Standard atmosphere conditions
Webb18 apr. 2024 · In addition to the standard atmosphere, it is important to be able to calculate the performance of aeronautical vehicles under non-standard conditions. In particular, it … In aeronautics and fluid dynamics the "International Standard Atmosphere" (ISA) is a specification of pressure, temperature, density, and speed of sound at each altitude. The International Standard Atmosphere is representative of atmospheric conditions at mid latitudes. In the USA this information is specified the U.S. Standard Atmosphere which is identical to the "International Standard Atmosphere" at all altitudes up to 65,000 feet above sea level.
