Standard atmosphere. At sea level, the standard atmosphere consists of a barometric pressure of 29.92 inches of mercury ("Hg) or 1013.2 millibars, and a temperature of 15 C (59 F). Pressure and temperature normally decrease as altitude increases.

If you don't like the weather in Ithaca, just wait a few minutes. It'll get worse.

The air throughout the column is compressed by the weight of the atmosphere above it and thus the density of a column of air is greatest at the surface and decreases exponentially with altitude as shown in the following graph which is a plot of the ...
Atmosphere. The mass of air which surrounds the earth and rotates with it. International Standard Atmosphere is an imaginary condition of the atmosphere to which the performance of all aeroplane is referred for exact comparison.
atmosphere - The gaseous or air portion of the physical environment that encircles a planet. In the case of the Earth, it is held more or less near the surface by the earth's gravitational attraction.
The atmosphere is the ocean upon which all airplanes fly. And the atmosphere is a very dynamic, rapidly changing, and sometimes forceful place. There are times when pilots misjudge the weather they face.
STANDARD ATMOSPHERE
the atmosphere defined in U.S. Standard Atmosphere, 1962 (Geopotential altitude tables)
STANDARD RATE TURN
A turn of three degrees compass heading per second.
Standard Atmosphere Model The atmosphere is a thin layer of gas that separates the surface of the planet from outer space. The properties of the gas change with altitude through the atmosphere.
A standard atmosphere has been established to enable comparison of aircraft performance, calibration of instruments (altimeters, transponders encoders, etc) and meteorological purposes.
The Earth's atmosphere is classified into various layers. The lowest layer, the troposphere, extends from the surface to an average altitude of 7 miles. The second layer is the stratosphere which is 26 to 29 miles thick.

Aero - That portion of the atmosphere that lies over Great Britain. Aerodrome - British word for airport.
CAS is equal to true air speed in standard atmosphere at sea level. See also TRUE AIR SPEED and INDICATED AIR SPEED.
As the signal passes through the atmosphere, it can be slowed down a little — something known as propagation delay. Modeling the likely conditions at a given moment in time is one way to predict and compensate for these errors.
This tank holds an amount of hydraulic oil and is vented to the atmosphere. Unfortunately in a weight sensitive Hovercraft this tank is dead weight and not appealing et all. Also it is a fact that custom made tanks are not cheap.
Altimeter - Instrument that by measuring the pressure of the atmosphere displays altitude information
Altimeter Setting - Barometric pressure reading used to adjust the altimeter ...
Critical Altitude: The maximum altitude at which, in standard atmosphere, it is possible to maintain, at a specified rotational speed, a specified power or a specified manifold pressure.
Contrails tend to form very high up in the atmosphere, and can cause the development of cirrus clouds. In some cases they can linger for hours. They linger longer when humidity levels are high.
The exosphere is the uppermost layer of the atmosphere. It begins at about 700 km or 435 miles up and fades off into the vacuum of space. The gases up there are extremely thin and there is not much oxygen, mostly hydrogen.
An amine blush is a surface effect resulting from the curing agent reacting with Carbon Dioxide (CO2) in the atmosphere rather than the epoxy resin.
International Standard Atmosphere An imaginary atmosphere that assumes at mean sea level a temperature of 15° C and a pressure of 1,013Â-2 millibars, and a fall in temperature of 6Â-5°C per 1,000m of increased height from sea level up to 11,000m, ...
ISA - International Standard Atmosphere - a set of standard conditions or temperature and pressure which serve as a basis for comparison. ISA = pressure 1013.2 millibars, temperature 15 degrees C.
It was the first pressurized aircraft, meaning that air was pumped into the aircraft as it gained altitude to maintain an atmosphere inside the cabin similar to the atmosphere that occurs naturally at lower altitudes.
STANDARD AIR (Standard Atmosphere) - An arbitrary atmosphere established for calibration of aircraft instruments. Standard Air Density is 29.92 inches of mercury and temperature of 59° F, equivalent to an atmospheric air pressure of 14.
The branch of meteorology that deals with atmospheric effects on the operation of vehicles in the atmosphere, including winged aircraft, lighter-than-air devices such as dirigibles, rockets, missiles, and projectiles.
This reservoir was 4 3/4 in. in diameter and 33 1/2 in. long, was tested to a pressure of 20 atmospheres, and worked generally at 7 atmospheres; its weight was only 1.54 lbs., and its cubical capacity 0.28 cub. ft.
The study of the science and technology of travel in the space above the earth. Aerospace includes travel within the atmosphere as well as in space beyond the earth's atmosphere.

The new model offers a 6,000-foot cabin at 25,000 feet and 8,500-foot atmosphere at the airplane's 28,000-foot maximum approved altitude.
An open-circuit wind tunnel in which gas stored under pressure is allowed to expand through a test section to provide a stream of gas or air to test a model. The gas then escapes into the atmosphere or into an evacuated chamber.
