Audubon Society bird sanctuary. There are dirt paths leading out of a redwood canyon to Lookout Point at altitude .
A few examples were fitted with the lower powered Clerget 9Z. As a result of the Clerget's slightly greater diameter, the cowling was ballooned out slightly to provide clearance. The majority of Nieuport 17bis were operated by 6 (Naval) Squadron, who tested them against a Sopwith Triplane and a Sopwith Camel. It was found to have similar manoeuvrability to the Triplane and have a higher dive speed, but was slightly slower at altitude and had heavier controls.
An F-111A drops 24 Mark 82 low-drag bombs in- flight over a bombing range. The F-111A was the initial production version of the F-111. Early A-models used the TF30-P-1 engine. Most A-models used the TF30-P-3 engine with 12,000 lbf (53 kN) dry and 18,500 lbf (82 kN) afterburning thrust and "Triple Plow I" variable intakes, providing a maximum speed of Mach 2.3 (1,450 mph, 2,300 km/h) at altitude.
Early in its development, the Camel was simply referred to as the "Big Pup". A metal fairing over the gun breeches, intended to protect the guns from freezing at altitude, created a "hump" that led pilots to call the aircraft "Camel", although this name was never used officially.Bruce 1965, pp. 4-5. On 22 December 1916, the prototype Camel was first flown by Harry Hawker at Brooklands, Weybridge, Surrey; it was powered by a 110 hp Clerget 9Z.
Despite being called an interceptor, the proposed aircraft's role was simply an extension of the traditional pursuit (fighter) role, using a heavier and more powerful aircraft at higher altitude. Specifications called for at least 1,000 lb of heavy armament including a cannon, a liquid-cooled Allison engine with a General Electric turbo-supercharger, tricycle landing gear, a level airspeed of at least at altitude, and a climb to within 6 minutes.Lockheed P-38 Lightning. Retrieved: 21 January 2007.
Aurelia Catalina Pentón Conde (born February 13, 1941) is a retired track and field athlete from Cuba, who competed in the 400 and 800 metres during her career. Pentón was born in Sancti Spíritus, and twice represented her native country at the Summer Olympics: 1968 and 1972. Her time of 50.56, set at altitude in Medellín, Colombia while winning the 1978 Central American and Caribbean Games is the officially ratified masters athletics world record for the W35 400 metres.
Four different computer models produced similar results; they concluded that the likeliest candidate for the Tunguska impactor was a stony body between in diameter, entering the atmosphere at roughly , exploding at altitude, and releasing explosive energy equivalent to between 10 and 30 megatons. This is similar to the blast energy equivalent of the 1980 volcanic eruption of Mount St. Helens. The researchers also concluded impactors of this size hit the Earth only at an average interval scale of millennia.
The development program ran into many problems with this engine, including the original electronic control system, compressor/turbine mismatches, combustion instability and control issues at altitude leading to compressor stalling The produced -8, -8A and -8B engines were all derated from the original design specification on both thrust and specific fuel consumption.Aero Engines 1954 (1954). Flight. 9 Apr 1954. pg 461 The engine featured a 12-stage compressor that was driven by two turbine stages on a single shaft.
Chaghar matti is located 17 km away to the North West from Capital Peshawar and 5 km from warsak road. Chaghar Matti is at altitude of 345m (1,135 ft) above sea level. The Village is located in the Plain Area surrounded by the green and fertile fields. To the East of Chaghar matti, Peshawar city is situated, to the West Bara and Warsak, to the North Mechani and Shabqadar and to the South, University road is situated.
Believing that they had both climbed above the 23,000-foot (7,000 m) mark, Fanny and William now considered themselves the leading experts on climbing at altitude. Workman vigorously defended her Pinnacle Peak altitude record against all other claimants, especially Annie Smith Peck. In 1908, Peck claimed a new record with her climb of Peru's Huascarán, which she believed to be . However, she was misinformed as to the peak's height and exaggerated distances she could not measure.
Engstingen is a municipality in the Tübingen administrative region (Regierungsbezirk) in Baden-Württemberg, Germany. It lies in the Swabian Jura (plateau), about south of Reutlingen. It was formed on January 1, 1975 from the former independent municipalities of Großengstingen, Kleinengstingen and Kohlstetten. Engstingen is located on the northern edge of the Swabian Jura, at altitude on the Alb plateau near the Alb edge in the valley of Ur-Lauter, about 15 km south of the town Reutlingen.
Simone Collio (born December 27, 1979 in Cernusco sul Naviglio) is an Italian sprinter who specializes in the 60 and 100 metres.Athlete biography: Simone Collio, beijing2008.cn, ret: Aug 26, 2008 His personal best times are 6.55 seconds in the 60 metres (indoor) and 10.06 seconds in the 100 metres, the third all-time best performance in the Italian ranking of 100 meters, after the 10.01 at altitude of Pietro Mennea and 9.99 of Filippo Tortu.
All were hindered by an unexpected strong headwind at altitude. L 45 was trying to reach Sheffield, but instead it dropped bombs on Northampton and London: most fell in the north-west suburbs but three 300 kg (660 lb) bombs fell in Piccadilly, Camberwell and Hither Green, causing most of the casualties that night. L 45 then reduced altitude to try to escape the winds but was forced back into the higher air currents by a B.E.2e.
The six-cylinder Renault 6Q and the four-cylinder Renault 4P, both from the early 1930s, shared the same bore, stroke and pistons. The 6Q was built in both unsupercharged and supercharged forms. The centrifugal supercharger was added at the back of the engine, driven off the crankshaft via step-up gearing. It added to the weight and to the length but boosted the performance at altitude to a continuous power of at 2,500 rpm and .
Beset by bad weather, they stayed at Camp III for two days until Wyn Harris persuaded Ruttledge, against his better judgement, to allow him and Shipton to try again. They only just survived a massive avalanche on the steep slope up to the Col. Shipton later wrote "It was a ridiculous thing to do, but we were rather desperate." So, the attempt on the summit failed without their oxygen equipment having been able to be tested at altitude.
Fortress is an isometric scrolling shooter in which the player manoeuvres a starfighter along an alley-like terrain. The player craft burns fuel rapidly (even more when flying at altitude) and fuel tanks need to be destroyed to replenish the on-board fuel tank. If the craft runs out of fuel, it crashes. The player must avoid enemy gun turrets, rocket pits and fighters, and deal with additional problems of navigating over and through walls with force fields.
The Cinderella waxbill is found in subtropical and tropical (lowland) dry shrubland, savannah and forest habitats at altitude of 200 to 500 m. It is observed that the recent development of a hydroelectric plant on the Cunene River at Epupa Falls has caused changes to insect biodiversity which were relied on by the Cinderella waxbill during feeding of its young. Thus threatening its food source to be depleted. The waxbill also eats grass seeds, nectar and insects.
Picea engelmannii, with common names Engelmann spruce, white spruce, mountain spruce, or silver spruce, is a species of spruce native to western North America, from central British Columbia and southwest Alberta, southwest to northern California and southeast to Arizona and New Mexico; there are also two isolated populations in northern Mexico. It is mostly a high altitude mountain tree, growing ataltitude, rarely lower in the northwest of the range; in many areas it reaches the alpine tree line.
A 1994/1995 study published in 1997 by Marchant and Taylor did a pollen analysis on and radiocarbon-dated two core samples from montane Mubindi Swamp in Uganda. The swamp is a catchment at altitude between mountain ridges. It is a "moist lower montane forest" in Bwindi Forest National Park. The investigators found montane Prunus, represented by currently growing P. africana, has been in the catchment continuously since their Pollen Zone MB6.1, dated about 43,000–33,000 years ago.
Following the work of HAPP, the CRC started work on their own version with the specific intent of making a communications platform. SHARP would use an 80 m diameter array of small parabolic dishes beaming 500 kW of power to the aircraft at 5.8 GHz frequency. At altitude, the beam was focussed down to an area just larger than the aircraft. The aircraft normally flew in a circle about 2 km across, so the beam only needed to steer a few degrees.
Museum of Toulouse The natural range extends from southern Sweden to northern Sicily, west to France, southern England, northern Portugal, central Spain, and east to northwest Turkey, where it intergrades with the oriental beech (Fagus orientalis), which replaces it further east. In the Balkans, it shows some hybridisation with oriental beech; these hybrid trees are named Fagus × taurica Popl. [Fagus moesiaca (Domin, Maly) Czecz.]. In the southern part of its range around the Mediterranean, it grows only in mountain forests, at altitude.
Especially against bombers the Fw 190 was by far superior > because of its heavy armament, its lower vulnerability, and its better > protection for the pilot. All these features were favourable for bomber and > schlachtflieger operations. The evaluation was that the Bf 109 was superior in all around performance "at altitude" [20,000 ft]. The drop in performance was a problem on the Western front during the Defense of the Reich campaign, as most of the fighting took place above 20,000 feet.
Flemingia macrophylla a is woody leguminous shrub belonging to the genus Flemingia. It is a multipurpose plant widely used in agriculture, crop improvement, fodder, dyes and for various therapeutic purposes. Perhaps, it is the most versatile species of Flemingia in terms of adaptation, medicinal and agricultural applications. It is a native plant of subhumid to humid (sub-) tropics where average annual rainfall is typically 1100–3500 mm with up to 6 dry months, at altitude up to 2000 m above msl.

's Peter Sagan (pictured in stage nineteen) held the green jersey from the end of stage eleven to the end of the Tour, claiming his fourth consecutive points classification title. Stage ten was the race's first arrival at altitude with the finish at La Pierre Saint-Martin in the Pyrenees. The day's breakaway was caught and passed on the final climb by a select group. Froome attacked with remaining to take the win, with teammate Richie Porte and Quintana a minute in arrears.
The satellites in the OneWeb constellation are approximately in mass, a bit smaller than the 2015 design estimate of . The 648 operational satellites are to operate in 18 polar orbit planes at altitude. The satellites will operate in the Ku-band, communicating in the microwave range of frequencies in the 12–18 GHz portion of the electromagnetic spectrum. The satellites use a technique called "progressive pitch" in which the satellites are slightly turned to avoid interference with Ku-band satellites in geostationary orbit.
A number of realistic gliders and balloons were built for the film. A total of 11 gliders that reproduced Montgomery's original three gliders were built. In an attempt to duplicate the balloon launch of a glider at altitude, the stunt nearly was disastrous when the balloon suddenly flew uncontrollably up to 16,000 ft before the test pilot was able to control the gas release valve and bring the balloon back down to the intended 4,000 ft. The sequence was then shot safely.
It was then re-designated as the MS.222. The MS.222 climbed faster than the MS.221 but was still slow at altitude, so a further aerodynamic clean-up in 1930 replaced the cross-axle undercarriage inherited from the MS.121 with a split-axle design, resulting in the MS.223 which first flew in April 1930. By this time the failure of the "Jockey" programme was apparent and Morane-Saulnier turned their attention back to heavier, more traditional fighters.
The energy needed per unit distance increases by the square of the velocity and the time decreases linearly. For example, 2.5 times as much power is needed to travel at than . Aircraft take advantage of lower air pressure and lower temperatures by cruising at altitude to reduce energy consumption but unlike trains need to carry fuel on board. This has led to the suggestion of conveying maglev vehicles through partially evacuated tubes or tunnels with the possibility of supplying energy from renewable sources.
On 1 November, Dee performed an experiment in which he used an AIS radar mounted on a Blenheim to scan the ground. Using this display he was able to pick up the outline of a town away while flying at altitude. The commanders were impressed and, on 1 January 1942, the Telecommunications Research Establishment (TRE) set up a team under Bernard Lovell to develop an S-band airborne targeting radar based on AIS. An initial order for 1,500 sets was placed.
The Type 85, originally for aircraft tracking, would provide early warning in Violet Friend. The entire Violet Friend system was highly reliant on the earliest possible warning of an attack. A radar in the UK mounted at like the Type 85 had a radar horizon against a missile at altitude at just over . Several Type 85s were to continually scan the horizon to look for launches, feeding this information both to their associated battery as well as to each other via datalink.
UND played one more home game against the Winnipeg Maroons before heading out on an arduous road trip. Their first stop was in Houghton the following weekend where Michigan Tech was waiting to exact revenge. The Huskies stifled UND in both games, holding the Fighting Sioux to a single goal over the weekend and comfortably took both matches. Three days later North Dakota found themselves at altitude in Colorado where they played four games in five days against Denver and Colorado College.
Joseph Barcroft, in 1920, spent six days in a sealed glass chamber to investigate respiration at altitude. The partial pressure of oxygen was initially 163 mmHg falling to 84 mmHg (equivalent to an altitude of 18,000 ft) as the experiment progressed. Barcroft was attempting to disprove a theory of John Scott Haldane that the lungs actively secrete oxygen into the blood (rather than just through the process of passive diffusion) under conditions of low oxygen partial pressure. Barcroft suffered from severe hypoxia.
The imperial snipe occurs around the tree-line at altitude in mosaic habitats consisting of a mixture of bogs, mossy areas, moist elfin forest, tree-ferns and tall grass. Little is known about its habits and it is mostly observed when displaying. The dawn and dusk aerial display involves flying high in circles performing the extremely loud song. This is followed by a dive during which the bird makes a drumming sound caused by the vibrations of its modified outer tail feathers.
Some experienced pilots are able to take a flight in one direction then rise to a different altitude to catch wind in a returning direction. With experience, luck, and the right conditions, some pilots are able to control a precision landing at the destination. On rare occasions, they may be able to return to the launch site at the end of the flight. This is sometimes called a box effect, when winds at altitude flow in the opposite direction of surface winds.
View of the Mondarrain from the village of Espelette Mount Mondarrain (Arranomendi in Basque) is in the French Basque Country, south of Espelette and south-west of Itxassou in the province of Labourd , peaking at altitude. To prevent Marquess of Wellington's army invading France in 1813, Marshal Soult built a line of fortifications and entrenchments along the river Nivelle from the sea inland to fortified rocks on Mount Mondarrain. The lines were breached during the Battle of Nivelle 10 November 1813.
In September 1940, Britain ordered 386 P-39Ds (Model 14), with a 20 mm (.79 in) Hispano-Suiza HS.404 and six .303 in (7.7 mm), instead of a 37 mm (1.46 in) cannon and six 0.30 in (7.62 mm) guns. The RAF eventually ordered a total of 675 P-39s. However, after the first Airacobras arrived at 601 Squadron RAF in September 1941, they were promptly recognized as having an inadequate rate of climb and performance at altitude for Western European conditions.
An altitude tent is a sealed tent used to simulate a higher altitude with reduced oxygen. Living or training at altitude causes the body to adapt to the lower oxygen content by producing more oxygen-carrying red blood cells and hemoglobin, thus causing the body to adapt to the higher altitude and enhancing performance when returning to a lower altitude. Mountain climbers can use them to avoid altitude sickness, and athletes can use them to enhance performance at lower altitudes.
Thanks to the efforts of the 151st Maintenance unit, the 51 Hurricanes were assembled and ready for testing within 48 hours and of these, 21 were ready for operational service within three days. The Hurricanes were fitted with bulky 'Vokes' dust filters under the nose and were armed with 12, rather than eight, machine guns. The additional weight and drag made them slow to climb and unwieldy to manoeuvre at altitude, although they were more effective bomber killers.Shores 1992, p. 297.
Pinus jeffreyi occurs from southwest Oregon south through much of California (mainly on the eastern side of the Sierra Nevada), to northern Baja California in Mexico. It is a high-altitude species; in the north of its range, it grows widely at altitude, and at in the south of its range. Pinus jeffreyi is more stress tolerant than Pinus ponderosa. At higher elevations, on poorer soils, in colder climates, and in dryer climates, Pinus jeffreyi replaces Pinus ponderosa as the dominant tree.
Colledge's guideless ascent of a number of difficult routes in the Alps resulted in an invite to join Eric Shipton's Cho Oyu expedition in 1952. The expedition included many climbers who would later form the successful Everest team in 1953. During the expedition, Colledge made the first ascent of a number of lesser peaks"Repimo Shar". GREATER HIMALAYA - Climb Magazine, and was one of the test subjects who worked closely with the physiologist Griffith Pugh to test oxygen flow rates at altitude.
It also frequents cool rainforest of beech, king billy pine (Athrotaxis selaginoides). In lowlands it is more restricted to denser forests and moist gullies, while it also occurs in alpine scrubland and heathland at altitude. In dryer more open forest, it is replaced by the clinking currawong, although the two may co-occur in places such as the Central Highlands and Eastern Tiers. Both the Flinders and King island subspecies are found across their respective islands, but prefer more forested habitats there.
904 g) and an atmosphere that provides a level of protection from solar and interstellar radiation. Whereas all ground missions measured their operational time in minutes or hours, the Soviet Vega missions found success in launching small balloons, that operated until their batteries were exhausted (days). At altitude, the atmosphere of Venus is and (the equivalent pressure at an elevation of about on Earth). However, due to the large amount of , the density for a given pressure is greater than in Earth's atmosphere.
Jagdschloss units were found to have several "dead spots" due to the antenna being located on an tower. For instance, an aircraft flying at altitude at any range between would be invisible because the direct reflection from the aircraft would interfere with the one reflecting off the ground. This problem was initially solved with the addition of a large wire mesh under the tower, known as Reflektor-Netz. Erstling codegenerator A more convincing solution to this problem was deployed as Jagdschloss Michael.
Some lake water highstands of Salar de Atacama are associated with Lake Tauca's main highstand phase During the Tauca phase, a large lake formed at Lake Titicaca; the pampas around Titicaca were left by that lake and the paleolake Minchin. Lake Titicaca rose by about , reaching a height of , and its water became less saline. Another shoreline, at altitude, has been linked to a highstand of Lake Titicaca during the Tauca epoch. The highstand, in 13,180 ± 130 BP, is contemporaneous with the Tauca III phase.
The Ticaña phase was accompanied by a drop in water level. The Tauca and Coipasa phases are sometimes considered separate. Lakes Tauca and Minchin have been considered the same lake system and called Lake Pocoyu, after the present-day lakes in the area. "Minchin" is also used by some authors as a name for the system. The Tunupa volcano was glaciated during the Tauca episode The Chita tuff was deposited in Lake Tauca at altitude approximately 15,650 years BP, when the lake may have been regressing.
At an elevation of above sea level, Qamdo Airport was formerly the highest airport in the world. It was surpassed by Daocheng Yading Airport, with an elevation of , on 16 September 2013. It has a very long runway, at , a necessary feature due to the reduction in engine and lift performance that aircraft are subject to at altitude, requiring higher than normal lift-off speeds and therefore longer take-off (and landing) runs. The airport is 2.5 hours by road from the county seat of Qamdo.
The storm field drew across Western Europe on 30 and 31 March 2015, reaching the Netherlands and large areas of Germany on 31 March 2015. Hurricane-force winds were reported in Germany, according to the German Weather service (DWD) with a peak gust at altitude on the mountains of Zugspitze (), the Brocken (), Feldberg in the Black Forest () and on Weinbiet in Neustadt (). At lower elevations on the North Sea coast peak gusts of were reported. The storm was absorbed by windstorm Oskar on 6 April.
The air entering the lungs also has a total pressure of 33.7 kPa, of which 6.3 kPa is, unavoidably, water vapor (as it is at sea level). This reduces the partial pressure of oxygen entering the alveoli to 5.8 kPa (or 21% of [33.7 kPa – 6.3 kPa] = 5.8 kPa). The reduction in the partial pressure of oxygen in the inhaled air is therefore substantially greater than the reduction of the total atmospheric pressure at altitude would suggest (on Mt Everest: 5.8 kPa vs. 7.1 kPa).
Calvert 1991, p. 23. They entered service with No. 74 Squadron RAF (Tiger Squadron), based at RAF Wattisham in the air-defence role. Crews liked the aircraft, and generally rated them better than the Spey-equipped FGR.2s. They had a slower rate of climb due to the less-powerful engines, but they were also 1,670 lb (760 kg) lighter and able, at altitude, to reach higher speeds (Mach 2.3 at 45,000 ft/13,700 m, compared to Mach 2.1 at 36,000 ft/11,000 m).
Porters are still paid to shift burdens in many third-world countries where motorized transport is impractical or unavailable, often alongside pack animals. The Sherpa people of Nepal are so renowned as mountaineering porters that their ethnonym is synonymous with that profession. Their skill, knowledge of the mountains and local culture, and ability to perform at altitude make them indispensable for the highest Himalayan expeditions. Porters at Indian railway stations are called coolies, a term for unskilled Asian labourer derived from the Chinese word for porter.
Lisa Grossman, "NASA Considers Shooting Space Junk with Lasers" , wired, 15 March 2011. Crewed space missions are mostly at altitude and below, where air drag helps clear zones of fragments. The upper atmosphere is not a fixed density at any particular orbital altitude; it varies as a result of atmospheric tides and expands or contracts over longer time periods as a result of space weather. These longer-term effects can increase drag at lower altitudes; the 1990s expansion was a factor in reduced debris density.
Tournant is the world record holder (at altitude) for the Kilo (1000m time trial). He first set the record in Mexico in 2000, with a time of 1:00.148. In October the following year, at the age of 23, Tournant became the first man to go under the one-minute mark, breaking his own world record with a new time of 58.875 seconds set at La Paz, Bolivia. Chris Hoy came to within 0.005 seconds of Tournant's record on his second attempt, but failed to beat it.
Precise dating methods performed on the southeastern flank have found ages of 3.65±0.15 mya and 3.81±0.30 for lavas and scoria. The snowline altitude in the area is Four moraine stages are found on the mountain, with the lowest moraines on the southern flank at altitude. Nowadays, block glaciers have been identified in the area, one of which is found at . The mountain is also one of the headwaters of the Loa River, and water was transferred from Palpana to Antofagasta by pipeline.
Wykes, J. H. "AIAA-1972-772, B-1 Structural Mode Control System." American Institute of Aeronautics and Astronautics (AIAA), 9 August 1972. Retrieved: 3 August 2011. alt= A rear view of a B-1B at Royal International Air Tattoo air show in 2004 Unlike the B-1A, the B-1B cannot reach Mach 2+ speeds; its maximum speed is Mach 1.25 (about 950 mph or 1,530 km/h at altitude), but its low-level speed increased to Mach 0.92 (700 mph, 1,130 km/h).
At altitude, for instance in the Alps, where there are not large Populus forests, they accommodate with a grove, in the southeast of France they can be seen flying in large open spaces, for instance in the department of Alpes-Maritimes, as noted by Jacques Rigout.Rigout J. (1969). Observations et captures intéressantes (Nymphalidae, Papilionidae), Alexanor 6(4):174-176 The males are easier to find. The females are rarer, because they tend to stay in the tops of the trees and seldom venture to the ground.
The seventh All-Africa Games were held in September 1999 in Johannesburg, South Africa. As the track is at an altitude of 1748 metres all performances are considered to be set at altitude, this is believed to assist events up to 400 metres and in the long jump and triple jump. However, for events beyond 800 metres the thinner air is believed to have a detrimental effect on performances. Maria de Lurdes Mutola of Mozambique won her third 800 metres title in a row.
At Brevard Zoo The Moluccan king parrot inhabits rainforests, but sometimes enters nearby plantations and gardens. Exceptionally, it occurs at altitude up to 2100 m, but more commonly below 1200 m (New Guinea) or 1600 m (Maluku). It is generally uncommon due to habitat loss and capture for the parrot trade, but remains locally common at least on the Sula Islands, Halmahera, and Buru. Overall, the species is not believed to be in immediate danger, and consequently is listed as least concern by BirdLife International and IUCN.
Three Lancasters of 44 Squadron flying in formation at altitude For Arthur Harris, Bomber Command's commander in chief, the Schneider plant was the highest priority target in France. To minimize loss of life to French civilians any attack on the plant would have to be made during the day. In his arsenal he had a new bomber in service that was now coming to the force in significant numbers. A four engine aircraft, the Avro Lancaster had excellent range, a tremendous lift capacity and was fast.
Early aircraft were light and basic, and needed a reliable lightweight engine for power. JAP motorcycle engines were often used in this application. A JAP engine was originally fitted in A V Roe's 1909 triplane, regarded as the first all-British aircraft, and for a while Prestwich and Roe had a partnership. JA Prestwich at first would deliver the same engine to the aircraft manufacturer, allowing them to make local modifications – mainly larger venturi tubes for the carburettor, to allow for greater air intake at altitude.
This called for a significantly more advanced design with higher speeds, longer range and larger payloads. This was also the same day that Wever was killed in an air crash, and the design lost its only politically powerful champion.Griehl and Dressel 1998, p. 8. The specification required the plane to carry a bomb-load of at least 1,000 kg (2,200 lb) over a range of 5,000 km (3,100 mi), with a maximum speed of not less than 500 km/h (311 mph) at altitude.
On October 1, 1966, a Douglas DC-9 registered in the United States as N9101 operated as Flight 941 from Seattle, Washington to San Francisco, California with intermediate stops in Portland and Eugene. After approximately one hour on the ground, the aircraft and crew became Flight 956, which reversed the route and stops of the previous flight. Flight 956 arrived in Eugene at 19:34 and departed for Portland at 19:52. The flight received an Instrument Flight Rules (IFR) clearance via Victor Airway 23 at altitude.
Dropsonde delivery system on a NOAA P-3 Hurricane Hunter. A dropsonde is an expendable weather reconnaissance device created by the National Center for Atmospheric Research (NCAR), designed to be dropped from an aircraft at altitude over water to measure (and therefore track) storm conditions as the device falls to the surface. The sonde contains a GPS receiver, along with pressure, temperature, and humidity (PTH) sensors to capture atmospheric profiles and thermodynamic data. It typically relays this data to a computer in the aircraft by radio transmission.
Some launch systems use flight termination for range safety. In these systems the RSO can remotely command the vehicle to self- destruct to prevent the vehicle from traveling outside prescribed safety zone. This allows as-yet-unconsumed propellants to combust at altitude, rather than upon the vehicle reaching the ground. Space vehicles for sub-orbital and orbital flights from the Eastern and Western Test Ranges were destroyed if they endangered populated areas by crossing pre-determined destruct lines encompassing the safe flight launch corridor.
Category:Municipalities in Minas Gerais Ouro Fino is a Brazilian municipality in the state of Minas Gerais. Its population estimated in July 2016 was of 33 557 inhabitants. It is situated in a mountainous region, being cut by valleys, with altitudes varying between 997 and 1591 meters. Its climate is tropical at altitude, with rainy and mild summer and dry period in the winter, with nights and cold dawns. Average annual temperature of 18 ° C, with maximums of 36 ° C in summer and 5 ° C in winter.
Two streams which are sources of the Pleisbach, the Logebach and the Quirrenbach, rise in the area and run through it. The Kochenbach is a tributary of the Quirrenbach. Amongst the hills within the district of Aegidienberg are the Himberg (), the Hupperichsberg (According to the Deutsche Grundkarte; topographic map, ), the Markhövel (also called the Romert; ) and the Dachsberg (According to the Deutsche Grundkarte; topographic map, )--the last being the highest point in the district. The main village of Aegidienberg, on the eponymous hill, is at altitude.
In New South Wales, the species is widespread in rainforest southwards to the Blackwall Range near Wardell and the Cherry Tree State Forest near Mallangangee (Braby 2000, Sands & New 2002, Sands & Scott 1997). Note that although the species may be abundant at altitude (e.g. the Queensland-New South Wales border ranges national parks), these populations typically die out due to cold winter temperatures and require migration of adults from the lowlands for persistence. Population sizes in these habitats therefore vary from year to year.
These are the official results of the Women's 100 metres event at the 1983 IAAF World Championships in Helsinki, Finland. There were a total number of 49 participating athletes, with seven qualifying heats and the final held on Monday 1983-08-08. Evelyn Ashford set the World record just over a month before this meet (at altitude). In the semi-finals, she dusted one of the East German favorites Marita Koch eased up by almost a tenth of a second out in lane 8.
The rear radome is shortened and reshaped to prevent its striking the deck during high-Alpha (angle of attack) landings.Eden 2004, p. 463. Compared with the rival MiG-29K, the Su-33's maximum takeoff weight (MTOW) is 50% higher; fuel capacity is more than double, allowing it to fly 80% further at altitude (or 33% at sea level). The MiG-29K can spend as much time as the Su-33 on station by using external fuel tanks, but this limits its ordnance capacity.
Beamon's jump is still the Olympic record and years later remains the second longest wind legal jump in history. (Beamon's jump was at the very limit, 2.0 metres per second, of wind assistance and was at altitude, though the next-best jump under the same conditions in 1968 was Ralph Boston's 8.16 metres). Sports journalist Dick Schaap wrote a book about the leap, The Perfect Jump, and the feat was named by Sports Illustrated magazine as one of the five greatest sports moments of the 20th century.
The maximum speed is classified, though sources state a maximum speed greater than Mach 2 at altitude and a supercruise speed greater than Mach 1.6.Aronstein 1998, p. 136. The aircraft's weapons bay was configured for weapons launch, and used for testing weapons bay acoustics, but no missiles were fired; Lockheed fired AIM-9 Sidewinder and AIM-120 AMRAAM missiles successfully from its YF-22 demonstration aircraft. PAV-1 performed a fast-paced combat demonstration with six flights over a 10-hour period on 30 November 1990.
Six electric driven propeller engines are installed on the wings that generate a combined thrust of 250 lbf at sea level. Although the power output remains constant as altitude increases the propellers lose their effectiveness but are still able to provide cruising speed of 152 km/h at altitude for the Explorer and 100 km/h for the Pioneer. The electrical motors are powered by internal batteries during night and solar panels during daytime. The solar panels generate 2800W for the Explorer and 1800W for the Pioneer..
A Japanese study found nests in trees from many families; these included grey alder, Japanese white birch, Japanese hop-hornbeam, Japanese tree lilac, willows, Japanese larch and Sargent's cherry. The Mongolian oak and prickly castor-oil tree were rarely if ever used. The typical clutch is four to six glossy white eggs that measure and weigh about , of which 7% is shell. They are laid from mid-April to June, the later dates being for birds breeding in the north of the range or at altitude.
Axis fighters and fighter-bombers were able to make undetected low-level approaches from Catania under the fleet's radar horizon by flying down the Acate River canyon at the eastern edge of the Gela beachhead. Allied fighters patrolling at altitude to engage medium bombers were perceived as dive bombers and subjected to friendly fire losses when they attempted to engage low altitude air raids.LaMonte & Lewis (1993) pp.5-6,19,62,67,71,89&92 Ships were using proximity fuzed anti- aircraft ammunition for the first time in the European theater.
In March 2019, following a disappointing start of the season, Aru was diagnosed with a constriction of the iliac artery and underwent an angioplasty surgery, which forced him out from racing for several months. As a result, his immediate plans to ride the Volta a Catalunya, as well as the Giro d'Italia were abandoned. Aru was back on his bike at altitude training in Sestriere in May. He made his comeback to racing in June, at the Gran Premio di Lugano where he finished 22nd.
Two of them meet at a tambo or inn at an altitude of , while the third passes through a cementerio (cemetery) where 16 bodies were found in 1972 before reaching the tambo. From the tambo another path leads up the mountain, past two further archeological sites to of altitude. At this altitude the path is marked by cairns, probably to indicate where the path is when the volcano is covered by snow. The path ends at altitude at the Portezuelo del Inca ruins, where a staircase begins.
Britannia Bridge after rebuilding Other innovative projects Husband & Co. undertook under Husband's leadership included designing a facility for testing jet engines at altitude in 1946. In the 1950s, Husband assisted the radiologist Frank Ellis in designing one of the earliest telecobalt radiotherapy units, for radiation treatment of cancer, which was installed at the Churchill Hospital in Oxford. Like the radio telescopes, the engineering problem involved moving a heavy weight, in this case the lead- shielded source, in three dimensions. He designed many road and rail bridges.
The launch occurred on 22 July 2019 at 09:13 UTC (14:43 IST) on the first operational flight of a GSLV MK III M1. On 6 September 2019, the lander during its landing phase, deviated from its intended trajectory starting at altitude, and had lost communication when touchdown confirmation was expected. Initial reports suggesting a crash were confirmed by ISRO chairman K. Sivan, stating that "it must have been a hard landing". The Failure Analysis Committee concluded that the crash was caused by a software glitch.
The 2018 USA Track & Field Indoor Championships were held at the Albuquerque Convention Center in Albuquerque, New Mexico. Organized by USA Track and Field (USATF), the three-day competition took place from February 16 to February 18 and served as the national championships in indoor track and field for the United States. All marks in the competition are considered at altitude. The meet serves for the selection of American representatives at the 2018 IAAF World Indoor Championships held in Birmingham March 1 to March 4.
It was the fastest performance from a Ghanaian since 1995 and also qualified him for the 2019 World Athletics Championships. Later in June of that season at the NCAA Division I Championships, he improved his personal best times in the 100 metres and 200 metres to 10.01 seconds and 20.08 seconds respectively. He broke three-time Olympian Emmanuel Tuffour's 24-year old Ghanaian record in the 200 metres (20.15 seconds, set at altitude), and qualified for the 2020 Summer Olympics in the 100 metres.
No. 52-2711 of the 509th Bomb Wing,JoeBaugher.com: 1952 USAF Serial Numbers , Retrieved on 2011-12-1 out of Walker AFB, New Mexico, crashed 35 miles north of Flagstaff, Arizona, while on a nine-hour low-level survey flight to determine minimum altitude restrictions for B-47 training routes. The aircraft was seen over Gray Mountain, Arizona, at altitude of 60 feet shortly after 0830 hrs., and then heard striking a cloud-shrouded cliff face, killing 16 crew and strewing wreckage for 200 yards along mountainside.
At the 1992 Barcelona Olympics, she won a gold medal in the sprint relay, running the second leg. Her teammates were Evelyn Ashford, Carlette Guidry and Gwen Torrence. Jones' best legal times are 11.11 secs (July 1991) in the 100 metres, set in Rhede, and 22.47 secs (May 1992) in the 200 metres, set in San José. In the 100 m, she also ran a wind-aided 10.99 (+5.2) in Eugene (June 1991) and an 11.09 at altitude in El Paso (April 1994), with no wind gauge.
The Wib 3, or Wib 3 C.1 (the C for Chasseur or fighter, 1 indicating single seat) was Wibault's response to a call from the Service Technique de l'Aéronautique (S.T.Aé, Technical Department of Aeronautics) for a high altitude fighter. This was required to have a top speed of at and a service ceiling of ; to achieve this performance at altitude, the specification called for a turbocharged engine. It was an all-metal aircraft in the contemporary sense, with a structure of duralumin but largely fabric covering.
BOAC Flight 781 was a de Havilland Comet passenger jet, operated by British Overseas Airways Corporation (BOAC), that crashed on 10 January 1954 after suffering an explosive decompression at altitude. The Comet crashed into the sea near Elba Island, off the Italian coast, killing all 35 people on board. The aircraft, registered had taken off shortly before from Ciampino Airport in Rome, en route to Heathrow Airport in London, on the final leg of its flight from Singapore. G-ALYP was the third Comet built.
The pendulum is expected to run more slowly at altitude, but the mass of the mountain will act to reduce this difference. This experiment has the advantage of being considerably easier to conduct than the 1774 one, but to achieve the desired accuracy, it is necessary to measure the period of the pendulum to within one part in one million. This experiment yielded a value of the mass of the Earth of , corresponding to a mean density of .Taking the volume of the Earth to be .
Positioning artillery observers on balloons, generally a few miles behind the front lines and at altitude, allowed them to see targets at greater range than they could on the ground. This allowed the artillery to take advantage of its increased range. German Balloon Corps, 1910 Because of their importance as observation platforms, balloons were defended by anti-aircraft guns, groups of machine guns for low altitude defence and patrolling fighter aircraft. Attacking a balloon was a risky venture but some pilots relished the challenge.
The airliner's four Curtiss Wright R-1820 radial engines used crankshaft-driven two-speed superchargers both for added power and for greater performance at altitude. To provide pressurized air for the proposed cabin, the two inboard engines also drove (via a shaft) an additional supercharger mounted on each engine's firewall. Dr. W. Randy Lovelace of the Mayo Clinic, was consulted; he advised that cabin pressurization begin at 8,000 feet MSL. Then pressurized air would be added as required to maintain an 8,000-foot cabin pressure.
Dajti Castle () is a archaeological site in Albania, comprising the ruins of a Roman fortification and several dwellings. It belongs to late antiquity, probably having been built over Illyrian foundations. It lies at altitude on top of a hill, west-side of Mount Dajti, close to Tirana.Besnik Aliaj, Keida Lulo, Genc Myftiu - TIRANA, the Challenge of Urban Development (Archaeological evidence in Tirana district, page 133) Publisher: SEDA, Tirana 2003 It was discovered in 1963 and eventually was inscribed in the list of the Cultural Monuments of Albania.
Pre-acclimatization is when the body develops tolerance to low oxygen concentrations before ascending to an altitude. It significantly reduces risk because less time has to be spent at altitude to acclimatize in the traditional way. Additionally, because less time has to be spent on the mountain, less food and supplies have to be taken up. Several commercial systems exist that use altitude tents, so called because they mimic altitude by reducing the percentage of oxygen in the air while keeping air pressure constant to the surroundings.
U.S. regulations on general aviation aircraft (non-airline, non-government flights) require that the minimum required flight crew, but not the passengers, be on supplemental oxygen if the plane spends more than half an hour at a cabin altitude above . The minimum required flight crew must be on supplemental oxygen if the plane spends any time above a cabin altitude of , and even the passengers must be provided with supplemental oxygen above a cabin altitude of . Skydivers, who are at altitude only briefly before jumping, do not normally exceed .
At altitude, the highest elevation in Bangladesh is found at Saka Haphong, in the southeastern part of the hills. Fertile valleys lie between the hill lines, which generally run north–south. West of the Chittagong Hills is a broad plain, cut by rivers draining into the Bay of Bengal, that rises to a final chain of low coastal hills, mostly below , that attain a maximum elevation of . West of these hills is a narrow, wet coastal plain located between the cities of Chittagong in the north and Cox's Bazar in the south.
A dust devil in Ramadi, Iraq. Atmospheric instability is a condition where the Earth's atmosphere is generally considered to be unstable and as a result the weather is subjected to a high degree of variability through distance and time.Stability of Air Atmospheric stability is a measure of the atmosphere's tendency to discourage or deter vertical motion, and vertical motion is directly correlated to different types of weather systems and their severity. In unstable conditions, a lifted thing, such as a parcel of air will be warmer than the surrounding air at altitude.
The alveoli are open (via the airways) to the atmosphere, with the result that alveolar air pressure is exactly the same as the ambient air pressure at sea level, at altitude, or in any artificial atmosphere (e.g. a diving chamber, or decompression chamber) in which the individual is breathing freely. With expansion of the lungs the alveolar air occupies a larger volume, and its pressure falls proportionally, causing air to flow in through the airways, till the pressure in the alveoli is again at the ambient air pressure. The reverse happens during exhalation.
Vihren seen above the forests The wildlife is alpine. The flora of Vihren's slopes consists of herbaceous plants and lichens. Vihren is home to a number of habitats, including alpine and sub-alpine open calcareous grasslands that at inclination of 30–45° at altitude over 2,500 m on the marble bedrock forms phytocenosis dominated by Sesleria korabensis, and alpine and sub-alpine closed calcareous grasslands on very rocky bedrock. With less abundance is the relict plant Carex rupestris; some plant communities have an abundance of Carex kitaibeliana and Sesleria coerulans.
Preferred habitats of this species are pools, ponds and moorlands, it is a species of still or very slow flowing water. The emerald damselfly has a large Palaeartic distribution, and is found in a band across central Europe and Asia from Spain to the Pacific. It is not found in the far north in Europe and Asia or in the extreme south, being absent from southern Spain, southern Italy and Greece. It probably occurs in some areas of north Africa; where it occurs around the Mediterranean it is found at altitude.
With the reduced aerodynamic drag at high altitude and the engine still producing rated power, a supercharged airplane can fly much faster at altitude than a naturally aspirated one. The pilot controls the output of the supercharger with the throttle and indirectly via the propeller governor control. Since the size of the supercharger is chosen to produce a given amount of pressure at high altitudes, the supercharger is oversized for low altitude. The pilot must be careful with the throttle and watch the manifold pressure gauge to avoid over-boosting at low altitude.
Antiaircraft fire was heavy and found the altitude, but was generally behind. The Japanese fighters did not dare press home their attacks, which were ineffectual. In addition to the B-17 attacks, at 07:05 the B-26's attacked through heavy fighter defense and flak with no fighter support of their own. The Marauders were equipped with external torpedo racks underneath the keel of the aircraft. The torpedo runs began at altitude, the B-26s then dropping down to only above the water under heavy attack from Japanese fighters.
Gran Canaria is known as a "continent in miniature" for its diverse landscapes like Maspalomas and Roque Nublo. In terms of its climate Tenerife is particularly interesting. The north of the island lies under the influence of the moist Atlantic winds and is well vegetated, while the south of the island around the tourist resorts of Playa de las Americas and Los Cristianos is arid. The island rises to almost above sea level, and at altitude, in the cool relatively wet climate, forests of the endemic pine Pinus canariensis thrive.
The first day of each month is shown in black, and the solstices and equinoxes are shown in green. It can be seen that the equinoxes occur approximately at altitude , and the solstices occur approximately at altitudes where ε is the axial tilt of the earth, 23.4°. The analemma is plotted with its width highly exaggerated, revealing a slight asymmetry (due to the two-week misalignment between the apsides of the Earth's orbit and its solstices). The analemma is oriented with the smaller loop appearing north of the larger loop.
Apart from these engine induced changes the NC.1071 was aerodynamically very similar to the NC.1070, with the same dimensions and only heavier empty. Its maximum speed was increased by nearly 40% at altitude and it had a greater ceiling, () but its range, much reduced, was only The NC.1071 made its first flight on 12 October 1948. It suffered damage to its undercarriage on 27 April 1949, flew again in 1950 and was modified the following May after significant structural distortion appeared in flight. Though both an all weather fighter variant (NC.
The thermal wind relation does not explain why the winds are organized into tight jets, rather than distributed more broadly over the hemisphere. One factor that contributes to the creation of a concentrated polar jet is the undercutting of sub-tropical air masses by the more dense polar air masses at the polar front. This causes surface low pressure and higher pressure at altitude. At high altitudes, lack of friction allows air to respond freely to the steep pressure gradient with low pressure at high altitude over the pole.
Boeing continued to tweak the design through the summer of 2001. Initial sketches released to the public were highly conjectural. A patent drawing filed by Boeing in early 2001 put the baseline aircraft's dimensions at approximately in length, with a wingspan of . With a delta wing and canards arrangement, and flying just short of the speed of sound at Mach 0.95-0.98 (about at altitude), the Sonic Cruiser promised 15-20% faster speed than conventional airliners without the noise pollution caused by the sonic boom from supersonic travel.
Rolls-Royce Avon; he designed the innovative multi-stage compressor He did much of the design work for R-R's compressors. In 1938 he joined Rolls-Royce Limited in Derby. While working on test beds for the Merlin engines, he proposed a variable-speed supercharger, to increase the performance at altitude, that was subsequently incorporated in the Merlin XX. He helped Stanley Hooker to design and develop the Merlin two-stage supercharger used in the Merlin 60-series. Early jet engines were being developed at Lutterworth in Leicestershire, which were having problems with surging.
The Plateau de Beille is a Zone naturelle d'intérêt écologique, faunistique et floristique [Natural Zone of Ecological Interest, Fauna and Flora] (ZNIEFF) type I. Its habitat consists of short lawns, forests of Pinus uncinata at altitude, a beech-fir forest on its lower slopes, moorland and some bogs. In the bogs are oblong-leaved sundew (Drosera intermedia), round- leaved sundew (Drosera rotundifolia) and bog club moss (Lycopodiella inundata), rare and protected species, but also the marsh cinquefoil (Comarum palustre) and tussock cottongrass (Eriophorum vaginatum).Pierre-Damien Dessarps, ibid., p.12.
The cockpit was set amidships, making it difficult to see over the long front fuselage, but otherwise visibility was good. One of its greatest advantages over the Camel was its superior performance at altitude, making it a much better match for the Fokker D.VII when that fighter arrived at the front.Cheesman 1960, p. 56. Aviation authors Donald Nijboer and Dan Patterson describe the S.E.5 as "arguably the best British-built fighter of World War I". The S.E.5 was powered by various engines, initially adopting a Hispano-Suiza 8 V8 engine.
The unusual distance of 600 m was contested in a warm-up meet two weeks before the final Olympic Trials, and Winzenried took part. He placed third to quarter-milers Lee Evans and Larry James, with Evans setting a new world best of 1:14.3; James was second in 1:14.6, and Winzenried's time of 1:14.8 was also well below the previous world best. , his time still remains the junior (under-20) world best for the distance. Like the Trials themselves, the warm-up meet was held at altitude in Echo Summit.
De Flers fell back to the fortress of Perpignan where a battalion of National Guard mutinied and had to be disbanded. Rather than pursue his beaten enemy, Ricardos turned back to invest the Fort de Bellegarde.Smith (1998), 46 A model of the fortress of Perpignan The powerful Bellegarde fortress guarded the Le Perthus pass at altitude on the main road between Barcelona and Perpignan. De Flers tried to relieve the garrison without success, including an attempt by 3,350 men to escort a supply convoy through the siege lines on 29 May.
Machair habitat in Scotland The red-billed chough breeds in Ireland, western Great Britain, the Isle of Man, southern Europe and the Mediterranean basin, the Alps, and in mountainous country across Central Asia, India and China, with two separate populations in the Ethiopian Highlands. It is a non-migratory resident throughout its range. Its main habitat is high mountains; it is found between in North Africa, and mainly between in the Himalayas. In that mountain range it reaches in the summer, and has been recorded at altitude on Mount Everest.
The most famous structures of La Palma are the minas galerias (water tunnels) which carry the water from sources in the mountains to cities, villages and farms (nowadays mainly banana plantations). La Palma receives almost all of its water supply due to the mar de nubes (sea of clouds), stratocumulus cloud at - altitude, carried on the prevailing wind which blows from the north-east trade winds. The water condenses on the long needles of the trees and other vegetation, it then either drips onto the ground or runs down the trunk etc., into the ground.
Engineers theorized that the film cassette, being lighter than the camera, might be further away, blown north by winds at altitude. FRC engineer Victor Horton organized a search and on 29 November, during the first pass over the area, Willard E. Dives found the cassette. Most puzzling was Adams' complete lack of awareness of major heading deviations in spite of accurately functioning cockpit instrumentation. The accident board concluded that he had allowed the aircraft to deviate as the result of a combination of distraction, misinterpretation of his instrumentation display, and possible vertigo.
In 1965, Colonel Beregovoy was scheduled to fly the following year in Voskhod 3, but the mission was never launched.Clark (1988). p. 182: "This mission was cancelled in late 1965; it is uncertain whether Beregovoy would have been the back-up pilot or commander for Voskhod 3." On October 25, 1968, Beregovoy took the Soyuz 3 into outer space: he orbited the Earth for almost four days at altitude up to 252 km. As part of his mission, Beregovoy twice maneuvered his craft into rendezvous positions with the unmanned Soyuz 2 satelliteClark (1988).
Gaganyaan (Sanskrit; IAST: gagan-yāna) ) is an Indian crewed orbital spacecraft intended to be the formative spacecraft of the Indian Human Spaceflight Programme. The spacecraft is being designed to carry three people, and a planned upgraded version will be equipped with rendezvous and docking capability. In its maiden crewed mission, Indian Space Research Organisation (ISRO)'s largely autonomous capsule will orbit the Earth at altitude for up to seven days with a two or three-person crew on board. The crewed vehicle is planned to be launched on ISRO's GSLV Mk III in December 2021.
It was designed to output around 1800 hp (1340 kW), or 100 hp (75 kW) per cylinder. However, the tight design of the engine made it difficult to maintain quality in manufacturing, and unreliability in the field was a significant problem; actual output of early models at altitude was in the range of 1300 hp (970 kW), far below the designed capability. Later models had improved performance, and it became one of the predominant powerplants of Japanese military aircraft in the latter part of the war. A total of 9089 were produced.
Sangin () is a town in Helmand province of Afghanistan, with a population of approximately 20,000 people. It is located on in the valley of the Helmand River at altitude, to the north-east of Lashkargah. Sangin is notorious as one of the central locations of the opium trade in the south of the country, and is also a town that has traditionally supported the Taliban.Geopium - Jane's Intelligence Review - Opiate smuggling routes from Afghanistan to Europe and Asia It was described by British newspaper The Guardian as "the deadliest area in Afghanistan" in 2010.
The Convair B-58 Hustler was a high speed strategic bomber, capable of attaining routinely Mach 2 at altitude. It incorporated a large delta wing with a leading-edge sweep of 60° and was powered by an arrangement of four General Electric J79-GE-1 turbojet engines. Although its sizable wing generated relatively low wing loading, it proved to be surprisingly well suited for low-altitude, high-speed flight. To protect against the heat generated while cruising at Mach 2, the crew compartment, the wheel wells and electronics bay were pressurized and air conditioned.
Although shown separately on maps, since the Liberation of Bulgaria in 1878 the settlement has never been registered as a populated place according to Bulgaria's official regulations. Instead it is considered a part (mahala) of the nearby village Gradets, situated 1.4 kilometers east- southeast. Beledie Han lies at altitude of 735 meters above sea level, located 11 kilometers north-northwest of the city of Kostinbrod, 18 km from Sofia Ring Road and 26 km from the center of Sofia. It is situated along Lomsko Road (Sofia – Petrohan Pass – Berkovitsa – Montana – Lom).
SOAR was a partially reusable air-launched spaceplane launch system concept designed to launch small satellites on a suborbital or orbital trajectory. The vehicle, derived from the Hermes spacecraft developed by the European Space Agency, was planned to be built, launched, and operated by Swiss Space Systems. The spaceplane was planned to launch from an Airbus A300 aircraft named S3 Zero Gravity Airliner. Once at altitude, the spaceplane was planned to separate from the aircraft and ignite an NK-39 engine developed by the Russian Federal Space Agency.
Species occur in deserts, dry washes, ditches and on rocky outcrops, including at altitude. Fagonia laevis is a perennial herb of the United States desert southwest. It has opposite leaves, trifoliate with spinescent stipules, a pink corolla and smooth fruits. Under cultivation, F. indica has been found to have a long taproot and to its growth slowing where temperatures dipped below 65 F. Commercial Fagonia products available on the web should be viewed with caution by reason of there being little to no authentication as to species contained therein, based on DNA analysis.
One of their capitals, the bull is now in the National Museum at New Delhi and the other, the lion, is at Calcutta Museum. At Nandan Garh there are also Baudh (Buddha) stupas made out of bricks and about high which according to the authoritative source are Ashoka Stupas, in which ashes of Lord Buddha’s funeral pyre are enshrined. Someshwar Fort is situated in Narkatiaganj sub-division, near Nepal border, on top of Someshwar Hill at altitude. It is in a ruined state but its remains are well defined.
The Lightnings' engines were troubled by the addition of alcohol used as an anti-knock compound in their fuel supply; a British war economy solution which caused problems with water condensation on the ground and fuel line icing at altitude. Another British attempt to correct fuel composition caused lead metal deposits to coat cylinders and foul plugs throughout the squadron. The -H series Lightnings did not have adequate cooling for extended high-power usage, as their engine development had outstripped the cooling capacity of the integral intercooler which ran through the wing's leading edge.
The pilot's open cockpit was just aft of the trailing edge, from where he could see both over the wing and through the narrow gap between wing and fuselage. The six cylinder BMW IIIa engine had a fixed pair of machine gun over it in the forward fuselage and its honeycomb radiator was in the nose, with the propeller shaft set low. This was a high compression engine which could only develop full power at altitude, enabling the J 23 to fly high and fast. Its top speed was claimed to be at but at .
282 The prototype was first flown on 11 May 1938 by the famous pilot Valery Chkalov and had its propellers replaced by constant speed VISh-61 propellers shortly afterwards. It was submitted for its State acceptance trials in October 1938Gunston, p. 306 where it proved to be faster at sea level than the VIT-1, versus , but slightly slower at altitude, at compared to at . It was recommended for production as a high-speed dive bomber provided that some of the armament was removed to increase its speed.
Aviation spirits with TEL used in WWII reached 150 octane to enable supercharged engines such as the Rolls-Royce Merlin and Griffon to reach high horsepower ratings at altitude. In military aviation, TEL manipulation allowed a range of different fuels to be tailored for particular flight conditions. In 1935 the licence to produce TEL was given to IG Farben, enabling the newly formed German to use high-octane gasoline. A company, Ethyl GmbH, was formed that produced TEL at two sites in Germany with a government contract from 10 June 1936.
The RS-27A is a liquid-fuel rocket engine developed in 1980s by Rocketdyne for use on the first stage of the Delta II and Delta III launch vehicles. It provides of thrust burning RP-1 and LOX in a gas-generator cycle. The engine is a modified version of its predecessor, the RS-27;Astronautix: RS-27 Engine its thrust nozzle has been extended to increase its area ratio from 8:1 to 12:1, which provides greater efficiency at altitude. The earlier RS-27 was derived from surplus Rocketdyne H-1 engines used in the Saturn 1B launcher.
Two out of three Progress M1-5 propulsion firings, at approximately 90 minute intervals, were used to bring the perigee of Mir down to an altitude of above the Earth's surface. A tough contact with the atmosphere occurred at altitude, when some of the external light elements of Mir were torn off due to the rush through the rarefied air. At an altitude of sufficient heating from Mir hull created a glowing halo of hot plasma. At about that time, the orbital complex broke apart and several of Mirs elements, surrounded by the plasma, were visible from Fiji against the evening sky.
In July 2014 Tiernan-Locke was banned from competition until 31 December 2015 by the UCI, resulting in his contract with the team being terminated with immediate effect. In March 2014, Sergio Henao was removed from race schedules for at least eight weeks pending the conclusion of an "altitude research programme", following tests that were taken over the winter whilst Henao was training at altitude in Colombia. In June 2014, Henao returned to racing at the Tour de Suisse, after completing an independent research programme investigating the physiology of "altitude natives" in conjunction with the University of Sheffield.
Petter later explained that the technical solution was found to lie in the right choice of wing. Swept wings had been considered, but were was found to be unnecessary at the Mach numbers attainable when carrying a useful military load with the thrust available from two contemporary turbojets. The problems that the Welkin had encountered at altitude were avoided by choosing a wing with a low aspect-ratio allowing a modest thickness/chord ratio, together with a light wing-loading. The modest curvature of the wings meant that the intersection with the fuselage and nacelles required no fillets to smooth the flow.
The EDGE displayed the ceiling or the so-called "safe-ascent-depth". A drawback was that divers faced by a ceiling did not know how long they would have to decompress, but the display featuring the saturation level of 12 tissue bars permitted experienced users to make a reasonable estimate of their decompression obligation. Orca Industries continued to refine their technology with the release of the Skinny-dipper in 1987 to do calculations for repetitive diving. They later released the Delphi computer in 1989 that included calculations for diving at altitude as well as profile recording.
Since the composition of the atmospheric air is almost constant below 80 km, as a result of the continuous mixing effect of the weather, the concentration of oxygen in the air (mmols O2 per liter of ambient air) decreases at the same rate as the fall in air pressure with altitude. Therefore, in order to breathe in the same amount of oxygen per minute, the person has to inhale a proportionately greater volume of air per minute at altitude than at sea level. This is achieved by breathing deeper and faster (i.e. hyperpnea) than at sea level (see below). Fig.
Stargazer launches Pegasus carrying the three Space Technology 5 satellites in the skies of California, 2006 Air launch to orbit is the method of launching rockets at altitude from a conventional horizontal-takeoff aircraft, to carry satellites to low Earth orbit. It is a follow-on development of air launches of experimental aircraft that began in the late 1940s. This method, when employed for orbital payload insertion, presents significant advantages over conventional vertical rocket launches, particularly because of the reduced mass, thrust and cost of the rocket. Air launching is also being developed for sub-orbital spaceflight.
Beckindale is partly demolished, and four regular characters are killed, when a Niklovic 745X wide-body airliner travelling to Canada from Eastern Europe suffers a structural failure at altitude and debris crashes into the village and surrounding countryside. The four victims of the plane crash were Mark Hughes (who had been in the show since 1988), Elizabeth Pollard (who had joined in 1990), Archie Brooks (who joined in 1983) and Leonard Kempinski (who had only joined the previous year). Five other villagers, who were not characters in the serial, were also killed, as well as all 138 passengers and crew of the airliner.
A de Havilland Sea Vixen was already airborne ready to perform the next display after the Hunter; instead it flew overhead at altitude and departed to the north. With an Avro Vulcan due half an hour later at 14:05, it was decided to let it perform a tribute flypast, after which the show was closed. All the aircraft at the airport were already grounded due to the lack of fire cover and the creation of an exclusion zone around the accident site. Following the crash, the A27 was closed in both directions, stranding those attending the airshow who had travelled by road.
It had the range to escort the USAAF bombers to the target and back again.The Mustang had been identified as early as 1942 as having the range for bomber escort duties but its engine lacked performance at altitude and in Europe the British had used it for lower level reconnaissance operations. By 1944 this had been solved by adoption of a US-built version of the Rolls-Royce Merlin. It also had the performance to engage any piston-engine German fighter in service and the firepower of six Browning AN/M2 machine guns with which to destroy them.
The J-2's thrust chamber assembly served as a mount for all engine components, and was composed of the thrust chamber body, injector and dome assembly, gimbal bearing assembly, and augmented spark igniter. The thrust chamber was constructed of thick stainless steel tubes, stacked longitudinally and furnace-brazed to form a single unit. The chamber was bell-shaped with a 27.5:1 expansion area ratio for efficient operation at altitude, and was regeneratively cooled by the fuel. Fuel entered from a manifold, located midway between the thrust chamber throat and the exit, at a pressure of more than .
Sagan kicked off the 2018 season by winning the People's Choice Classic, the prelude criterium to the Tour Down Under. Two days later, he took third place in the first stage of the 2018 Tour Down Under in a bunch sprint to Andre Greipel and Caleb Ewan. On Stage 4, Sagan maintained the pace of the lead group up Norton Summit, and was able to take his first World Tour win of the season following a descent to the finish. He skipped the Belgian season openers to prepare at altitude camp in the Sierra Nevada before starting his European campaign in Italy.
The most significant difference between the C.IV and C.VII was the choice of the Maybach Mb IVa engine to replace the Mercedes D.IV. Although the Maybach engine was around 8% less powerful than the Mercedes (when measured at the sea level), it could continue to provide most of its power output while at altitude, where power from the Mercedes engine decreased more rapidly as height increased. Other changes included wings of slightly greater area and an airscrew of larger diameter.Gray and Thetford 1962, p. 203. The crew were provided with oxygen generators and electrically-heated flight suits.
Pure aviator oxygen which has moisture removed to prevent freezing of valves at altitude is readily available and routinely used in general aviation mountain flying and at high altitudes. Most small general aviation aircraft are not pressurized, therefore oxygen use is an FAA requirement at higher altitudes. Although pure oxygen pre-breathing is an effective method to protect against altitude DCS, it is logistically complicated and expensive for the protection of civil aviation flyers, either commercial or private. Therefore, it is currently used only by military flight crews and astronauts for protection during high- altitude and space operations.
Caquot type kite balloon, used by the Allies in the mid-latter part of WWI World War I was the high point for the military use of observation balloons, which were extensively deployed by both sides. Artillery had developed to the point where it was capable of engaging targets beyond the visual range of a ground-based observer. Positioning artillery observers on balloons, generally a few miles behind the front lines and at altitude, allowed them to see targets at greater range than they could on the ground. This allowed the artillery to take advantage of its increased range.
Stage eight, the first at altitude, was taken by 's Blel Kadri, who attacked from a breakaway group with to go; he managed to hold his lead over the chasing group of overall favourites, who came in over two minutes behind. His win put Kadri into the polka dot jersey. Another solo victory came the following day, when Tony Martin of dropped fellow breakaway rider Alessandro De Marchi () with remaining. A large group that formed in pursuit of the duo finished 2 min 45 s behind, with the unconcerned general classification contenders coming together in at 7 min 46 s down.
Wind shear and mountain wave were also present at altitude. At 07:51, the crew discontinued the approach and was authorised by air traffic control to attempt an approach to the opposite runway 02. Dialogues captured by the cockpit voice recorder (CVR) suggest that the crew was receiving conflicting indications from the on board navigation instruments, but at 08:00, while continuing its descent, the crew reported to be on final approach. Around two minutes later, the CVR recorded the five hundred and minimum calls by the on-board ground proximity warning system, followed by a terrain, pull up call.
Hummingbirds can use newly- ingested sugars to fuel hovering flight within 30–45 minutes of consumption. These data suggest that hummingbirds are able to oxidize sugar in flight muscles at rates high enough to satisfy their extreme metabolic demands. A 2017 review indicated that hummingbirds have in their flight muscles a mechanism for "direct oxidation" of sugars into maximal ATP yield to support their high metabolic rate for hovering, foraging at altitude, and migrating. By relying on newly-ingested sugars to fuel flight, hummingbirds can reserve their limited fat stores to sustain their overnight fasting or to power migratory flights.
It was used on the Fokker E.IV and D.III designs. The 110 hp Oberursel UR.II, the clone of the Le Rhône 9J of the same power output, was the next major success. Fokker bought the company in 1916 in order to guarantee supplies of the UR.II. This acquisition proved advantageous because Fokker was partial to rotary powered designs, and because supplies of the Mercedes D.III engine were limited. The UR.II was used in the Fokker Dr.I and Fokker D.VI. By 1917, the UR.II had been rendered obsolete by its relatively low power and poor performance at altitude.
Reanalysis based on IMP-5 (a.k.a. Explorer 41) space solar observatory data suggests that >10‐MeV ion flux reached 70,000 cm−2 s−1 sr−1 bringing it near the exceedingly rarely reached NOAA S5 level on the solar radiation scale. Fluxes at other energy levels, from soft to hard, at >1 MeV, >30 MeV, and >60 MeV, also reached extreme levels, as well as inferred for >100 MeV. The particle storm led to northern hemisphere polar stratospheric ozone depletion of about 46% at altitude for several days before the atmosphere recovered and which persisted for 53 days at the lower altitude of .
In the 19th century, the breeder Ernest Tyssandier d'Escous set about to better the breed by selective breeding. Originally bred for work, this dual-purpose breed was especially appreciated for its ability to withstand extreme variations in temperature, its fertility, its ease of breeding, its milk (even if the presence of the calf was required to milk it), and its meat. In Cantal, the farmers practise mountain pasture, with the herd passing summer at altitude in the mountains. A female can produce almost 3,000 kg (6,614 lb) of fat-rich milk each year of her life.
During the last decades it has become evident that world records on the 1000 m for women can only be broken on (indoor) highland rinks. The last lowland record was set in 1935, the last outdoor record in 1986. Later world records were set at altitude in Calgary, and from 2002 the even higher indoor rink of Salt Lake City came into use. Monique Garbrecht was the first to skate a world record 1000 m for women there with 1:14.13, followed by Sabine Völker from Germany with 1:14.06 and Chris Witty with 1:13.83.
Thymus pannonicus, known by its common name Hungarian thyme or Eurasian thyme, is a perennial herbaceous plant, distributed in central and eastern Europe and Russia. It grows over open dry meadows, grasslands, and rocks. In Serbia, this plant species contributes to several xerothermous grass formations which develop on warm, dry silicate terrains at altitude above , mostly over plains or mild slopes, on acidic soils derived from crystalline albite-muscovite schist and gneiss-like granite. In southern Banat (Serbia), the dried herb is used to make tasty and refreshing herbal tea drinks, owing to its peculiar and pleasant lemon-like scent.
The idea of skyrunning came from Italian mountaineer Marino Giacometti and a handful of fellow climbers. They pioneered races on Mont Blanc and Monte Rosa in the early 1990s. Just months later, with the support of the Fila sportswear company, skyrunning took off across the world's mountain ranges reaching from the Alps to the Himalayas, to Mount Kenya and the Mexican volcanoes. In 1995, the Federation for Sport at Altitude was founded to address the need for rules to govern the sport and generally manage this fast-growing discipline, which today counts some 200 races worldwide with around 50,000 participants from 65 countries.
Ignition, fuel throttling, and engine operation were wrung out over a range of expected flight conditions. After a delay of two months to modify flight hardware based on ground test findings, the first powered vehicle, FFV1, was launched without incident, propelled to speeds of at altitude, roughly Mach 5.5. Over 140 inlet, combustor, and vehicle outer mold line pressure, temperatures, and vehicle accelerations as well as fuel pressure, timing feedback, and power systems monitoring were recorded. The vehicle executed the prescribed test sequences flawlessly for 15 seconds, before continuing on to splashdown into the Atlantic Ocean.
By employing thrust vectoring, the engines can direct their thrust downwards to provide additional lift during takeoff. A series of four triangular-shaped variable vanes are positioned behind the engines to provide further control authority by re-directing thrust from the rear engines over the tail fins. While cruising at altitude, propulsion can be switched to a more efficient electric drive fed from the airship's central generator. Due to the hybrid aerostatic/aerodynamic lift approach, fuel can be expended without entering a state of positive buoyancy that would necessitate routine helium venting in order to land, a costly weakness present upon conventional airships.
Seasonal trends in the appearance of new cases of Kawasaki disease have been linked to tropospheric wind patterns, which suggests wind- borne transport of something capable of triggering an immunologic cascade when inhaled by genetically susceptible children. Winds blowing from central Asia correlate with numbers of new cases of Kawasaki disease in Japan, Hawaii, and San Diego. These associations are themselves modulated by seasonal and interannual events in the El Niño–Southern Oscillation in winds and sea surface temperatures over the tropical eastern Pacific Ocean. Efforts have been made to identify a possible pathogen in air-filters flown at altitude above Japan.
It used a long range search radar to pick up targets, separate radars to track the target and interceptor missiles in flight, and a computer to calculate intercept points. The missile itself was much larger than earlier designs, with a range of up to , compared to Hercules' . To ensure a kill at altitude, where there was little atmosphere to carry a shock wave, it mounted a 400 kiloton (kT) warhead. The search radar was a rotating triangle wide, able to pick out warheads while still over away, an especially difficult problem given the small size of a typical warhead.
The mission plans were to test two unverified predictions of general relativity: the geodetic effect and frame-dragging. This was to be accomplished by measuring, very precisely, tiny changes in the direction of spin of four gyroscopes contained in an Earth satellite orbiting at altitude, crossing directly over the poles. The gyroscopes were intended to be so free from disturbance that they would provide a near-perfect spacetime reference system. This would allow them to reveal how space and time are "warped" by the presence of the Earth, and by how much the Earth's rotation "drags" space-time around with it.
The Bloch MB.174 flew for the first time in July 1939 and entered service in March 1940 with strategic reconnaissance units where it replaced the Potez 637 that had proved too vulnerable during the Phoney war. Its first operational mission was flown by the famed pilot and writer, Antoine de Saint- Exupéry, of II/33, on 29 March 1940. The Bloch 174 appeared extremely effective in these missions as its speed and manoeuvrability at altitude allowed it to escape from most modern fighters. Only three examples were lost to enemy fire during the Battle of France.

Lycoming O-320 mounted in a Robinson R22 Beta The R22 is a simple and tight design The R22 uses a horizontally mounted Lycoming O-320 (O-360-J2A on the Beta II), flat-four, air-cooled, normally aspirated, carburetor-equipped reciprocating engine. It is fueled with 100LL grade aviation gasoline. Cooling is provided through a direct drive squirrel-cage cooling fan. At sea level it is derated, or operated at less than maximum power, which has been attributed to the company wishing for the power unit to maintain the same performance at sea level as it does at altitude.
During the descent, the aircraft dived uncontrollably, attaining 690 mph (1110 km/h, Mach 0.96) before he regained control, the highest speed ever recorded for a piston- engined aircraft.Spitfire Timeline Edward Powles was awarded the Air Force Cross in June 1952. Part of his citation read: This officer, even when flying at altitude, often over the sea, alone in a single-seater aircraft, has always shown the greatest determination to complete his mission although this entailed returning to base with his fuel almost exhausted; he has repeatedly earned high praise for his skill, courage and high standard of airmanship.
In stage seven, the first at altitude, the last of the day's breakaway riders were caught with remaining, on the final climb to La Planche des Belles Filles. A select group of five – Wiggins and his compatriot and teammate Chris Froome, Cadel Evans, Vincenzo Nibali and Rein Taaramäe () – then pulled clear in the final kilometre. Evans attacked before Froome countered and went on to win the stage and take the polka dot jersey. Cancellara lost almost two minutes on the day and surrendered the yellow jersey to Wiggins, who became the fifth British rider to wear the jersey.
On 27 May 2011, the BEA released an update on its investigation describing the history of the flight as recorded by the FDR. This confirmed what had previously been concluded from post mortem examination of the bodies and debris recovered from the ocean surface; the aircraft had not broken up at altitude. but had fallen into the ocean intact. The FDRs also revealed that the aircraft's descent into the sea was not due to mechanical failure or the aircraft being overwhelmed by the weather, but because the flight crew had raised the aircraft's nose, reducing its speed until it entered an aerodynamic stall.
Scarponi then competed in the Volta a Catalunya several days later, finishing second in the overall standings behind Alberto Contador. Prior to the Giro del Trentino, Scarponi trained at altitude at Mount Etna, where his room was searched by Italian police. Scarponi won the Giro del Trentino; he broke clear with Thomas Voeckler on the final climb of the second stage, and the duo remained clear to the end, with Voeckler winning the sprint but Scarponi took the lead overall. He maintained the lead for the rest of the race, winning it for the first time.
Another overall contender involved in the crash was Chris Horner; he finished the stage, but did not start stage eight due to concussion, a nasal fracture and a hematoma to his calf. The eighth stage was the first at altitude, and saw the breakaway's only survivor, Rui Costa (), win atop Super Besse, with a twelve- second margin. Gilbert led the points classification and Tejay van Garderen () the mountains classification. In the ninth stage, there was controversy when Nicki Sørensen of was struck by a motorbike carrying a photographer, and Hoogerland and Juan Antonio Flecha () were injured after an incident with a television car.
In January 2013, Sierra Nevada announced that the second captive carry and first unpowered drop test of Dream Chaser would take place at Edwards Air Force Base, California in March 2013. The spaceplane release would occur at altitude and would be followed by an autonomous robotic landing. On 13 March 2013, NASA announced that former Space Shuttle commander Lee Archambault was leaving the agency in order to join SNC. Archambault, a former combat pilot and 15-year NASA veteran who flew on Atlantis and Discovery, will work on the Dream Chaser program as a systems engineer and test pilot.
It can reach high supersonic speeds: the aircraft is redlined at Mach 2.2 at altitude because of airframe temperature restrictions, although it is capable of higher speeds. While broadly similar to the model used on the Mirage III, the Atar engine had a greater airflow and an elevated overspeed limit from 8,400 rpm to 8,700 rpm for greater thrust during high altitude supersonic flight. While the first Mirage IV prototype was fitted with double-eyelid engine nozzles, production aircraft featured a complicated variable geometry nozzle that automatically varied in response to the descent rate and airspeed.Tangible Mirage January 1962, pp. 20–21.
Junod built a chamber in France in 1834 to treat pulmonary conditions at pressures between 2 and 4 atmospheres absolute. During the following century “pneumatic centres” were established in Europe and the USA which used hyperbaric air to treat a variety of conditions. Orval J Cunningham, a professor of anaesthesia at the University of Kansas in the early 1900s observed that people suffering from circulatory disorders did better at sea level than at altitude and this formed the basis for his use of hyperbaric air. In 1918 he successfully treated patients suffering from the Spanish flu with hyperbaric air.
In 1996, Soviet pilot Captain Igor Mentyukov claimed that, at altitude, under orders to ram the intruder, he had caught the U-2 in the slipstream of his unarmed Sukhoi Su-9, causing the U-2 to flip over and break its wings. The salvo of missiles had indeed scored a hit, downing a pursuing MiG-19, not the U-2. Mentyukov said that if a missile had hit the U-2, its pilot would not have lived. Though the normal Su-9 service ceiling was , Mentyukov's aircraft had been modified to achieve higher altitudes, having its weapons removed.
In its native range A. pataczekii grows in a cool temperate climate, however at altitude is exposed to harsh cold winds, frost and snow. It survives on a range of soils, aspects and slopes in areas that receive from 750 mm to 1500 mm of rain annually. On some sites soils are shallow and exposed to high levels of evaporation indicating drought tolerance and it has also been shown to have an efficient water transport system. It reproduces both sexually and vegetatively, freely suckering from rhizomes and the tree base following disturbance such as tree fall, animal digging and fire.
The components of all landings are the same, involving navigation from a point at altitude en route to a point where the wheels are on the desired runway. This navigation is accomplished using information from either external, physical, visual cues, or from synthetic cues such as flight instruments. At all times, there must be sufficient total information to ensure that the aircraft's position and trajectory (vertical and horizontal) are correct. The problem with low visibility operations is that the visual cues may be reduced to effectively zero, and hence there is an increased reliance on "synthetic" information.
The climate of Chipatá, at altitude, was much more pleasant than the hot lower valleys of the Opón River and Gonzalo decided to stay for five months in the town to allow his soldiers to rest and regain strength. The local Muisca of Chipatá brought the Spanish soldiers new mantles, as the ones taken from Santa Marta had worn down due to the harsh circumstances of their expedition. Some of the members of the expedition were already half-naked. In Chipatá, the Spanish for the first time learnt to drink chicha, the fermented alcoholic beverage of the Muisca.
Agioi Deka (, "Holy Ten") is a village in the Heraklion regional unit, Greece, with 861 inhabitants (2011 census). It is located in the 44th km of the Heraklion-Tympaki national road and it is the centre of the municipality of Gortyna (Δήμος Γόρτυνας). The village is built on the feet of a green hill with view to the plain of Messara, at altitude of 170 meters, over the remains of ancient Gortys. It is supposed that the cemetery of Gortys was located in this area, and many of the old houses are built using recycled material from the ruins of Gortys.
HYFLEX (Hypersonic Flight Experiment) was a National Space Development Agency of Japan reentry demonstrator prototype which was launched in 1996 on the only flight of the J-I launcher. It was a successor of OREX and was a precursor for the Japanese space shuttle HOPE-X. HYFLEX tested the carbon-carbon heat shielding tiles that were intended to be used on HOPE, as well as having the same body shaping in order to gather data on hypersonic lifting. HYFLEX flew in space at altitude and succeeded in re-entry, but sank in the Pacific after splashdown before it could be recovered.
The final report of the accident blamed it mainly on pilot error, specifically the inability to arrest the high rate of descent existing at altitude on the radar altimeter. The descent rate at touch down was . The flight data stored in the volatile memory of the aircraft's Quick Access Recorder (QAR) during the last of the approach could not be recovered due to the interruption of the power supply at impact. Probable wind variations and the loss of headwind component, together with the early retardation of thrust levers, led to a loss in indicated airspeed just prior to touchdown.
The runners lived in the Portland, Oregon area and trained at Nike's headquarters campus located just outside the Portland suburb of Beaverton, Oregon. Some of the runners in the group lived in a specially designed house where filters were used to remove oxygen from the air to simulate living at high elevation. Numerous studies have shown that living at altitude causes an athlete to develop more red blood cells, increasing athletic performance. In addition to the simulated altitude training, program was used to monitor electrodes attached to the athletes, determining what condition they were in and how far or fast they could train.
The outright record of 58.875 seconds is held by Arnaud Tournant (France), set during 2001 at altitude in La Paz, Bolivia, where Hoy also attempted to break the record. At the time, only 3 sub-60sec kilos had ever been ridden; Hoy recorded two of these over two days in La Paz. Hoy's main achievement is his development in the individual sprint event considered to be the blue riband event of track cycling. Kilo riders like Hoy have historically not fared as well at this event, as they were less experienced in the tactical elements required for the sprint.
For example, water boils at at sea level, but at at altitude. For a given pressure, different liquids will boil at different temperatures. The normal boiling point (also called the atmospheric boiling point or the atmospheric pressure boiling point) of a liquid is the special case in which the vapor pressure of the liquid equals the defined atmospheric pressure at sea level, one atmosphere.General Chemistry Glossary Purdue University website page At that temperature, the vapor pressure of the liquid becomes sufficient to overcome atmospheric pressure and allow bubbles of vapor to form inside the bulk of the liquid.
The German rookie had to wait until Round 4 in Mexico to qualify for his first race. There at the Autodromo Hermanos Rodriguez in the high altitude of Mexico City where the thinner air gave the turbos a massive power advantage over their atmospheric rivals (the 'atmos' lost a reported 25% of their power at altitude while the turbos lost around 5%), Schneider qualified in an encouraging 15th place and ran well early on the edge of the top 10 until retiring with engine failure on lap 16. The 881's replacement, the Zakspeed 891, would be powered by a Yamaha V8 engine.
Passenger oxygen mask deployment Unplanned loss of cabin pressure at altitude/in space is rare but has resulted in a number of fatal accidents. Failures range from sudden, catastrophic loss of airframe integrity (explosive decompression) to slow leaks or equipment malfunctions that allow cabin pressure to drop. Any failure of cabin pressurization above requires an emergency descent to or the closest to that while maintaining the Minimum Safe Altitude (MSA), and the deployment of an oxygen mask for each seat. The oxygen systems have sufficient oxygen for all on board and give the pilots adequate time to descend to below .
Altitude simulation systems have enabled protocols that do not suffer from the tension between better altitude physiology and more intense workouts. Such simulated altitude systems can be utilized closer to competition if necessary. In Finland, a scientist named Heikki Rusko has designed a "high-altitude house." The air inside the house, which is situated at sea level, is at normal pressure but modified to have a low concentration of oxygen, about 15.3% (below the 20.9% at sea level), which is roughly equivalent to the amount of oxygen available at the high altitudes often used for altitude training due to the reduced partial pressure of oxygen at altitude.
He was named an All-American. On March 26, 1955, on the clay and cinder track at UC Berkeley’s Edwards Stadium, Spurrier set the world’s record in the half-mile with a time of 1:47.5. Just two weeks earlier, on March 12, 1955 he had won a silver medal in the 800 at the Pan American Games in Mexico City, and ran on the gold medal winning 4×400 relay team (see Athletics at the 1955 Pan American Games). His coach, Brutus Hamilton, felt that if he could run 1:50.5 at altitude in Mexico City, that Spurrier might be able to break 1:48 at sea level in Berkeley.
By comparison, the Ares I launch consists of the immediate ignition of its single SRB first stage, then requires a staging event and ignition at altitude of its cryogenic second stage. While staging is common launch vehicle practice, it introduces safety, risk and reliability concerns, particularly on crewed flights. (The larger Jupiter-246, with its upper stage, would typically include this risk.) The DIRECT Team asserted that the Jupiter-130 and -246, with their multiple main engines, would be capable of reaching orbit even in the event of an engine shutdown. In the Jupiter concept, the crewed Orion spacecraft would be supported by a large aerodynamic fairing.
Epstein explores racial differences in sports performance and examines both nature and nurture arguments for why certain populations (such as Jamaicans and Kalenjin) are overrepresented among top performers in the 100 meters sprint and marathons respectively. Epstein examines the argument that Kalenjin tend to have a body type conducive to distance running in part due to Allen's Rule. He also explores the contribution of growing up and training at altitude, as well as the phenomenon of running to and from school. In the course of his research, Epstein followed geneticist Yannis Pitsiladis to Jamaica, where he explored folklore that Jamaican sprinters descend from a warrior class of maroons.
Power was provided by two wing-mounted Bristol Jupiter VI engines. In September 1925 the Air Ministry amended the specification, calling for superchargers on the engines, increased fuel load and a higher top speed at altitude. Barnwell attended a design conference to discuss these new demands and was told that the purpose of the aircraft was to carry a pair of Coventry Ordnance Works 37mm (1.460 in) cannon, (generally called COW guns). When Barnwell subsequently received the full details of the required equipment, which called for two Lewis guns in addition to the main armament, he realised that the aircraft would be overweight and have a landing speed of .
The AN/APS-20 was an airborne early warning, anti-submarine, maritime surveillance and weather radar developed in the United States in the 1940s. Entering service in 1945, it served for nearly half a century, finally being retired in 1991. Initially developed at Massachusetts Institute of Technology (MIT) under Project Cadillac, the radar was developed to be carried by aircraft to extend the sensor range of ships by placing a radar at altitude. Although developed for carrier-borne operation, first being installed in the single-engined General Motors TBM-3W Avenger, it was also used in larger four- engined airframes, the last being a fleet of Avro Shackleton AEW.
Park had experimented with large wings (covering the earlier Dunkirk evacuation) and insisted that they were unwieldy, difficult to manoeuvre into position and rarely in the right place when needed. The 11 Group squadrons were closer to the Luftwaffe than 12 Group and Park pointed out that there was insufficient time over Kent and Sussex for a large formation to gain altitude against the incoming raids. Bader countered by pointing out that his wing could be used as a reserve for 11 Group. Positioned well away from the Luftwaffe bases in France he could be in place at altitude when the wing was needed, providing adequate early warning was given.
The Su-24 has two Saturn/Lyulka AL-21F-3A after-burning turbojet engines with 109.8 kN (24,700 lbf) thrust each, fed with air from two rectangular side-mounted intakes with splitter plates/boundary-layer diverters. In early Su-24 ("Fencer A" according to NATO) aircraft these intakes had variable ramps, allowing a maximum speed of , Mach 2.18, at altitude and a ceiling of . Because the Su-24 is used almost exclusively for low-level missions, the actuators for the variable intakes were deleted to reduce weight and maintenance. This has no effect on low-level performance, but absolute maximum speed and altitude are cut to Mach 1.35 and .
The international judge ruled against the idea, and a scuffle ensued that involved Anquetil's manager, Raphaël Géminiani. In 1968, Ole Ritter broke the record in Mexico City, the first attempt at altitude since Willie Hamilton in 1898. The women's hour record was first established in 1893 by Mlle de Saint-Sauveur at the Vélodrome Buffalo in Paris, setting a total distance of . The record was improved several times over the next years, until Louise Roger reached in 1897 also at Vélodrome Buffalo.Revolutionary Times – The Birth of the Women’s Hour Record - SB Nation's Podium Café, Feargal McKay, 11 September 2018 In 1911, Alfonsina Strada set a new women's record of .
Empower Field carries on the tradition of the old Mile High Stadium as being one of the most difficult stadiums to play in for opposing teams. Given the difficulty of competing at altitude as well as the notoriously loud fans, the Broncos are known to have one of the best home field advantages in the NFL. Since its opening, the stadium has been home to the Denver Broncos, the Denver Outlaws lacrosse team as well as the Colorado Rapids soccer team. It has also played host to countless concerts and even served as the venue for Barack Obama's acceptance of the Democratic nomination to the Presidency.
The conversion was to be complete by February but the aircraft were not operational. Finally one machine was made ready and began operations with DB 601F engines on 30 December 1942, some ten months later. The other machine was sent to Löwenthal in July 1940 and had undergone trials with autopilot controls. From March 1941 it had been fitted with BMW 801A-1s and later A-2 engines for greater reliability on long-range sorties. In the summer of 1942 BMW 801G-1 engines were installed while later it had trials with BMW 801G-2 engines which had GM-1 boosters fitted in January 1943 for high performance at altitude.
Heike Gabriela Drechsler (; née Daute; born 16 December 1964) is a German former track and field athlete who represented East Germany and later Germany. One of the most successful long jumpers of all-time, she is a former world record holder and ranks third on the all-time list with her legal best of 7.48 metres in 1988. Her marginally wind-assisted jump of 7.63 metres (+2.1) in 1992 at altitude in Sestriere, is still the furthest a woman has ever long jumped. She is the only woman who has won two Olympic gold medals in the long jump, winning in 1992 and 2000.
2013 Nordic storms were a series of storms affecting predominantly the Nordic nations with other northern European nations also affected. The first storm in the series Hilde, named Otto by Free University of Berlin, and Eino in Finland was an extratropical cyclone affecting parts of northern Europe, causing disruption to electricity supplies and transportation across mid Norway, northern Sweden and central Finland during 15–18 November 2013. The storm brought a new record average wind speed to Sweden (at altitude), however wind speeds at lower altitudes were less than seen during Cyclone Dagmar of 2011. Most damage was caused by falling trees along the storm's path likely exacerbated by unfrozen ground.
SMES. RLVs return to land on the runway. StarTram is a proposed space launch system propelled by maglev. The initial Generation 1 facility would launch cargo only, launching from a mountain peak at an altitude of with an evacuated tube staying at local surface level; it has been claimed that about 150,000 tons could be lifted to orbit annually. More advanced technology would be required for the Generation 2 system for passengers, with a longer track instead gradually curving up at its end to the thinner air at altitude, supported by magnetic levitation, reducing g-forces when each capsule transitions from the vacuum tube to the atmosphere.
The nearly circular uninhabited island formed by Augustine Volcano is wide east-west, north-south; a nearly symmetrical central summit peaks at altitude . USGS map of Augustine Volcano island Augustine's summit consists of several overlapping lava dome complexes formed during many historic and prehistoric eruptions. Most of the fragmental debris exposed along its slopes comprises angular blocks of dome-rock andesite, typically of cobble to boulder size but carrying clasts as large as 4 to 8 meters (10 to 25 feet), rarely as large as 30 meters (100 ft). The surface of such deposits is hummocky, a field of steep conical mounds and intervening depressions with many meters of local relief.
The four J-47 turbojet engines on the B-36 were not considered JATO systems; they were an integral part of the aircraft's powerplants, and were used during takeoff, climb, and cruise at altitude. The Hercules LC-130 can be equipped with a JATO rocket system to shorten takeoff as used in the LC-130 Skibird for polar missions. During WW2 the German Arado Ar 234 and the Messerschmitt Me 323 "Gigant" used rocket units beneath the wings for assisted takeoff. Such systems were popular during the 1950s, when heavy bombers started to require two or more miles of runway to take off fully laden.
Gravity Probe B (GP-B) was a satellite-based experiment to test two unverified predictions of general relativity: the geodetic effect and frame-dragging. This was to be accomplished by measuring, very precisely, tiny changes in the direction of spin of four gyroscopes contained in an Earth-orbiting satellite at altitude, crossing directly over the poles. The satellite was launched on 20 April 2004 on a Delta II rocket. The spaceflight phase lasted until 2005; Its aim was to measure spacetime curvature near Earth, and thereby the stress–energy tensor (which is related to the distribution and the motion of matter in space) in and near Earth.
38 The northernmost group of faults on the island of São Jorge extend from Cerrado das Almas to the peak of Loiçano. But, the island is almost bisected by a fault that extends from the promontory of Rosais to just north of Calheta (in the southeast). The Rosais promontory, at a height of above sea level, an area dominated by an area of scoria cones, the highest being Monte Trigo at altitude. A final group of fractures aligned to scoria cones northwest of Velas: to the southeast there are faults towards Pico do Carvão, while to the northeast of Velas are fractures responsible for the submarine eruption in 1964.
Winzenried became a top half-miler in 1968 while a freshman at the University of Wisconsin–Madison. He placed second to Oregon Track Club's Wade Bell at the 1968 national championships in Sacramento, California, running 1:46.5, then his personal best. The United States Olympic Trials in 1968 were divided in two parts, with a semi-final meet in Los Angeles in late June and the final Trials at altitude in Echo Summit two and a half months later. Winzenried placed third behind Bell and Felix Johnson in the June meet, clocking 1:46.9; he had led at the bell in 51.5, but faded toward the end.
On August 31st, 1988, Peter Foster and Robert Mann departed Sanford Seacoast Regional Airport in a Turbo Lake Renegade, flying to a maximum altitude of 24,600 feet and then leveling off at 24,500 feet. This flight set new world records for altitude and sustained flight at altitude for single-engine amphibians, FAI class C-3C-08. A year later on November 2, 1989, two more flights departed from Bauneg Beg Lake in Sanford, Maine setting four more world records for single-engine seaplanes. In the first flight of the day, Robert Mann flew a Turbo Lake Renegade N270TL with co-pilot Gordon Collins to an of altitude 25,500 feet.
Initial testing revealed that the takeoff run was excessively long. To solve this problem, the nose elevator size was increased and the aileron up trim was interconnected with the flaps so that it operated when the flaps were lowered. On 15 November 1943, test pilot Harvey Gray, flying the first XP-55 (S/N 42-78845), was testing the aircraft's stall performance at altitude when the XP-55 suddenly flipped over on its back and fell in an uncontrolled, inverted descent. The pilot was unable to right the airplane, and it fell out of control for before Gray was able to parachute to safety.
As with other old and widespread cultivated plants it is not easy to reconstruct the original distribution and determine the borders of the past natural ranges. There are many reports concerning the earliest fossil pollen and nuts of J. regia, and the conclusions that various authors draw are somewhat contradictory. Taken together these finds suggest that J. regia possibly survived the last glaciations in several refugia, as the compilation of the data shows most likely southern Europe, the Near East, China, and the Himalaya. The largest forests are in Kyrgyzstan, where trees occur in extensive forests at altitude,Hemery 1998 notably at Arslanbob in Jalal-Abad Province .
The speed of sound (blue) depends only on the temperature variation at altitude (red) and can be calculated from it since isolated density and pressure effects on the speed of sound cancel each other. The speed of sound increases with height in two regions of the stratosphere and thermosphere, due to heating effects in these regions. Mach number is a measure of the compressibility characteristics of fluid flow: the fluid (air) behaves under the influence of compressibility in a similar manner at a given Mach number, regardless of other variables. As modeled in the International Standard Atmosphere, dry air at mean sea level, standard temperature of , the speed of sound is .
This is a list of representative R-2800 variants, describing some of the mechanical changes made during development of the Double Wasp. Power ratings quoted are usually maximum "military" power that the engine could generate on takeoff and at altitude; 100 Octane fuel was used, unless otherwise noted. The R-2800 was developed and modified into a basic sequence of subtypes, "A" through "E" series, each of which indicated major internal and external modifications and improvements, such that the "E" series engines had very few parts in common with the "A". ;Note:Suffixes such as -S14A-G denote engines developed for export to other countries.
On 18 November 2011, the first advanced hypersonic weapon (AHW) glide vehicle was successfully tested by the U.S. Army Space and Missile Defense Command as part of the Prompt Global Strike program. The missile was launched from the Pacific Missile Range Facility in Hawaii, and struck a target at the Reagan Test Site on Kwajalein Atoll, over away, in under 30 minutes. The prototype, which incorporated technologies developed by Sandia National Laboratories, was used to gather data to assist the development of future hypersonic warheads. The AHW followed an endo-atmospheric (within earth atmosphere, at altitude below 100 kilometers) non-ballistic trajectory during the test flight.
Arctic ice shrinkages of 2007 compared to 2005 and also compared to the 1979–2000 average. The North Pole is substantially warmer than the South Pole because it lies at sea level in the middle of an ocean (which acts as a reservoir of heat), rather than at altitude on a continental land mass. Despite being an ice cap, the northernmost weather station in Greenland has a tundra climate (Köppen ET) due to the July and August mean temperatures peaking just above freezing. Winter temperatures at the northernmost weather station in Greenland can range from about , averaging around , with the North Pole being slightly colder.
He also won the Kenyan Sportsman of the Year award.The Standard, 11 December 2010: Rudisha and Lagat crowned Soya best athletes With a time of 1:41.74, Rudisha set the United States all comers 800 m record at the 2012 adidas Grand Prix at Icahn Stadium in New York City. He guaranteed his selection for the Kenyan Olympic team for the first time with a win at the Kenyan trials, running a time of 1:42.12 minutes—the fastest ever recorded at altitude. Rudisha currently holds the world record of 1:40.91 for the 800 m, set at the London 2012 Olympics on 9 August 2012.
L 35, after taking part in 5 bombing raids and making 14 patrols over the North Sea, was withdrawn from combat operations in September 1917 and used for experimental flights. These included a trial in which an Albatros D.III fighter aeroplane was suspended below the ship and released at altitude: the intention was to use this to defend the airship against British seaplane patrols over the North Sea. Although the single trial, made on 25 January 1918, was successful Peter Strasser did not consider that the idea was useful unless a suitable seaplane could be developed, and the experiment was not repeated.Robinson 1971, p.
Chase view of accident based on information from the flight data recorder. During its arrival into Pittsburgh, Flight 427 was sequenced behind Delta Air Lines Flight 1083, a Boeing 727-200. At no time was Flight 427 closer than 4.1 miles to Delta 1083, according to radar data. Flight 427 was on approach at altitude, at flaps 1 configuration, and at approximately 190 knots. At 19:02:57, the aircraft entered the wake turbulence of the Delta 727 it was sequenced behind, and there were three sudden thumps, clicking sounds, and a louder thump, after which the 737 began to bank and roll to the left.
The more oxygen-rich air inside the tent is displaced and with it, the excess carbon dioxide exhaled by the occupant(s). Most athletes use altitudes between 8,000 and 15,000 feet. To cause a physiological response, the altitude must be sufficient to reduce blood oxygen saturation (sometimes measured by a pulse oximeter) to approximately 90%. In preparation to mountaineering, short-term use (1 week) of an altitude tent for overnight exposure (7.5 hours per night at 3000 m) prior to ascent to actual altitude can increase blood oxygen saturation during sleep and lessen symptoms of acute mountain sickness upon waking, but does not improve exercise performance at altitude.
This trail crosses initially the Dudh Kosi () river and a further climb leads to the Tengboche monastery at altitude. However, a down hill trek leads to Devouche, the nunnery. During the winter, the snow peaks of Ama Dablam, the tip of the Everest that glows from the Nuptse ridge and several other peaks form a picturesque landscape. Tengboche in 1974 Tengboche is a midway station on the trail to the base camp for the mountain climbers of Mount Everest and other peaks of over elevation; all these areas form part of the entire Khumbu region up to Tibet border with an area of encompassing Sagarmatha National Park.
Its main user was Led Zeppelin in the 1970s. The seating capacity was reduced and a bar with a built-in electric organ was added, along with beds, a shower, a lounge area, a TV, and video cassette player.Film The Song Remains The Same Honeywell operated the last Boeing 720 in the United States, flying out of Sky Harbor airport in Phoenix. The aircraft had been modified with an extra engine nacelle mounted on the right side of the fuselage to allow testing of a turbine engine at altitude, operating on special certification allowing it to be used for experimental use. This 720B was scrapped on June 21 and 22, 2008.
Her 100 meters time also sets the national high school record as recognized by Track and Field News, though it will not be recognized by the NFHS as the USATF Junior Championships are not a high school competition. When published (the approval process by the magazine), the 200 meter record will be notated as a "low altitude" record by T&FN.; Allyson Felix did run a faster 200 meters 22.11 at altitude in Mexico City before graduating from Los Angeles Baptist High School in 2003. Olympic gold medalist Felix is just one of the who's who of Olympians Whitney surpassed with the various records.
Tenzing Norgay had been impressive in 1935 – in future years he went on to be Sherpa many times on Everest, including on the 1952 Swiss Mount Everest expeditions. In fact he was on all the subsequent British expeditions, including 1936 and 1938, culminating in his reaching the summit of Everest in 1953. On the 1935 occasion New Zealander Dan Bryant had not been good at altitude but he had become very popular and particularly well-respected by the rest of the party. When Shipton was assembling his team for the 1951 Everest reconnaissance he received an application from an unknown New Zealander at a time when British climbers were strongly favoured.
In 1946, the de Havilland Aircraft Company conducted discussions with the British Admiralty on its requirements for a future jet-powered all-weather, radar-equipped fighter plane. From these talks, it became clear that the aircraft would need a crew of two to handle its radar and navigation equipment, as well as to fly the fighter, and that two engines were required for a safety factor over the ocean, and that swept wings were desirable. The fighter would also have a moderate wing loading for manoeuvrability at altitude and acceptable takeoff and landing performance from aircraft carriers. Highly effective wing flaps would be needed for landing and taking off.
Gagarin telegraphed "Everything is OK" despite continuing gyrations; he later reported that he did not want to "make noise" as he had (correctly) reasoned that the gyrations did not endanger the mission (and were apparently caused by the spherical shape of the reentry module). As Gagarin continued his descent, he remained conscious as he experienced about 8 g during reentry. (Gagarin's own report states "over 10 g".) At 07:55 UT, when Vostok 1 was still from the ground, the hatch of the spacecraft was released, and two seconds later Gagarin was ejected. At altitude, the main parachute was deployed from the Vostok spacecraft.
After being unable to complete the Tour de Langkawi, Danielson returned to form during the Volta a Catalunya, where he finished twelfth overall, and second in the mountains classification. Following Catalunya, Danielson finished twentieth at the Tour of the Basque Country, and offered a good showing at the Tour of California, where he took fifth place in the "queen stage" of the race, a finish at altitude at the winter ski station of Mount Baldy. He also came in ninth place in stage five's individual time trial, therefore keeping a high placing in the overall classification. These performances helped him climb to third overall.
The outstanding hydrological feature of the TTA and the surrounding Tully region is its high annual rainfall of about that is concentrated within a four-month wet-season period. The topography of TTA is moderately rugged with steep slopes rising from valley floors to the deeply bisected Walter Hill Range. These valleys lie at around elevation at the northern Downey Creek and at altitude both in the eastern Liverpool Creek sector, and the broad Jarra Creek in the southern sector of the place. All these valleys rise steeply to around where remnants of an elevated peneplain surface give way occasionally to higher peaks of around .
Deciduous woodland is the preferred habitat in the northeast The breeding habitat of the white-breasted nuthatch is woodland across North America, from southern Canada to northern Florida and southern Mexico. In the eastern part of its range, its preferred habitat is old-growth open deciduous or mixed forest, including orchards, parks, suburban gardens and cemeteries; it is found mainly in the lowlands, although it breeds at altitude in Tennessee. In the west and Mexico, this nuthatch is found in open montane pine-oak woodlands, and nesting occurs at up to altitude in Nevada, California and Mexico. Pinyon-juniper and riverside woodlands may be used locally where available.
Organisms are capable of adjusting somewhat to varied conditions such as temperature changes or oxygen levels at altitude, by a process of acclimatisation. Homeostasis does not govern every activity in the body. For instance the signal (be it via neurons or hormones) from the sensor to the effector is, of necessity, highly variable in order to convey information about the direction and magnitude of the error detected by the sensor. Similarly the effector's response needs to be highly adjustable to reverse the error – in fact it should be very nearly in proportion (but in the opposite direction) to the error that is threatening the internal environment.
A standout first season with then newly crowned A-League champions Brisbane Roar saw the 21-year-old striker included in the New Zealand squad for a friendly against China in Wuhan on 25 March 2011. Barbarouses made the 23-man All Whites squad, where played against Mexico at altitude in Denver on 2 June and against Australia in Adelaide on 5 June. Barbarouses formed part of an 18-man All Whites squad that played Jamaica in an international friendly at Mt Smart Stadium in Auckland, New Zealand on 29 February 2012. On 23 May 2012, Barbarouses scored his first goal for the All Whites in a friendly match against El Salvador.
He also won the 100 m with relative ease. There, Calvin Smith who had earlier that year set a new world record in the 100 m at altitude with a 9.93 s performance, was soundly beaten by Lewis 10.07 s to 10.21 s. Smith won the 200 m title, an event which Lewis had not entered, but even there he was partly in Lewis' shadow as Lewis had set an American record in that event earlier that year. He won the 200 m on June 19 at the TAC/Mobil Championships in 19.75 s, the second-fastest time in history and the low-altitude record, only 0.03 s behind Pietro Mennea's 1979 mark.
54 at the apex of the arc at altitude , the autopilot disengaged (this was either done by the pilots, or it disengaged automatically). Now being controlled manually, the plane began to descend to . From 18:27:01 until 18:27:09, the flight crew reported to Tokyo Area Control Center informing that KAL 007 to "descend to 10,000" [feet; 3,000 m]. At 18:27:20, ICAO graphing of Digital Flight Data Recorder tapes showed that after a descent phase and a 10 second "nose-up", KAL 007 was leveled out at pre-missile detonation altitude of , forward acceleration was back to pre-missile detonation rate of zero acceleration, and air speed had returned to pre-detonation velocity.
57, No. 1483, June 4, 1904, p. 23760-23761Carlson 2013 Tesla: Inventor of the Electrical Age, p. 209-210 Tesla believed that the entire Earth could act as an electrical resonator, and that by driving current pulses into the Earth at its resonant frequency from a grounded Tesla coil with an elevated capacitance, the potential of the Earth could be made to oscillate, creating global standing waves, and this alternating current could be received with a capacitive antenna tuned to resonance with it at any point on Earth., reprinted in Another of his ideas was that transmitting and receiving terminals could be suspended in the air by balloons at altitude, where the air pressure is lower.
A Cirrus SR20 similar to the aircraft involved in the incident The aircraft departed from Teterboro Airport in Teterboro, New Jersey, at 2:29 pm EDT (18:29 UTC). Lidle planned to fly to Nashville, Tennessee, where he had a hotel room booked for the night, then to Dallas, Texas, and finally on to his home in California. Radar measurements show that, immediately before the crash, Lidle's aircraft was flying at 112 mph (180 km/h) at altitude in the East River VFR corridor, an area which former NTSB official Peter Goelz described as "very tricky" due to its narrow width and frequent congestion. The VFR corridor ends abruptly at the northern tip of Roosevelt Island.
The conversion was fairly minor and involved an unpressurized central cabin that housed two automatic pivoting cameras, two fuel tanks and another camera fitted in the bomb bay and another camera for oblique photography was mounted in the aircraft's tail for the daylight photography role. All cameras and their viewports were electrically heated to prevent misting and icing at altitude. For night photography, the fuel tanks and camera in the bomb bay were removed and a variety of flare bombs were carried to illuminate the targets. In addition, the screen of the PSBN-M navigation radar could be photographed by a special camera and both the pilot and navigator could record their own observations using a voice recorder.
Expedition leader Eric Shipton invited Pugh, now on the High Altitude Committee of the Medical Research Council, to accompany the British 1952 Cho Oyo expedition to perform research on oxygen equipment that would be useful on the following year's expedition to Mount Everest. Pugh realised that the best way to do this was to study climbers in the field at altitude, and he analysed rates of breathing, and food and fluid intake. His report on his findings was, according to George Band, a climber on the 1953 Mount Everest expedition, of "fundamental value" to that expedition. These included the need to drink considerably more than the usual three or four pints of liquid per day; on Mount Everest.
Having been on three previous expedition with Edmund Hillary, the New Zealand mountaineer invited him in 1960–61 on a nine-month-long expedition to the Himalaya on which the long-term effects of altitude on human physiology were studied. The prefabricated "Silver Hut" was carried up to an altitude of and experiments on the cardiac and pulmonary response to a prolonged period at altitude were carried out. Here Pugh showed that Mount Everest could be climbed without oxygen, which was shown to be the case by Reinhold Messner and Peter Habeler in their ascent of 1978. Two attempts were made to climb the world's fifth-highest mountain, Makalu, () without oxygen, but they were unsuccessful.
This is also a world record for a diesel-powered engine. On April 19, 2015 Chilean Gianfranco Bianchi reached an altitude of 6,472 m (21,233 ft) with a Suzuki RMZ 450, setting the altitude record for a motorcycle. On November 6, 2017, Matthias Jeschke, again, attempted to gain two world records, one for construction at altitude and the other by beating the then current 6,688 m record.Rheinmetall MAN High Altitude Truck Expedition A refuge hut was built at 6,100 m (a record), but on December 19 it was announced the altitude record attempt had been called off at a height of 6,150 m for a combination of factors including an insurmountable rock barrier and adverse weather conditions.
This is measured as radiative forcing. While there is uncertainty about the exact level of impact of NOₓ and water vapour, governments have accepted the broad scientific view that they do have an effect. UK government policy statements have stressed the need for aviation to address its total climate change impacts and not simply the impact of CO₂.The Future of Air Transport White Paper (2003), HMSO "The aviation industry is encouraged to take account of, and where appropriate reduce, its contribution to global warming...The impact of aviation on climate change is increased over that of direct CO₂ emissions alone by some of the other emissions released and their specific effects at altitude".
The gondola line was built to provide easy access for local and foreign tourists to the Piyerloti Hill by avoiding a walk through the big Eyüp Cemetery on a hillside. At altitude, the Piyerloti Hill is named after the French naval officer, novelist and Orientalist Pierre Loti (1850–1923), who used to visit the site during his time in Istanbul. The historic Rabia Kadın Café on the top of the hill, at which he used to drink Turkish coffee, was later renamed also after him. Another establishment on the hill, of which name recalls him, is a restaurant named after his novel Aziyadé, which is the name of the main character as an Ottoman woman.
Chalk's continued to hold its FAR 121 operating with a part 298 authority in good standing, and sought to add 60-passenger regional jets to its FAR 121 operating licence, but these efforts never came to fruition. Chalk's had claimed to be the oldest continuously operating airline in the world, having begun operations in 1917 and scheduled flights in February 1919, and having only ceased operations for three years due to World War II, two days due to 1992's Hurricane Andrew, and eleven months due to an "at altitude tragedy" on December 19, 2005. The title of oldest operating airline is now given to KLM of the Netherlands, founded later in 1919.
Calvin Smith recorded a world record 9.93 seconds on 3 July 1983, again at altitude in Colorado Springs, Colorado and became the first sprinter to run under ten seconds twice, in August that year. In total, six sprinters legally broke the barrier during the 1980s. Another, Ben Johnson, had eclipsed both the 9.90 mark and 9.80 mark in 1987 and 1988; however, both of these records were disqualified after he tested positive for, and later admitted to, using steroids. The 100 m final at the 1991 World Championships represented a new zenith in the event: six athletes ran under ten seconds in the same race, and winner Carl Lewis lowered the world record to 9.86 seconds.
MESA is capable of simultaneously tracking 180 targets and conducting 24 intercepts. In addition, the radar antenna array is also doubled as an ELINT array, with a maximum range of over 850 km at altitude. The 10.8 m long by 3.4 m high antenna assembly incorporates 7.3 m long by 2.7 m high Side-Emitting Electronic Manifold array, with the top hat supporting array providing 120° coverage on port and starboard side, while the top hat array itself provides 60° fore and aft, thus providing a complete 360° coverage. The radar's beam can be set for a 2° to 8° width, while scan duration can be set from 3 s to 40 s.
The Georgia oak is native to the southeastern United States, mainly in northern Georgia, but with additional populations in Alabama, North Carolina, and South Carolina.Biota of North America Program 2014 county distribution map It grows on dry granite and sandstone outcrops of slopes of hills at altitude. Listed as Endangered (EN B1+2ce v2.3) The tree was first discovered in 1849 at Stone Mountain, Georgia, where several stands of pure specimens grow along the popular walk-up trail at around 1,300 feet (near the large chestnut oak in the middle of the trail and before the rest pavilion halfway up the trail). Georgia oaks are also found at nearby monadnocks, including Panola Mountain and Arabia Mountain in Georgia.
He later won the 1979 Summer Universiade in Mexico City where at altitude he jumped 5.60 metres. The 1980 season did not start very well as he finished only fourth at the 1980 European Indoor Championships in Sindelfingen, West Germany, the competition won by the Soviet Konstantin Volkov, who would be Kozakiewicz's main rival at the upcoming Moscow Olympics. However, in May that year at a meeting in Milan, Kozakiewicz for the first time in his career broke the world record with a mark of 5.72 metres. The record was later that summer bettered by two Frenchmen, first Thierry Vigneron added three centimetres to it and then Philippe Houvion another two, setting it at 5.77 metres.
He trained with Loel Guinness' High Adventure Company and Kittinger. The project was partially backed funded by NASA. As a part of it Bruce, Harry Taylor and scientist and astronaut Karl Gordon Henize, with an ascent team, climbed the North Ridge Route of Mount Everest in late 1993 to test a NASA meter called a "tissue equivalent proportional counter" (TEPC) at different altitudes (17,000 ft, 19,000 ft and 21,000 ft), the device measuring the effects upon the human body of radiation at altitude, which would be factored in for consideration of space missions of a longer duration. The expedition was abandoned after the death of Karl Henize from high altitude pulmonary edema on 5 October 1993.
Typical all-rocket systems peak around 450 seconds and even "typical" nuclear thermal rockets at about 900 seconds. The combination of high fuel efficiency and low-mass engines permits a SSTO approach, with air-breathing to Mach5.14+ at altitude, and with the vehicle reaching orbit with more payload mass per take-off mass than just about any non-nuclear launch vehicle ever proposed. The precooler adds mass and complexity to the system and is the most aggressive and difficult part of the design, but the mass of this heat exchanger is an order of magnitude lower than has been achieved previously. The experimental device achieved heat exchange of almost 1 GW/m3.
This engine had two chambers — the main combustion chamber as used on the earlier HWK 509A motor; but capable of just over two short tons (4,410 lbf) of thrust at full power (more at altitude), and the lower-thrust Marschofen throttleable chamber of either 300 kg (B-version) or 400 kg (C-version) top thrust levels mounted beneath the main chamber. After reaching altitude, the speed could be maintained by short bursts of the lower Marschofen cruise chamber. The question of what form of Walter 109 or 109s is not adequately addressed here. In an operational use the plane would then glide over England for a photo-reconnaissance run, descending as it flew but still at a high speed.
The first B series model was the Wasp Junior TB, which could maintain at sea level and could reach for takeoff.FAA Type Certificate Data Sheet TC 85 The TB was tuned for best performance at sea level; it was soon joined by the Wasp Junior SB, which was tuned for best performance at altitude and could sustain at altitudes up to , with available for takeoff.FAA Type Certificate Data Sheet E-123 A still later model, the Wasp Junior T1B2, had improved performance at low level, being able to sustain up to while still matching the SB's power at high altitudes.FAA Type Certificate Data Sheet TC 5E-1, see notes 5 and 6.
Monte Muambe is volcanic caldera located south-east of Moatize in Tete Province of Mozambique Morphologically, Monte Muambe is ring-shaped feature, composed of Karroo sandstones which rise from peneplain plateau at altitude between 250 m in the south and 300 m in the north. The rim of the caldera forms well-developed circular ridge of altered and indurated Karroo sandstones (gritstones) rising approximately 500 m above the plain of unaltered Karroo sediments. Due to hardness of altered Karroo sediments, after continuous, long-time erosion, Monte Muambe at present is well-developed circular ridge (caldera), basin-shaped, steep-sided and crater-like depression inside. The core of the circular structure is 200 m lower from its periphery.
Cabin of a Boeing 737 (Economy class) with typical seating arrangement The British Airways World Traveller Cabin Aircraft cabin control system on board an Airbus A319 Boeing 777-300ER operated by Biman An aircraft cabin is the section of an aircraft in which passengers travel. At cruising altitudes of modern commercial aircraft, the surrounding atmosphere is too thin for passengers and crew to breathe without an oxygen mask, so cabins are pressurized at a higher pressure than ambient pressure at altitude. In commercial air travel, particularly in airliners, cabins may be divided into several parts. These can include travel class sections in medium and large aircraft, areas for flight attendants, the galley and storage for in-flight service.
In 2008, Winglet Technology, with the help of Cessna, began flight testing epoxy/graphite elliptical winglets on a Citation X. Flight testing was nearing completion in late 2008, with FAA supplemental type certification expected in 2009. The winglets increase range by 150 nm, lower fuel burn by 4–5%, improve hot and high performance as well as climb rate, permitting a climb to flight level 430 in 22 minutes, as opposed to 26 minutes without the modification. Climb to flight level 450 at maximum takeoff weight is possible without a step climb. Cruise speed at altitude is expected to increase by 15 knots, and maximum takeoff weight will increase by 1200 lbs (545 kg).
Radinger and Otto 1999, p. 45. Regensburg delivered a total of 1,593 by the end of March 1945, after which production figures are missing. With such a high rate of production, despite continuous heavy fighting, by the end of January 1945, 314 K-4s – about every fourth 109 – were listed on hand with the first line Luftwaffe units. Ultimately it was intended to equip all Bf 109 units with the 109K, which marked the final stage of 109 development before the jet age.Zobel and Mathmann 1995, p. 43. Using MW 50 and maximum boost the Bf 109 K-4 was the fastest 109 of World War II, reaching a maximum speed of 710 km/h (440 mph) at altitude.
Three months prior to the 1972 U.S. Olympic Trials, Bacheler, along with Florida Track Club teammates Frank Shorter and Jeff Galloway, moved to Vail, Colorado to train at altitude. Each of the trio planned to compete in both the 10,000 meters and the Marathon at the Trials, which were to be held at the University of Oregon in Eugene. In the finals of the 10,000, the three FTC runners were running first, second and third, but Bacheler faltered on the final lap and (to the delight of the crowd) he was passed by a Eugene native, Jon Anderson. On the final day of the Trials, the FTC trio again dominated in the marathon.
From here, the border runs south and south-east into the High Alps, forming the western border of the Valais. It passes Les Cornettes de Bise (2431 m), Dent de Barme (2759 m), Petit Ruan (2846 m), Pointe des Rosses (2965 m), Pointe de la Fenive (2838 m), and Le Cheval Blanc (2830 m), placing Lac du Vieux Émosson in Switzerland. From Grand Perrond (2672 m), the border descends to 1130 m, crossing the Martigny-Chamonix road, before ascending to Les Grandes Otanes (2656 m), Aiguille du Tour (3541 m), Aiguille d'Argentiere (3898 m), Tour Noir (3837 m) and finally to the tripoint with the French-Italian and Swiss-Italian borders, at a point just west of Mont Dolent, , and at altitude.
Having not made the grade as a downhill skier, he switched to ski jumping as there were no other British ski jumpers with whom to compete for a place. Edwards began jumping under the eye of John Viscome and Chuck Berghorn in Lake Placid, New York, using Berghorn's equipment, although he had to wear six pairs of socks to make the boots fit. He was disadvantaged by his weight—at about 82 kg (181 lb, 12st 13lb), more than 9 kg (20 lb) heavier than the next heaviest competitor—and by his lack of financial support for training, being totally self-funded. Another problem was that he was very farsighted, wearing thick glasses under his goggles, which would mist up at altitude.
The Bolivian Navy had a history of diving in the lake and wished to keep up to date its understanding of the technical and medical aspects of diving at such extreme altitudes. The purpose of Exercise Paddington Diamond was to work with the navy to test under field conditions the latest generation of dive computers and the high altitude decompression algorithms they used. In line with this objective Professor Albert Bühlmann of the University of Zürich, the world's leading expert on diving at altitude, provided the expedition with new decompression tables for diving up to 4,500m above sea level. Through Professor Bühlmann's contacts with Swiss instrument manufacturers the expedition's two models of diving computer were pre- programmed with these latest calculations.
By 1916, the cost of Goddard's rocket research had become too great for his modest teaching salary to bear. He began to solicit potential sponsors for financial assistance, beginning with the Smithsonian Institution, the National Geographic Society, and the Aero Club of America. In his letter to the Smithsonian in September 1916, Goddard claimed he had achieved a 63% efficiency and a nozzle velocity of almost . With these performance levels, he believed a rocket could vertically lift a weight of to a height of with an initial launch weight of only .. (Earth's atmosphere can be considered to end at altitude, where its drag effect on orbiting satellites becomes minimal.) The Smithsonian was interested and asked Goddard to elaborate upon his initial inquiry.
They also broke the world record which had been set by the British in 2013 at altitude in Aguascalientes City by nearly three seconds. She subsequently described this performance as the defining result of her career. She returned to the Olympic Games as part of the Australian team in the team pursuit at the 2016 Summer Olympics: the team entered the Olympics as one of the expected challengers for the gold medal, however they suffered a setback three days before the start of competition when four of the team's five selected riders - Hoskins, Ashlee Ankudinoff, Amy Cure and Georgia Baker - crashed when training on the Rio Olympic Velodrome. Although she avoided major injury, Hoskins was on crutches until the eve of the qualifying round.
TOC establishes a "starting gate" for the en route portion of a flight to allow timing and tracking along the course. A clearly determined TOC is predicated in planning along the intended route of flight far enough from the departure so that the aircraft is at altitude, on course, trimmed up in cruise flight. The variability of departure is now over and accurate tracking and monitoring of progress are beginning. Use of TOC/TOD in VFR flight planning Once past TOC (and by definition stabilized on course) a pilot can efficiently ascertain whether the wind and weather are "as forecast" and the groundspeed attained will allow for the safe completion of the flight "as planned" or within an acceptable margin for safety.
The 9th RW has been the host unit at Beale to the current day. With the activation of the 9th SRW at Beale, the wing absorbed the assets of the provisional 4200th SW. This allowed it to stay with the 14th Strategic Aerospace Division. The wing performed strategic reconnaissance in Southeast Asia beginning in 1968, frequently deploying the SR-71 to Kadena Air Base, Okinawa where it operated over areas of the Pacific and Asia. The wing provided photographic intelligence for the Son Tay prison camp raid named Operation Ivory Coast, in North Vietnam, November 1970. After the Vietnam War, the SR-71 established a level-flight-at-altitude record at 85,131 feet and a straight-course speed record of 2,194 mph.
Subsequent turbos take the charge from the previous stage and compress it further (for example to an additional three times intake pressure, for a total boost of nine times atmospheric pressure). A downside of staged turbocharging is that it often leads to large amounts of turbo lag, therefore it is mostly used on piston engine aircraft which usually do not need to rapidly raise and lower engine speed. (and thus where turbo lag is not a primary design consideration), and where the intake pressure is quite low due to low atmospheric pressure at altitude, requiring a very high pressure ratio. High-performance diesel engines also sometimes use this configuration, since diesel engines do not suffer from pre-ignition issues and can therefore use high boost pressures.
Aircraft altimeters measure the relative pressure difference between the lower ambient pressure at altitude and a calibrated reading on the ground. In the United States, CanadaFrom the Ground Up - 29th Edition and Japan, these altimeter readings are provided in inches of mercury, but most other nations use hectopascals. Ground readings vary with weather and along the route of the aircraft as it travels, so current readings are relayed periodically by air traffic control. Aircraft operating at higher altitudes (at or above what is called the transition altitude, which varies by country) set their barometric altimeters to a standard pressure of 29.92 inHg (1 atm = 29.92 inHg) or 1013.25 hPa (1 hPa = 1 mbar) regardless of the actual sea level pressure.
This bird is often the most numerous or only vulture present in primary lowland forests in its range, but in the Amazon rainforest it is typically outnumbered by the greater yellow-headed vulture, while typically outnumbered by the lesser yellow-headed, turkey and American black vulture in more open habitats. King vultures generally do not live above , although are found in places at altitude east of the Andes, and have been rarely recorded up to They inhabit the emergent forest level, or above the canopy. Pleistocene remains have been recovered from Buenos Aires Province in central Argentina, over south of its current range, giving rise to speculation on the habitat there at the time which had not been thought to be suitable.
Lewis was in the lead through four rounds: his first round jump of 8.68 set a new championship record, then his third round jump set his then personal record, albeit wind assisted at 8.83w. Mike Powell's fourth round jump looked like it was in the range of Lewis, but was ruled a foul. The closeness of the call upset Powell: he went down to his knees at the board trying to see the microscopic indentation into the plasticine indicating it was a foul. Lewis' fourth round jump was wind-aided, but, at 8.91w m, it was the longest ever competition long jump in history, beating the existing wind-legal world record set by Bob Beamon at altitude at the 1968 Summer Olympics.
When the engine is shut down at altitude, the core begins to cool, and the stator, including the static interstage static seal (ISS), contracts at a faster rate than the adjacent rotating parts in both the radial and axial direction because of its smaller thermal time constant. The relative rate of cooling of the stator and rotor results in an alignment of the rotating-seal knife edges aft of the normal operating groove in the static seal. If the clearances are tight enough and the relative cooling rates are right, contact can occur between the static and rotating seal elements. The resulting stiction can temporarily prevent the rotor from turning when only the force of ram air is applied to the core.
Hikers and mountain climbers use wrist-mounted or hand-held altimeters, in addition to other navigational tools such as a map, magnetic compass, or GPS receiver. The calibration of an altimeter follows the equation :z=c\;T\;\log(P_o/P), where c is a constant, T is the absolute temperature, P is the pressure at altitude z, and Po is the pressure at sea level. The constant c depends on the acceleration of gravity and the molar mass of the air. However, one must be aware that this type of altimeter relies on "density altitude" and its readings can vary by hundreds of feet owing to a sudden change in air pressure, such as from a cold front, without any actual change in altitude.
The bank, just off Bermuda, was of particular interest at the time to the Navy's Project Artemis in which an initial installation of a horizontal and a vertical string of hydrophones were installed during 1961. A unique opportunity came on 14 November 1963 when the volcanic island of Surtsey emerged off Iceland when a project aircraft was in the area to fly a survey of the emerging island at altitude. During July 1966 the dormant island was resurveyed revealing a magnetic anomaly not evident in the original survey. By the late 1980s the RP-3D Project Magnet aircraft, specially built using nonmagnetic materials aft of the main cabin door, was named Roadrunner and had the distinctive squadron livery of international orange and white.
In Alaungdaw Kathapa National Park, it was also recorded in a close tall forest in 1999. In Thailand, small Indian civets were recorded in Kaeng Krachan and Khao Yai National Parks, in evergreen gallery forest of Thung Yai Naresuan Wildlife Sanctuary, in secondary and dipterocarp forest of Huai Kha Khaeng Wildlife Sanctuary, and in Phu Khieo Wildlife Sanctuary at altitude in deciduous forest. In Laos, small Indian civets were recorded in a variety of habitats including semi-evergreen and deciduous forest, mixed deciduous forest, bamboo forest, scrubby areas, grasslands and riverine habitat. In Cambodia's Cardamom Mountains, small Indian civets were recorded in deciduous dipterocarp forests, often close to water bodies and in marshes during surveys conducted between 2000 and 2009.
Elevate is a service provided to lift payloads to near space on a stratospheric balloon platform for purposes such as testing of (components of) spacecraft, drop tests, celestial observation or publicity. The useful load on a stratospheric zero pressure balloon can range from several kilograms to over 5000 kg and the target altitude varies between 20 and 42 kilometers. The duration at altitude or ‘float’ can be extended from hours to several days or even weeks depending on the launch location. Additional solutions such as solar arrays, battery power or advanced return options such as a guided parafoil (as opposed to a traditional parachute) and tailor-made solutions to customer requirements are also offered as part of the Elevate service.
A 4WD track goes up from the national park entrance to a carpark at altitude on north side, just below the José F. Ribas Refuge. This stone mountain hut — owned and operated by Grupo Ascensionismo del Colegio San Gabriel — is situated higher at (a 40-80 minute uphill hike). Here climbers can spend the night and begin their summit bid in the early morning without any intermediate camps. (Typically no more than about half of those attempting to summit Cotopaxi make it to the top after a daunting — though non-technical — six-hour scramble.) Summiting normally starts around 12:30 am, to reach the summit at latest 7:30 am and then return to the hut before the snow melts and glacier crevasses move/evolve.
On December 23, Istomin abandoned his position and moved towards Ardahan. Hafız Hakkı sent two divisions to pursue Istomin. At the extreme left wing, the Stange Regiment, which had landed at Trabzon, was to move up the Çoruh valley towards Ardahan and through a pass at altitude. On December 23, the 92nd Regiment of the Turkish 31st Division, believing the unit in front of them to be Russians, opened fire on the flank of the 32nd Division. The ensuing four-hour friendly fire battle in the fog killed 2,000 Turkish soldiers, and wounded many more.Olcen, Mehmet Arif, Vetluga Memoir,(Gainesville: University Press of Florida, 1995),21. Allahüekber Mountains On December 24, Hafız Hakkı was well beyond Oltu after having marched in just over three days.
The evergreen broadleaf trees' zone is gradually replaced by ecosystems of European black pine, that forms compact clusters, with no intermediate zone of deciduous oaks, although trees of these species occur sporadically within clusters of black pine. On the northern slopes of Xirolakos valley, at altitude between 600 and 700 metres, there is a high forest of downy oak of about 120 hectares. The black pine dominates on the eastern and northern side of the mountain, between 500 and 1,700 metres. In this zone there is also hybrid fir in small groups and scrubs or small clumps, particularly in the lower region and in the sites Naoumi (west) and Stalamatia and Polykastro (east), where it is mixed with black pine and Bosnian pine.
The crash occurred when an incorrectly secured cargo door at the rear of the plane burst open and broke off, causing an explosive decompression that severed critical cables necessary to control the aircraft. To maximize the working space within the cargo hold, the cargo doors opened outwards, leading to the possibility of them being forced open at altitude under normal in-flight pressure. To prevent this, a special latching system was used that locked shut under pressure when properly closed. To ensure the latches were properly positioned, a handle on the outside of the door pressed small metal pins into the latches; if the latches were in the improper location the pins would not align and the handle would not close.
However, thanks to Scott's decision to conduct the tests at altitude, he was able to "trim [the R36] and...bring her safely to earth" by moving crew members about within the hull. Scott was also involved in the R36's high- profile 14 June 1921 flight over the Ascot Races, with journalists and Metropolitan Police representatives aboard, to assess the airship's potential role in road-traffic control. However, just a week after the Ascot flight, the R36's career was ended by severe damage to its bows resulting from a landing accident at Pulham. After taking over command from the ship's captain, Flight Lieutenant Herbert Irwin (later captain of the R101), Scott conducted an excessively rapid approach to the mast.
In the Leyland Bus book Doug Jack makes mention of a model built only by Bus Builders, this variant was known as the SA2. Eighty of these were built for South African Railways (SAR) in the 1960s. SAR, operating buses in difficult terrain and often at altitude, required very high power outputs for the time and wanted more than the 200 bhp available from the Leyland O.680H, presumably the 15.2 litre Leyland-Albion O.900H was not suitable for the application, or had ceased production, as the SA2 Olympic featured a 220 bhp Cummins engine coupled to Twin-Disc torque-converter transmission. Some of these were 6x4 versions with non-reactive rear suspension as on Leyland-group goods models of the time.
Ned Overend, John Tomac and Tinker Juarez Compete in the Cindy Whitehead Desert Classic, Palm Springs, California, 1989 - Photo by Patty Mooney Even though he retired from professional mountain bike competition in 1996, he continued competing in endurance competitions, winning the XTERRA Triathlon in 1998 and 1999 and competing in regular road triathlons. He won the U.S. National Winter Triathlon Championship in 2000 and the UCI Masters Cyclo-cross World Championship in 2012. In 2015, Overend won the first-ever U.S. Fat Bike championship. During his professional mountain biking career, Overend earned the nicknames "Deadly Nedly" and "The Lung", because he was very difficult to beat and for his exceptional aerobic endurance at altitude (especially so for a man of his age), respectively.
With Nepal still closed to climbers, the approach was again to be from the north side of the mountain. Above the North Col a few routes had been prospected on the 1922, 1924 and 1933 expeditions and a full-scale expedition (the largest yet) was again to be embarked upon. Long afterwards Shipton wrote The rancorous arguments within and surrounding the Everest Committee preceding the 1935 reconnaissance had led to Shipton replacing Hugh Ruttledge for that one expedition but Ruttledge was confirmed as leader for 1936. Bill Tilman and Dan Bryant had not acclimatised well at altitude and so were not included in the party - both men agreed this was the right decision, Tilman even to the extent of providing financial support.
The significance of the thick wing section may not have been understood by Petterbecause compressibility effects had only started to be encountered by aircraft designers.Roland Beamont states that George Bulman was probably the first pilot among the allied nations to describe the effects of compressibility on aircraft handing in a memorandum at Langley in 1943 During test flying the effect of compressibility was experienced by Penrose who wrote, "In speed runs at the ceiling the wings and fuselage sometimes shook as though the machine was bumping over cobblestones." Petter was reluctant to believe Penrose or accept that the wing would not be acceptable for high speed at altitude. Welkin Mark I, DX318, in flight While the cabin pressurisation was innovative and worked well, the heat from the compressor 'was like sitting in an oven'.
Chute-Garneau Location of the course of the Chicoutimi River in the borough Chicoutimi The Chicoutimi River rises at Portage-des-Roches, in the Laterrière sector of the Chicoutimi borough at altitude and flows northeast towards Laterrière-Bassin where it is spanned by the Père-Honorat bridge. Leaving the rocky base and the steep relief of Portage-de-Roches, it then enters an alluvial and semi-alluvial plain up to dam de la Chute-GarneauGR Brooks, DE Lawrence, page 285 where the landscapes on both banks alternate between residences and agricultural land for a little over ten kilometers. The Chute-Garneau dam is a watercourse retaining structure located on a rock base. Half a kilometer further on, route 170 crosses the river which then enters a more urbanized sector of the Chicoutimi borough.
At those same Olympics, Greene took the bronze medal and all three teamed with Mel Pender to win the gold medal in the 4x100 m relay in world record time. Over the next eight seasons, before the IAAF changed their record criteria, six more individuals tied the 9.9 hand timed world record. The automatic 9.95 was not surpassed until 1983, when Calvin Smith ran 9.93, again at altitude, at the U.S. Air Force Academy near It is worth noting that Bob Hayes was timed at 9.9 seconds four years earlier in the final of the 100 metres at the 1964 Olympics in Tokyo. The official time was given as 10.0 seconds because of an idiosyncratic method of measuring the 'hand' times which was only used at that Olympics.
Doubling the volume of the lungs halves the pressure in the lungs at any altitude. Having the sea level air pressure (100 kPa) results in a pressure gradient of 50 kPa but doing the same at 5500 m, where the atmospheric pressure is 50 kPa, a doubling of the volume of the lungs results in a pressure gradient of the only 25 kPa. In practice, because we breathe in a gentle, cyclical manner that generates pressure gradients of only 2–3 kPa, this has little effect on the actual rate of inflow into the lungs and is easily compensated for by breathing slightly deeper. The lower viscosity of air at altitude allows air to flow more easily and this also helps compensate for any loss of pressure gradient.
The writing was generally above the standard for contemporary half-hour programs, although sometimes critics suggested that the acting was not. Later episodes of the television show were notable for the dramatic opening with an air-to-air shot of the sleek, second Songbird banking sharply away from the camera and its engines roaring, while the announcer proclaimed, "Out of the blue of the Western sky comes Sky King!" The short credit roll which followed was equally dramatic, with the Songbird swooping at the camera across El Mirage Lake, California, then pulling up into a steep climb as it departed. The end title featured a musical theme, with the credits superimposed over an air-to-air shot of the Songbird, cruising at altitude for several moments, then banking away to the left.
Gerry Bull and other BOAC engineers examined the aircraft for Flight 201. Previously, the same team had examined BOAC Flight 781 (a Comet that had broken up at altitude in January 1954) prior to its final flight."Comet Air Crash" ("Crash of the Comet"). Seconds From Disaster. Flight 201 took off from London for Rome at 13:00 UTC on Wednesday 7 April 1954, on the first leg southward to Johannesburg, arriving at Rome approximately two and a half hours later, at 17:35 UTC. On arrival at Rome, engineers discovered some minor faults, including a faulty fuel gauge and 30 loose bolts on the left wing, which delayed the aircraft's departure by 25 hours before Yoke Yoke was ready to depart for Cairo on the evening of Thursday 8 April.
Ireland travelled to South Africa in June 2004, having won their first Triple Crown since 1985, and beaten the champions of the 2003 Rugby World Cup, England in their first home game since the final. As a result, the Irish manager, Eddie O'Sullivan, was confident that Ireland would achieve their first win over South Africa in 39 years, their only previous victory having come in Dublin in 1965. By contrast, South Africa had just changed their coach to Jake White and he had radically changed the team for his first test since taking charge of the Springboks. The first of the two game test series was played at altitude in Bloemfontein and South Africa eventually won the match 31-17, despite the scores being level at 11-all at half time.
The Sherpa are able to make much more money acting as travel guides due to their local knowledge, and climbing ability. Genetic evidence suggests that the Tibetan peoples diverged from the larger Han Chinese population any time around 1,000 B.C.E. to 7,000 B.C.E. Given the significant mutations to the EPAS1 gene that contribute to the Tibetan resistance to altitude sickness, this suggests that the extreme evolutionary pressure on the Tibetan peoples has produced one of the fastest natural selection effects seen in a human population. The adaptations of Tibetans to their hypoxic ventilatory response interact with other adaptations to promote successful reproduction. For example, Tibetans have evolved a greater oxygen saturation during infancy, leading to a lower rate of child mortality than experienced by non-adapted populations at altitude.
During its trials on 16 January 1941, W4050 outpaced a Spitfire at . The original estimates were that as the Mosquito prototype had twice the surface area and over twice the weight of the Spitfire Mk II, but also with twice its power, the Mosquito would end up being faster. Over the next few months, W4050 surpassed this estimate, easily beating the Spitfire Mk II in testing at RAF Boscombe Down in February 1941, reaching a top speed of at altitude, compared to a top speed of at for the Spitfire. On 19 February, official trials began at the Aeroplane and Armament Experimental Establishment (AAEE) based at Boscombe Down, although the de Havilland representative was surprised by a delay in starting the tests.Sharp and Bowyer 1971, pp. 44–45.
All Comet 1 aircraft were grounded in April 1954 after four Comets crashed, the last two being BOAC aircraft at altitude. Later jet airliners including the larger and longer-range Comet 4 were designed to be fail-safe: in the event of for example a skin-failure due to cracking the damage would be localized and not catastrophic. On 4 October 1958, BOAC started transatlantic flights between London Heathrow and New York Idlewild with a Comet 4, and Pan Am followed on 26 October with a Boeing 707 service between New York and Paris. Supersonic flights on the Concorde were offered from 1976 to 2003, from London (by British Airways) and Paris (by Air France) to New York and Washington, and back, with flight times of around three and a half hours one-way.
F/A-18 Super Hornet. F-4 Phantom shown from an ATFLIR Targeting Pod The AN/ASQ-228 Advanced Targeting Forward-Looking Infrared (ATFLIR) is a multi- sensor, electro-optical targeting pod incorporating thermographic camera, low- light television camera, target laser rangefinder/laser designator, and laser spot tracker developed and manufactured by Raytheon. It is used to provide navigation and targeting for military aircraft in adverse weather and using precision-guided munitions such as laser-guided bombs. It is intended to replace the earlier AN/AAS-38 Nite Hawk pod in US Navy service. ATFLIR is 72 in (183 cm) long, weighs 420 lb (191 kg), and has a slant range of 40 mi (64.3 km), said to be useful at altitude of up to 50,000 ft (15,240 m).
Pre- race favourites were Nao Kodaira, world record holder at this distance and winner of every single pre-Olympic ISU World Cup 500m in the 2017/18 season, and Lee Sang-hwa, two-time Olympic 500m gold medallist. Skating in the fourth pair, Jorien Ter Mors posted a time of 37.53, which stood until Brittany Bowe improved it by 0.009 seconds in the eleventh pair. Starting in pair 16 versus Karolína Erbanová, Japan's Nao Kodaira raced to an Olympic and sea-level record of 36.94, clocking an unprecedented lap time of 26.68 - a pace for the longest time deemed "impossible" even at altitude (which Gangneung is not). In pair 15, South Korea's Lee Sang-hwa opened faster than Kodaira and was up two tenths in back straight intermediate timings.
The people were very religious and honoured their two main deities Sué, the Sun, and Chía, his wife; the Moon in their Sun and Moon temples in Sugamuxi and Chía respectively. Each small settlement of maximum 100 bohíos was headed by a cacique and the major towns of Bacatá and Hunza were ruled by the zipa and zaque. The Sacred City of the Sun Sugamuxi was ruled by a priest, called iraca and the northernmost area headed by the Tundama based in the hills around the former lake of Duitama. The initiation ritual of the new zipa took place in their sacred Lake Guatavita where he would cover himself in gold dust and jump from a raft in the waters of the circular lake at altitude, a ritual represented in the famous Muisca raft.
Deployment of the constellation was not then projected until "late in this decade or early in the next". In November 2016, SpaceX filed an application with the Federal Communications Commission (FCC) for a "non-geostationary orbit (NGSO) satellite system in the Fixed-Satellite Service using the Ku and Ka frequency bands". In March 2017, SpaceX filed plans with the FCC to field a second orbital shell of more than 7,500 "V-band satellites in non- geosynchronous orbits to provide communications services" in an electromagnetic spectrum that has not previously been heavily employed for commercial communications services. Called the "Very-Low Earth Orbit (VLEO) constellation", it would comprise 7,518 satellites and would orbit at just altitude, while the smaller, originally - planned group of 4,425 satellites would operate in the Ka \- and Ku-bands and orbit at altitude.
The lake level would have peaked from 16,000 to 14,500 years ago at altitude. Shortly before 14,200 BP, the lake level would have begun its drop to by 13,800 BP. The Coipasa phase began before 13,300 BP and reached its peak at 12,500 years ago. The Coipasa lake's regression was nearly complete around 11,500 years ago. Lake Tauca is sometimes subdivided into three phases (Lake Tauca proper, Ticaña and Coipasa), with the Tauca phase lasting from 19,100 to 15,600 BP. The Coipasa phase, originally thought to have lasted from 11,400 and 10,400 BP, was corrected to 9,500 to 8,500 BP. During this phase, lake levels rose to altitude and the depth of the lake reached . According to a 1998 publication, Lake Tauca and the Coipasa phase lasted from 15,000 to 8,500 BP. The Coipasa phase has also been identified in Lake Chungará.
Taking off from Newfoundland, he nearly reached the Azores before heavy fog caused loss of the horizon, making flying in the early aircraft extremely dangerous. What appeared to be fairly calm seas at altitude turned out to be a heavy chop, and a control cable snapped while setting the aircraft down. Mitscher and his five crewmen were left to sit atop the upper wing of their "Nancy" while they waited to be rescued. Of the three aircraft making the attempt, only NC-4 successfully completed the crossing. For his part in the effort Mitscher received the Navy Cross, the citation reading: > "For distinguished service in the line of his profession as a member of the > crew of the Seaplane NC-1, which made a long overseas flight from New > Foundland to the vicinity of the Azores, in May 1919".
The legacy of the David Dunlap Observatory continues in the Dunlap Institute for Astronomy & Astrophysics, a research institute at the University of Toronto established in 2008. The DDO is the site of a number of important studies, including pioneering measurements of the distance to globular clusters, providing the first direct evidence that Cygnus X-1 was a black hole, and the discovery that Polaris was stabilizing and appeared to be "falling out" of the Cepheid variable category.Polaris - The Story Continues Photoelectric Photometry Newsletter, American Association of Variable Star Observers, May 1998 Located on a hill, yet still relatively close to sea level at altitude, and now surrounded by subdivisions, its optical astronomy ability has been reduced as compared to other remote observatory sites around the world. On July 31, 2019, the DDO was announced as a National Historic Site of Canada.
He investigated the implications of decompression after diving at altitude and published decompression tables that could be used at a range of altitudes. Bühlmann used a method for decompression calculation similar to that proposed by Workman, which included M-values expressing a linear relationship between maximum inert gas pressure in the tissue compartments and ambient pressure, but based on absolute pressure, which made them more easily adapted for altitude diving. Bühlmann's algorithm was used to generate the standard decompression tables for a number of sports diving associations, and is used in several personal decompression computers, sometimes in a modified form. B.A. Hills and D.H. LeMessurier studied the empirical decompression practices of Okinawan pearl divers in the Torres Strait and observed that they made deeper stops but reduced the total decompression time compared with the generally used tables of the time.
Edward Abbott and Leslie Baynes had already separately designed and built sailplanes when they joined forces in 1931 as Abbott-Baynes Sailplanes to produce Baynes' Scud I and II designs. The idea of adding an engine to a sailplane to make it self-launching, but mounted in such a way that propeller and engine could be retracted at altitude to produce an aerodynamically clean glider came from Sir John Carden, who had already collaborated with Abbott and Baynes on other projects. Baynes' Scud 3 was designed specifically to include such a launching aid but was also capable of high performance engineless flight. Without an engine it was known as the Abbott-Baynes Scud 3; with the engine, as the Carden-Baynes Auxiliary.Flight 9 May 1935 p.508-9 Since the engine could be removed or retrofitted the nomenclature sometimes became confused.
The captain chose to fly with visual flight rules. Other aircraft that passed through the accident area after Widerøe Flight 933 experienced strong turbulence between and Aircraft use feet as the unit of measure for altitude instead of meters in altitude.Parliament: 22 On 11 March 1982 the Twin Otter left Berlevåg at 13:19 - 11 minutes early, thus causing one passenger to miss the flight. The first officer reported to Mehamn Aerodrome Flight Information Service (AFIS) at 13:22 that the aircraft was at altitude over the Tanafjord and had an estimated time of arrival of 13:33. Radio contact ended at 13:22:53. The flight path was monitored by an officer at the Royal Norwegian Air Force (RNoAF) control and reporting center in Honningsvåg between 13:23:20 and 13:25:25, after which the aircraft no longer appeared on radar.
Delta 3914 rocket carrying the GOES-G satellite was destroyed by range safety 71 seconds after launch due to an electrical failure. In the field of rocketry, range safety may be assured by a system which is intended to protect people and assets on both the rocket range and downrange in cases when a launch vehicle might endanger them. For a rocket deemed to be off course, range safety may be implemented by something as simple as commanding the rocket to shut down the propulsion system or by something as sophisticated as an independent Flight Termination System (FTS), which has redundant transceivers in the launch vehicle that can receive a command to self-destruct then set off charges in the launch vehicle to combust the rocket propellants at altitude. Not all national space programs use flight termination systems on launch vehicles.
The title refers to a dropsonde, a device designed to be dropped at altitude by parachute to collect data as the device falls to the ground (on Earth or sent to another planet.) A Dropsonde sampler was pre- released on vinyl as a mini album on 27 September 2005 and the full album released on compact disc in January 2006 (though the track "In the Shape of a Flute" remained exclusive to the vinyl sampler). Unlike Jenssen's previous output, there is a notable jazz influence present on this album (such as on the tracks "Birds Fly By Flapping Their Wings" and "In Triple Time"), evocative of Miles Davis's 1970s jazz fusion works.Cf. the Allmusic review. Some tracks also integrates material Jenssen recorded in late 2001 during his climbing of the 8,201 meters mount Cho Oyu in Himalaya.
The Germans also experimented with the idea, suspending an Albatros D.III fighter aeroplane below a Zeppelin and releasing it at altitude: the intention was to use the aeroplane to defend airships against the British seaplane patrols encountered over the North Sea. Although the single trial, made on 25 January 1918, was successful the experiments were not continued. On 12 December 1918, in a test to determine the feasibility of carrying fighter aircraft on dirigibles, the airship C-1 lifted a US Army Curtiss JN-4 aircraft to 2,500 feet over Fort Tilden, New York, and at that height released it for a free flight back to base. The airship was piloted by Lieutenant George Crompton, Dirigible Officer at NAS Rockaway, and the airplane by Lieutenant A. W. Redfield, USA, commander of the 52nd Aero Squadron based at Mineola (Long Island, NY).
The US Naval Air Systems Command intends to award Rolls Royce two contracts to examine the effectiveness of proposed reliability improvements, the first is a software tweak to the engine management software for the compressor guide vanes that internal testing showed could improve surge margin by 0.8% at sea level and 3% at altitude. The second is the discovery that a temperature sensor at the inlet of the compressor sends incorrect readings leading to 2.5% out of 4% steady power shortfall at the compressors correct rotational speed again correctable with a software fix. In addition, Bell Boeing is developing an inlet barrier system to reduce the power loss from the engine ingesting dust and sand particles to supplement the engines existing centrifugal based particle separators as they can only do so much to improve the quality of air they receive.
Cockpit view of a Tu-160 Blended wing profile The Tu-160 is a variable-geometry wing aircraft. The aircraft employs a fly-by-wire control system with a blended wing profile, and full-span slats are used on the leading edges, with double- slotted flaps on the trailing edges and cruciform tail. The Tu-160 has a crew of four (pilot, co-pilot, bombardier, and defensive systems operator) in K-36LM ejection seats. The Tu-160 is powered by four Kuznetsov NK-32 afterburning turbofan engines, the most powerful ever fitted to a combat aircraft. Unlike the American B-1B Lancer, which reduced the original Mach 2+ requirement for the B-1A to achieve a smaller radar cross-section, the Tu-160 retains variable intake ramps, and is capable of reaching Mach 2.05 speed at altitude.
Beetson later told the real reason he pulled out of the game was that he had lost the motivation to keep playing representative football after being overlooked for the test series against France. Beetson was reportedly in line for his first test since the 1977 World Cup, but NSWRL and ARL boss Kevin Humphreys voted against Beetson's selection with a view to the future and the Kangaroo Tour to be held at the end of 1982. Humphreys felt that at 36 Beetson had nothing left to offer the test side. NSW had originally selected South Sydney's Michael Pattison to play , but had fallen ill before the team left Sydney and the flight at altitude had caused a middle-ear infection that forced him to withdraw. Pattison spent the game on the sidelines compiling stats for Channel 7 (Sydney) sideline reporter Barry Ross.
Due to its sound and the possibility that the propeller blades could disintegrate, this situation was particularly frightening for aircrews. More challenging was a loss of power in one engine during takeoff. These and other malfunctions, as well as human error, claimed a number of aircraft and the commanding officer of the 22nd Bombardment Group, Colonel Mark Lewis. The Martin B-26 suffered only two fatal accidents during its first year of flight, from November 1940 to November 1941: a crash shortly after takeoff near Martin's Middle River plant in Maryland (cause unknown, but engine malfunction strongly suggested) and the loss of a 38th Bombardment Group B-26 when its vertical stabilizer and rudder separated from the aircraft at altitude (cause unknown, but the accident report discussed the possibility that a canopy hatch broke off and struck the vertical stabilizer).
Dive tests determined that the Me 262 went out of control in a dive at Mach 0.86, and that higher Mach numbers would cause a nose-down trim that the pilot could not counter. The resulting steepening of the dive would lead to even higher speeds and the airframe would disintegrate from excessive negative g loads. The HG series of Me 262 derivatives was believed capable of reaching transonic Mach numbers in level flight, with the top speed of the HG III being projected as Mach 0.96 at altitude. After the war, the Royal Aircraft Establishment, at that time one of the leading institutions in high-speed research, re-tested the Me 262 to help with British attempts at exceeding Mach 1\. The RAE achieved speeds of up to Mach 0.84 and confirmed the results from the Messerschmitt dive-tests.
The Taigan (), and also known as Kyrgyzdyn Taighany (Kyrgyzskaya Borzaya Taigan in Russian), is a breed of sighthound from Kyrgyzstan. The Taigan is found in the alpine Tian Shan region of Kyrgyzstan on the border with China, it is closely related to the Tazy and the Afghan hound. As a sighthound the Taigan predominantly uses it sight and speed to overcome its prey, it is known for its extraordinary stamina at altitude, but the breed is known for its versatlity whilst hunting, they can follow scent trails and also have a reputation for retrieving game, they are often used to hunt in combination with trained bird of prey, especially the golden eagle. The Taigan is used to hunt a wide range game including marmot, hare, fox, badger, wildcat, hoofed game such as the ibex and roe deer as well as the wolf.
Bell returned a further study, delivered on 4 January 1956, that demonstrated the need to intercept the incoming warheads at altitude, and suggested that this was within the abilities of an upgraded version of the Nike B missile. Given a terminal speed up to 5 miles per second (), combined with the time it would take an interceptor missile to climb to the RV's altitude, the system required that the RV be initially detected at about range. Due to the RV's relatively small size and limited radar signature, this would demand extremely powerful radars. To ensure the destruction of the RV, or at least render the warhead within it unusable, the W31 would have to be fired when it was within a few hundred feet of the RV. Given the angular resolution of existing radars, this limited the maximum effective range significantly.
He had made his first try scoring appearance for a Wales XV in Swakopmund in Namibia in 1990, his second at altitude in Bulawayo, Zimbabwe in 1993 and his last appearance against Ontario in 1997. He won further caps against the US Eagles in San Francisco in the second and decisive game in the United States of America and against Canada in a one-off test near Toronto completing a hat-trick of test wins in North America. It was generally considered that Welsh rugby was in 'disarray' at the time shortly after the arrival of the professional game and he was a late inclusion to both the tour party and the team due to squad injuries. Reference Article "The Independent" - Wales Tour USA and Canada 1997 He had already played in the end of season victory over Romania in Bucharest.
In January 2009, Farah set a new British indoor record in the 3000 metres, breaking John Mayock's record with a time of 7 minutes 40.99 seconds in Glasgow. A few weeks later, he broke his own record by more than six seconds with a time of 7 minutes 34.47 at the UK Indoor Grand Prix in Birmingham, a performance which commentator Steve Cram called "the best performance by a male British distance runner for a generation". Farah attributed his good form to a spell of winter training at altitude in Ethiopia and Kenya. In March 2009 he took gold in the 3000 m at the European Indoor Championships in Turin, recording a time of 7 minutes 40.17. Farah competed at the 2009 World Championships in Athletics: he was in the leading pack early on in the 5000 metres race and eventually finished seventh – the best by a European runner.
The target could be destroyed by the aircraft of a couple squadrons, and could be marked by Rice's Special Duty Flight. Cheshire had worked out his marking technique with 617 Squadron, with Cheshire or Martin marking, while the rest of the squadron waited to hear from him before coming over the target one at a time at altitude. The seeds for disaster were sown with 5 Group's hasty preparation, the lack of a clear understanding of the mission in the minds of the various flight leaders, a lack of familiarity with Cheshire's method, and problems that developed in radio communication that were not apparent until the Main Force Controller was over the target. The wireless operator at his post aboard a Lancaster Throughout the bombing campaign against Germany, Bomber Command aircraft had used HF for Radio Transmission on those occasions when radio silence was broken.
In January 1977, the prototype orbiter Enterprise was delivered to Edwards Air Force Base in California for the beginning of its overall test programme, which would encompass flight tests, fit-check and procedures testing of the orbiter, its systems, the facilities and procedures required to launch, fly and land the spacecraft safely. During 1977, Enterprise was used in what was called the Approach and Landing Tests programme of testing, which encompassed mating the orbiter to the Shuttle Carrier Aircraft, a modified Boeing 747 to test the taxiing and flight characteristics of the Orbiter / SCA combination. This included flights of the combination in which Enterprise itself was powered up and crewed, to test crew procedures systems in flight, and finally a set of five so-called "free- flights", with Enterprise jettisoned from the SCA at altitude to land on its own, testing the orbiter's own flying and handling characteristics.
Almost all of these were captured by the Germans, though they were rarely used. Some were sent to the Slovenské vzdušné zbrane, and 10 remained with RSI's Aeronautica Nazionale Repubblicana, but were not used. Seven were used by the Italian Co-Belligerent Air Force as transports. Shortly after the end of the war, the aircraft was phased out of service. Overall, SM.84 was a failed design (Francesco Pricolo called it a 'wrong aircraft', while Ettore Muti complained in 1941 about its awful handling and take off). It was never liked by its crews and never capable of replacing the SM.79. When the final version of the Sparviero, the SM.79 bis, became available, the SM.84 was withdrawn. In the bomber role it was inferior to the CANT.1007 ter, especially at altitude (the SM.84 was almost impossible to fly above 5,000 m).
The Vixen I and II formed the basis of the Venture army co-operation aircraft for the Royal Air Force and the Valparaiso for export purposes. The next version of the Vixen was the Vickers Type 91 Vixen III, first flying in April 1924 which was fitted with larger wings (with wingspan of 44 ft/13.4 m rather than 34 ft 6 in/10.5 m earlier aircraft) for increased performance at altitude, and reverted to a nose- mounted radiator. The Vixen III was tested with both wheel and float undercarriages, and was later converted back to a landplane, and used for air racing, competing in the 1925, 1926 and 1927 King's Cup Races. The Vixen III formed the basis of the Type 116 Vixen V, fitted with a high-compression Lion V engine and a modified tail, of which 18 were purchased by Chile.
In certain ETO units and possibly elsewhere a prerogative of the fighter ace was a red satin lining which was added on confirmation of his fifth aerial kill. P-51 Mustang pilot wearing a leather A-2 jacket Early wartime pictures show entire bomber crews outfitted with A-2s, although at altitude in a bomber they probably weren't too useful. The pilot and copilot had primitive cabin heat on some aircraft and would wear the A-2, while the rest of the bomber crew usually wore heavier fleece-lined Type B-3 or ANJ-4 (and later B-9 and B-11 parkas) which were warmer and better suited to long hours in the severe cold. However, period photos do show A-2s worn by crew underneath heavy outer garments, and candid on-base photos often show crewmen of all ranks in A-2s.
Early studies indicated that the best option was to base the design on the Air Force requirement, and use a modified version for the Navy. In June 1961, Secretary McNamara ordered the go ahead of Tactical Fighter Experimental (TFX), despite Air Force and Navy efforts to keep their programs separate. The side-by-side seating adopted in the F-111 The Air Force and the Navy could agree only on swing-wing, two-seat, twin-engine design features. The Air Force wanted a tandem-seat aircraft for low-level penetration ground-attack, while the Navy wanted a shorter, high altitude interceptor with side-by-side seating to allow the pilot and radar operator to share the radar display. Also, the Air Force wanted the aircraft designed for 7.33 g with Mach 2.5 speed at altitude and Mach 1.2 speed at low level with an approximate length of .
In: Climate Change and Aviation: Issues, Challenges and Solutions (), Earthscan, London. Key to the concerns expressed in these studies are: that vast distances are easily travelled in a relatively short time, entailing substantial greenhouse gas emissions; that these emissions are made at- altitude where they have much greater climate consequences than emissions made at ground-level; and that social pressuresSee also:"The Bill," by Peter Wedel, distributed by GermanWatch. and marketing programs such as frequent flyer miles programs that both encourage a growing amount of travel and means to go. Climate scientist Kevin Anderson of the Tyndall Centre for Climate Change Research demonstrated in 2009 that continued annual growth in UK air travel at the usual seven percent until 2012 and at three percent thereafter will lead to such travel consuming 70 percent of the UK's total planned national carbon emissions by 2030.Anderson, K. (2008, 17 June).
The tree line is lower closer to the coast and in areas with lower mountains, due to cooler summers, more wind near mountain summits, and more snow in the winter (coastal mountains) leading to later snowmelt. The NB zone covers large areas at altitude in the interior of Østlandet; is in the central mountain areas; but at the western coast the tree line is down to about above sea level, increasing significantly in the long fjords ( at the head of Sognefjord). Further north, large areas in the interior highlands or uplands of Trøndelag and North Norway are dominated by the NB zone, with the tree line at about amsl in the interior of Trøndelag, in Rana, at Narvik, at Tromsø, at Kirkenes and at Hammerfest (only pockets in sheltered areas). The large Finnmarksvidda plateau is at an altitude placing it almost exactly at the tree line.
The surviving R-class Zeppelins were adapted by removing one of the engines.Robinson 1971, p.208 The improved safety was offset by the extra strain on the airship crews caused by altitude sickness and exposure to extreme cold and operating difficulties caused by cold and unpredictable high winds encountered at altitude. The first raid of 1917 did not occur until 16–17 March: the five Zeppelins encountered very strong winds and none reached their targets.Cole and Cheesman 1984, p. 198. This experience was repeated on 23–24 May. Two days later 21 Gotha bombers attempted a daylight raid on London. They were frustrated by heavy cloud but the effort led the Kaiser to announce that airship raids on London were to stop; under pressure he later relented to allow the Zeppelins to attack under "favourable circumstances". On 16–17 June, another raid was attempted.
In January 2008, Rowbury enjoyed her first extended stint at altitude in central Mexico where she trained for six weeks with her coach and teammates. She returned to the United States in February to compete in the USA Indoor Track and Field Championships, her first track race since her injury 11 months earlier. Rowbury went on to win the 3000 m in a personal best time of 8:55.19. In April 2008, Rowbury opened up her outdoor track campaign at the Duke Invitational, winning the 800 m by 12 seconds with a two-second personal best time of 2:02.76. Her next race was in early May at the Payton Jordon Invitational at Stanford University where she hoped to achieve the Olympic A standard at 1500 m (4:07.00). Although Rowbury came up short of her goal while racing at Stanford, she did manage a five-second personal best at this distance with a time of 4:07.59.
Altitude decompression may be a natural consequence of unprotected elevation to altitude, or due to intentional or unintentional release of pressurisation of a pressure suit or pressurised compartment, vehicle or habitat, and may be controlled or uncontrolled. There are three principal physiological effects arising from decompression at altitude: # Decompression illness, which includes decompression sickness due to bubble formation in the tissues similar to those caused by decompression after exposure to pressures higher than sea level atmospheric pressure. There is little evidence of altitude decompression occurring among healthy individuals at altitudes below . # Barotrauma caused by the over-expansion of gas-filled spaces # Altitude sickness, also known as acute mountain sickness (AMS), altitude illness, hypobaropathy, the altitude bends, or soroche, is a pathological effect of high altitude on humans, caused by acute exposure to low partial pressure of oxygen and blood alkalosis arising from the low partial pressure of carbon dioxide at high altitude.
Lewis ended up ranked second behind Soviet Robert Emmiyan, who had the longest legal jump of the year at . At the 1987 World Championships in Athletics in Rome, Lewis skipped the 200 m to focus on his strongest event, the long jump, and made sure to take all his attempts. This was not to answer critics from the 1984 long jump controversy; this was because history's second 29 ft long- jumper was in the field: Robert Emmiyan had leaped at altitude in May, just 4 cm short of Bob Beamon's record.Track and Field News, July 1987, vol. 40 #7, p. 34 But Emmiyan's best was an leap that day, second to Lewis's . Lewis cleared four times. In the 4 × 100 m relay, Lewis anchored the gold-medal team to a time of 37.90 s, the third-fastest of all time. The 100 m final was the most talked about event and caused the most drama.
Artist's concept of an L-2000 in Pan Am livery at altitude in full afterburner (top), and with landing gear extended The new design was designated L-2000-1 and was 223 ft (70 m) long with a narrow-body 132 in (335.2 cm) wide fuselage to meet aerodynamic requirements, allowing for passenger seating of five abreast seating in coach and a four-abreast arrangement in first-class seating. A typical mixed-class seating layout would equal around 170 passengers, with high-density layouts exceeding 200 passengers. The L-2000-1 featured a long, pointed nose that was almost flat on top and curved on the bottom, which allowed for improved supersonic performance, and could be drooped for takeoff and landing to provide adequate visibility. The wing design featured a sharp forward inboard sweep of 80°, with the remaining part of the wing's leading edge swept back 60°, with an overall area of 8,370 ft² (778 m²).
NASA's Paresev glider in flight with tow cable (1962). In 1963, after seeing an image of a Rogallo wing airfoil on a magazine, Dickenson set to build a water skiing kite that could be released at altitude for a glide to a safe drop in the water, thus designed and built a water skiing kite wing he called the Ski Kite. His ski kite format incorporated an airframe with a triangle control frame as used in hang gliding in Breslau 1908, having a basebar tow-point and was integrated on an all-ready publicized four-boom stiffened Rogallo wing airfoil, where the pilot sat on a swinging seat while the control frame and wire bracing distributed the load to the wing as well as giving a frame to brace for weight-shift control. Dickenson's Ski Wing turned out to be stable and controllable, unlike the flat manned kites used at water ski shows.
To prevent disruption to the cellular phone network from the effects of fast-moving cell phones at altitude (see Technical discussion, below), the FCC has banned the use of mobile phones on all aircraft in flight. The FCC did, however, allocate spectrum in the 450 MHz and 800 MHz frequency bands for use by equipment designed and tested as "safe for air-to-ground service" and these systems use far more widely separated ground stations than standard cellular systems. In the 450 MHz band co-channel assignments are at least 497 miles apart and in the 800 MHz band only specific sites were authorized by the FCC. The 450 MHz service is limited to "general aviation" users, usually corporate jets, while the 800 MHz spectrum can be used by airliners as well as for general aviation. The 450 MHz spectrum is named AGRAS while the name of the 800 MHz service is under review following an auction of the spectrum in 2006.

Monino museum The Su-9's fuselage and tail surfaces resembled those of the Su-7, but unlike the swept wing of that aircraft, the "Fishpot" used a 53° delta wing with conventional slab tailplanes. It shared Sukhoi features like the rear-fuselage air brakes as well as the Su-7's Lyulka AL-7 turbojet engine and nose intake. The translating shock cone contains the radar set. The Su-9 was developed from earlier work on a developmental aircraft designated T-3, to which the Su-9 was very nearly identical. Internally at Sukhoi, the Su-9 was known as the T-43. The delta wing of the Su-9 was adopted because of its lower drag in the supersonic flight regime. Its greater volume also allowed a very modest increase in fuel capacity compared to the Su-7. The Su-9 was capable of Mach 1.8 at altitude, or about Mach 1.14 with missiles.
The Junkers company's own 24-cylinder Junkers Jumo 222, liquid cooled six-bank inline engine, with four cylinders in each bank, came the closest to being the only production, single-crankcase design high-output powerplant candidate during the war years, intended to power not only the Junkers Ju 288, but also many other German multi-engined advanced combat aircraft projects. The 222 was a remarkably compact and efficient engine design, being almost identical in cylinder number, displacement and weight to the British Napier Sabre H-type four-bank sleeve valved inline engine, and the best attempt at creating a German aviation engine that could routinely exceed 1,500 kW output at altitude, but as with the BMW designs and even the later Heinkel HeS 011 advanced turbojet engine, never came close to being a production-ready aircraft powerplant, with just under 300 examples of the Jumo 222 produced in total between several different versions.

The Future of Air Transport White Paper (2009), HMSO "The aviation industry is encouraged to take account of, and where appropriate reduce, its contribution to global warming...The impact of aviation on climate change is increased over that of direct CO2 emissions alone by some of the other emissions released and their specific effects at altitude". The Intergovernmental Panel on Climate Change (IPCC) estimates a commercial jet's flight to have some 2-4 times the effect on the climate than if the same CO2 emissions were made at ground level, because of different atmospheric chemistry and radiative forcing effects at the higher altitude.IPCC, Aviation and the Global Atmosphere: A Special Report of the Intergovernmental Panel on Climate Change (2000), Cambridge University Press U.S. airlines alone burned about 16.2 billion gallons of fuel during the twelve months between October 2013 and September 2014.Why airfare keeps rising despite lower oil prices , by Scott Mayerowitz, Assoc.
Figure 1: Single cell cumulonimbus of type turkey tower originating from a castellanus having degenerated All castellanus clouds show that there exists an unstable (or conditionally unstable) layer at their altitude but not necessarily under the cloud. Some scientists (Scorer, Corfidi) define a castellanus as a cloud generated by the release of latent heat during the ascension of a saturated thermal column in an unstable (or conditionally unstable) layer at altitude. The cloud will have the appearance of a turkey tower. This unstable (or conditionally unstable) layer can be generated in different ways: (1) a large scale lifting (synoptic scale) that under some circumstances makes the air unstable since the temperature at the base of the layer decreases more slowly than the temperature at the top of cloud due to adiabatic decompression, (2) a cooling of the cloud top that generates the same differential, and (3) an unstable (or conditionally unstable) airmass advection over a stable airmass, etc.
BSAC nitrox decompression tables The PADI Nitrox tables are laid out in what has become a common format for no-stop recreational tables Dive tables or decompression tables are tabulated data, often in the form of printed cards or booklets, that allow divers to determine a decompression schedule for a given dive profile and breathing gas. With dive tables, it is generally assumed that the dive profile is a square dive, meaning that the diver descends to maximum depth immediately and stays at the same depth until resurfacing (approximating a rectangular outline when drawn in a coordinate system where one axis is depth and the other is duration). Some dive tables also assume physical condition or acceptance of a specific level of risk from the diver. Some recreational tables only provide for no-stop dives at sea level sites, but the more complete tables can take into account staged decompression dives and dives performed at altitude.
87 but learned BMW had preferred the Bosch closed nozzle for the 801, while Junkers chose the open nozzle for the Junkers Jumo 213 inverted V12 aviation engine. They got better information on German aircraft spark plugs, from BMW, Daimler, and Bosch, but not from Beru or Siemens, finding, in general, improvements focused on better performance at altitude or hotter, usually with better insulators or cooling. Investigation of propellers found new research had been halted when RLM decided to focus on jets, only to be resumed. The Mission's interviews were limited to Vereinigte Deutsche Metallwerke (United German Metalworks, VDM), and, at Göttingen, they interviewed Dr. Stüper, who tested VDM's reversible propeller. This three- bladed unit had links to two electric motors, which could change the pitch at two degrees per second for constant speed or 60-100° per second for braking (in reverse mode); it was scheduled for production early in 1945, to be used by the Dornier Do 335, Dornier Do 317, and Focke-Wulf Fw 190.
The role of flight surgeons continued to mature and expand as the U.S. faced World War II. The 1941 movie Dive Bomber, although focused on Naval Aviation, highlighted the role of the flight surgeon just prior to the attack on Pearl Harbor, and demonstrated how solving the problems of hypoxia at altitude would reduce the aircraft mishap rate. During World War II, the head of the U.S. Army Air Forces, General of the Army (later General of the Air Force) Henry 'Hap' Arnold, directed all flight surgeons in the Army Air Forces to fly regularly with their patients in order to better understand the aviation environment. Consequently, to this day, their successor U.S. Air Force Flight Surgeons are considered "aeronautically rated" aircrew members who receive flight pay and who are required to fly a certain number of hours monthly. The same policy applies to Army Flight Surgeons and to Naval Flight Surgeons, the latter who are considered "aeronautically designated" officers like their Naval Aviator and Naval Flight Officer counterparts.
As an improvement to the F11F-1 (F-11A) fighter, Grumman proposed a more advanced version of the airframe known as the F11F-1F Super Tiger. This was the result of a 1955 study to fit the new General Electric J79 engine into the F11F airframe. The Navy was sufficiently interested to authorize modification of two production F11F-1s with enlarged air intakes and YJ79-GE-3 turbojets, with the result being designated the F11F-1F, indicating a production F11F-1 with a special engine fit. The aircraft first flew on 25 May 1956, reaching Mach 1.44 in one of the flights. After the addition of 60° wing root fillets, a 13.5 in (35 cm) fuselage extension, and an uprated J79 engine, the F11F-1F reached an impressive Mach 2.04 in 1957, thus becoming the first naval aircraft in the world to exceed Mach 2 (two years before the F4H, F8U-3, and A3J). This was a surprise even to Grumman, which had expected a top speed of only Mach 1.4 at altitude.
The municipality of Villanueva is located in the southern region of the Department of La Guajira within the valley of the Cesar River, between the Sierra Nevada de Santa Marta mountains and the Serranía del Perijá which Villanueva borders.

Born in Detroit, Michigan, Quincy Watts attended the University of Southern California where he excelled not only as an athlete but also as a wide receiver on the college football team. He took up track at Sutter Middle School and later went to Taft High School in Woodland Hills, California. In 1987, he ran a 10.36s 100 m, which stands as the Los Angeles city section record, and at the time was the second fastest in CIF history, behind only Henry Thomas' 10.25 in 1985. That same year he repeated as the 200 meters Champion at the CIF California State Championships in Sacramento. At first, Watts was a short sprinter, specializing for 100 m and 200 m, but the USC coach Jim Bush, convinced him to run 400 m, where he found his success. In 1992, by far his most successful year, he won the Olympic 400 m title. He twice broke Lee Evans' Olympic record of 43.86, (set at altitude during the 1968 games in Mexico), clocking 43.71 in his semi-final, before going on to record 43.50 in the final. He was a member of the 4 × 400 m relay team, running the second leg in 43.10, which smashed the world record in a time of 2:55.74.
British air power in the theatre also intensified, chief amongst these being the Hawker Hurricane fighter, which forced a redeployment of Italian forces in response. Although considered to be inferior to the Hurricane in terms of speed, the C.200 had the advantage in terms of manoeuvrability, turn radius, and climb rate. According to aviation author Bill Gunston, the C.200 proved effective against the Hurricane, delivering outstanding dogfight performance without any vices.Gunston 1988, p. 255. While the Hurricane was faster at sea level (450 km/h/280 mph vs the C.200's 430 km/h/270 mph), the Saetta could reach more than 500 km/h (310 mph) at 4,500 m (14,800 ft), although speed dropped off at altitude: 490 km/h (300 mph) at 6,000 m (19,700 ft) and 350 km/h (220 mph) at 7,000 m (23,000 ft) with a maximum ceiling of 8,800 m (29,000 ft). Comparative speeds of the Hurricane Mk I was 505 km/h (314 mph) at 5,000 m (16,400 ft) and 528 km/h (328 mph) at 6,000 m (19,700 ft).Lembo 2000, p. 26. Over 5,000 m (16,400 ft) and at very low levels, only the huge Vokes (anti-sand) air filter fitted to the "tropical" variants slowed the Hurricane Mk II to Macchi levels.
Shortly before his death in 1987, he admitted that since 1924 he had never been clear about the exact location along the northeast ridge where he had seen the black dots. A recent theory suggests the two climbers were cresting the First Step after they had given up their climb and were already on the descent. They scrambled up the small hillock to take photographs of the remaining route, much as the French did in 1981, when they too were blocked from further progress. As to which step they were seen on, Conrad Anker has stated that "it's hard to say because Odell was looking at it obliquely ... you're at altitude, the clouds were coming in" but that he believes "they were probably in the vicinity of the First Step when they turned back, because the First Step itself is very challenging and the Second Step is more challenging.... [T]o put them where they might have fallen in the evening and where Mallory's body is resting, because it's a traversing route, he couldn't have fallen off either the First or Second Step and ended up where he was at, they were well to the East of that descending the Yellow Band".
Therefore, a greater volume of air must be inhaled at altitude than at sea level in order to breathe in the same amount of oxygen in a given period. During inhalation, air is warmed and saturated with water vapor as it passes through the nose and pharynx before it enters the alveoli. The saturated vapor pressure of water is dependent only on temperature; at a body core temperature of 37 °C it is 6.3 kPa (47.0 mmHg), regardless of any other influences, including altitude. Consequently, at sea level, the tracheal air (immediately before the inhaled air enters the alveoli) consists of: water vapor ( = 6.3 kPa), nitrogen ( = 74.0 kPa), oxygen ( = 19.7 kPa) and trace amounts of carbon dioxide and other gases, a total of 100 kPa. In dry air, the at sea level is 21.0 kPa, compared to a of 19.7 kPa in the tracheal air (21% of [100 – 6.3] = 19.7 kPa). At the summit of Mount Everest tracheal air has a total pressure of 33.7 kPa, of which 6.3 kPa is water vapor, reducing the in the tracheal air to 5.8 kPa (21% of [33.7 – 6.3] = 5.8 kPa), beyond what is accounted for by a reduction of atmospheric pressure alone (7.1 kPa). The pressure gradient forcing air into the lungs during inhalation is also reduced by altitude.
Redding and Yenne 1997, p. 69. His gamble that customers would be interested in Boeing's unique and expensive new airplane turned out to be correct for a brief period. On November 29, 1945 Pan American World Airways (Pan Am) became the launch customer with the largest commercial aircraft order in history, a $24,500,000 order for 20 Stratocruisers. Earlier in 1945 a Boeing C-97 had flown from Seattle to Washington, D.C. nonstop in six hours and four minutes; with this knowledge, and with Pan Am President Juan Trippe's high regard for Boeing after their success with the Boeing 314 Clipper, Pan Am was confident in ordering the expensive plane. The 377 shared the distinctive design of the C-97, with a "double-bubble" fuselage cross- section, resembling an inverted figure-8, with 6,600 ft³ (187 m³) of interior space shared between two passenger decks. Outside diameter of the upper lobe was 132 inches, compared to 125 inches for the DC-6 and other Douglas types (and 148 inches for today's 737). The lower deck served as a lounge, seating 14. The 377 had innovations such as higher cabin pressure and air conditioning; the superchargers on the four Pratt & Whitney R-4360 engines increased power at altitude and allowed constant cabin pressure.Redding and Yenne 1997, p. 71.
Ettore Bugatti designed several multi-valve aircraft engines. The 1916 Bugatti U-16 1484.3 cid (24.32 L) SOHC 16-cylinder, consisting of two parallel 8-cylinder banks, offered 410 bhp (305 kW) at 2,000 rpm (12.5 kW/liter or 0.28 bhp/cid). Each cylinder had two vertical inlet valves and a single vertical exhaust valve, all driven by rocking levers from the camshaft. Other advanced World War I aircraft engines, such as the 1916 Maybach Mb.IVa that produced at altitude and the 1916 Benz Bz.IV with aluminium pistons and the 1918 Napier Lion (a 450 bhp 24-liter DOHC 12-cylinder), used two intake valves and two exhaust valves. Long after the King-Bugatti "U-16" aviation engine used them, shortly before World War II, the Junkers aviation firm began production of the Third Reich's most-produced military aviation engine (68,000+ produced), the 1936-designed, 35-litre displacement, inverted-V12, liquid-cooled Junkers Jumo 211, which used a three-valve cylinder head designGerman language illistration of Jumo 211 three-valve design inherited from Junkers' first inverted V12 design, the 1932-origin Junkers Jumo 210 — this was carried through into the later, more powerful 1940-origin Junkers Jumo 213, produced through 1945, the production versions of which (the Jumo 213A and -E subtypes) retained the Jumo 211's three-valve cylinder head design.
Bodie 1991, pp. 16–17 Specifications called for at least of heavy armament including a cannon, one or two liquid-cooled Allison V-1710 engines each with a General Electric turbo-supercharger, tricycle landing gear, a level airspeed of at least at altitude, and a climb to within 6 minutesLockheed P-38 Lightning. Retrieved: 21 January 2007.—the toughest set of specifications USAAC had presented to that date.Bodie 1991, p. 14. Brigadier General Benjamin S. Kelsey recalled in 1977 that he and Lieutenant Saville drew up the specification in 1937 using the word "interceptor" as a way to bypass the inflexible Army Air Corps requirement for pursuit aircraft to carry no more than 500 lb (225 kg) of armament including ammunition. Kelsey was looking for a minimum of 1,000 lb (450 kg) of armament. From these specifications a competition was held, and eventually the single-engine fighter became the Bell Aircraft P-39 Airacobra, and the twin-engine fighter became the Lockheed P-38 Lightning. Saville's rank of captain was made permanent in June 1937. SCR-270 set Saville entered the Command and General Staff School at Fort Leavenworth, Kan., in September 1938, and graduated the following June. He then was assigned to Washington, D.C., as assistant to the chief of the Plans Division in the Office of the Chief of Air Corps.
