|. International Standard Atmosphere (ISA) is a model used for the standardization of aircraft instruments. It was established, with tables of values over a range of altitudes, to provide a common reference for temperature and pressure. Flying in ISA-plus temperatures will have a negative impact on aircraft performance.
The standard atmosphere (symbol: atm) is a unit of pressure equal to 101325 Pa or 1013.25 hectopascals or millibars. Equivalent to 760 mmHg (torr), 29.92 inHg, 14.696 psi. (The pascal is a newton per square meter or in terms of SI base units, kilogram per meter per second-squared.).he standard atmosphere (symbol: atm) is a unit of pressure equal to 101325 Pa or 1013.25 hectopascals or millibars.
