NASA Pathfinder Plus video of helios in flight Atmospheric satellite (United States usage, abbreviated atmosat) or pseudo-satellite (British usage) is a marketing term for an aircraft that operates in the atmosphere at high altitudes for extended periods of time, in order to provide services conventionally provided by an artificial satellite orbiting in space. Atmospheric satellites remain aloft through atmospheric lift, either aerostatic/buoyancy (e.g., balloons) or aerodynamic (e.g., airplanes).

Retrieved: 19 February 2012. Normally a helicopter or gyrocopter cannot fly forward at the same speed as or faster than its rotor tip speed. This is because the low airspeed of the retreating rotor blade would cause retreating blade stall, whilst the advancing rotor blade would be traveling at twice the speed of the aircraft, producing uncontrollable flight due to dissymmetry of lift. However, with the CarterCopter, the fixed wings provide the lift required to remain aloft.

The first Operation Looking Glass mission flown by the squadron took off on 3 February 1961. In March 1963, the squadron was equipped with eight specially-configured KC-135As for SAC's command and control mission. These planes were replaced the following August by KC-135B aircraft with turbofan engines and advanced electronics equipment. These aircraft could remain aloft for longer periods because they added receiver capabilities for air refueling operations, retaining their tanker configuration as well.

There were no spare parts, engines, or propellers for the B-17s in the Philippines; damaged B-17s had to be cannibalized to keep the bombers flying. The only tools were those in the possession of the crews. The men who worked on the planes all night often got no rest the next day because of air alerts. On some days the heavy bombers had to remain aloft during the daylight hours to avoid destruction on the ground.

As tiny water particles that make up the cloud group together to form droplets of rain, they are pulled down to earth by the force of gravity. The droplets would normally evaporate below the condensation level, but strong updrafts buffer the falling droplets, and can keep them aloft much longer than they would otherwise. Violent updrafts can reach speeds of up to . The longer the rain droplets remain aloft, the more time they have to grow into larger droplets that eventually fall as heavy showers.

SHARP, short for Stationary High Altitude Relay Platform, was an experimental aircraft using beam-powered propulsion designed by the Communications Research Centre Canada (CRC) and built by the University of Toronto Institute for Aerospace Studies (UTIAS) during the 1980s. SHARP used microwaves to provide energy from a ground station that powered electric motors spinning propellers to keep the aircraft aloft. The power was also used for the onboard electronics. SHARP could remain aloft indefinitely, and was intended to be used as a sort of low-altitude communications satellite for smaller geographical areas.

The water droplets in a cloud have a normal radius of about 0.002 mm (0.00008 in). The droplets may collide to form larger droplets, which remain aloft as long as the velocity of the rising air within the cloud is equal to or greater than the terminal velocity of the droplets. For non-convective cloud, the altitude at which condensation begins to happen is called the lifted condensation level (LCL), which roughly determines the height of the cloud base. Free convective clouds generally form at the altitude of the convective condensation level (CCL).

At level with stratus nebulosus translucidus (V-89) and opacus (V-90) clouds Stratus fractus (V-88) cloud Abbreviation: St Clouds of the genus stratus form in low horizontal layers having a ragged or uniform base. Ragged stratus often forms in precipitation while more uniform stratus forms in maritime or other moist stable air mass conditions. The latter often produces drizzle. Stratus that touches the Earth's surface is given the common name, fog, rather than a Latin name that applies only to clouds that form and remain aloft in the troposphere.

The small gondola would have navigational and control electronics, along with a stereo imaging system, as well as a spectrometer and magnetometer. Plans envisioned a follow- on to MABTEX as a much more sophisticated aerobot named MGA, for "Mars Geoscience Aerobot". Design concepts for MGA envisioned a superpressure balloon system very much like that of MABTEX, but much larger. MGA would carry a payload ten times larger than that of MABTEX, and would remain aloft for up to three months, circling Mars more than 25 times and covering over .

A copper tubing system was installed in an attempt to adequately lubricate the rocker arms of the engines inflight. Doorways were cut on each side of the cockpit and catwalks built on the wings to enable mechanic Roy Hooe to access the engines for emergency maintenance. To reduce propeller noise, the two wing engines were mounted with Westinghouse twin- blade Micarta propellers, while the nose engine used a Standard three-blade steel propeller. As word of the project spread, its members were continually being asked how long they expected to remain aloft.

During the 1962 July–August storm season in Flagstaff, Arizona, the scientists, selected "guinea pig" storms, and seeded them with chemicals. Effects were thoroughly analyzed from the ground and from the air with time-lapse motion picture cameras, stereo still cameras, storm radar, lightning detectors, and airborne heat sensors. Among the agents inserted in selected clouds were "condensation nuclei" which temporarily increased the number of water droplets in the cloud, and pulverized dry ice, which turns a portion of the cloud to fine snow crystals that remain aloft. The utilization of these agents facilitated study of a storm's characteristics.

One group of supplementary features are not actual cloud formations, but precipitation that falls when water droplets or ice crystals that make up visible clouds have grown too heavy to remain aloft. Virga is a feature seen with clouds producing precipitation that evaporates before reaching the ground, these being of the genera cirrocumulus, altocumulus, altostratus, nimbostratus, stratocumulus, cumulus, and cumulonimbus. When the precipitation reaches the ground without completely evaporating, it is designated as the feature praecipitatio. This normally occurs with altostratus opacus, which can produce widespread but usually light precipitation, and with thicker clouds that show significant vertical development.

With just over nine minutes left in the third period, Predators head coach Barry Trotz was told that the game may have to be stopped. Although the game continued to completion, at the game's end fans were not allowed to leave the arena until the storm had passed. National Weather Service Meteorologist Bobby Boyd theorized that cold air downbursts impinged on the development of a strong, low-level circulation as the storm moved through the Nashville area, forcing the area of rotation to remain aloft as it crossed over Davidson County and downtown Nashville. Radar loop of the Nashville, Jackson and Christian County, Kentucky supercells.

While gliders are being launched, the other gliders which are already airborne will attempt to remain aloft and stay in the vicinity. Gliders that land due to loss of lift are allowed to relaunch ("re-light") but must wait until all other gliders have been launched at least once. Once all gliders in a class are launched and have had time to get into a position to start, the launch director will announce that the "start gate is open" via radio. This means that pilots can begin flying their assigned task and can start immediately, or might delay their start for tactical or weather-related reasons.

The MQ-4C can remain aloft more than 30 hours at at speeds of up to . Its surveillance sensor is the AN/ZPY-3 Multi-Function Active Sensor (MFAS) X-band AESA radar with a 360-degree field-of-regard, capable of surveying of sea (as well as shoreline or land) in a 24-hour period, or in a single sweep. Using the radar in inverse synthetic aperture mode, the MFAS can identify a target in all weather conditions. It can take high definition radar pictures, then use the advanced image and radar return recognition software of the onboard Automatic Identification System (AIS) to classify it without the intervention of aircraft operators.

Julie's original power (and that most associated with the character) was unaided flight by means of rapid forward propulsion that left a highly visible tri-colored band of light in her wake. Julie could only remain aloft while in motion, however, as she discovered when she first used her powers, only managing to stop when she accidentally collided with the bulkhead of a Snark starship and broke her arm.Power Pack #2 Julie never flew at the speed of light as her codename suggested and her top speed remains unknown, but it was supposed by her brother Alex on one occasion that she had broken the sound barrier.Power Pack #13 Julie gained the density powers previously held by her brother Jack for a time and operated under the name Molecula.

This NB chapter was remarkable in other ways. He leveraged his support for the military into outstanding stories from the army at CFB Gagetown and flights with the air force to the Canadian Arctic, the Caribbean and the Mediterranean; usually rough no-frills passage, brief stops (if any) - the RCAF CP-107 Argus could remain aloft over the Arctic for up to 30 hours per flight - and down time almost exclusively in military messes, but great adventures for a young reporter. It was during this Fredericton period that Bannerman became schooled in political strategy, developing friendships with a notable Liberal backroom strategist Wendell Fulton and Conservative thinkers such as the national guru Dalton K. Camp and Richard B. Hatfield. Hatfield, who became a close personal friend for the rest of his life, became the longest serving Premier in NB history (1970–1987).

The first E-4A was completed at the Boeing plant outside Seattle, Washington in 1973. E-Systems won the contract to install interim equipment in these three aircraft, and the first completed E-4A was delivered in July 1973 to Andrews Air Force Base, Maryland. The next two were delivered in October 1973 and October 1974. The third E-4 differed by being powered by the GE F103 engine, which was later made standard and retrofitted to the previous two aircraft. The A-model effectively housed the same equipment as the EC-135, but offered more space and an ability to remain aloft longer than an EC-135.Michell 1994, p. 265. In November 1973, it was reported that the program cost was estimated to total $548 million for seven 747s, six as operational command posts and one for research and development. In December 1973, a fourth aircraft was ordered; it was fitted with more advanced equipment, resulting in the designation E-4B.
