Standard temperature and pressure sea level
WebbThe International Standard Atmosphere defines what consitutes a "normal" atmosphere. The sea level pressure is defined as 1.01325 bar (29.92 inches of mercury); the sea level temperature is defined as 15° C (59° F); and the temperature decreases at a lapse rate. True altitude corresponds to the normal sense of what we think of as elevation ... WebbIt is called ” standard pressure ” because 29.92 In-Hg (or 1013.25 hPa) is the standard atmospheric pressure at sea level according to both the ISA (International Standard Atmosphere ) and the US 1976 Standard Atmosphere. Suppose the minimum safe altitude along your route is 19,000 ft MSL and current pressure is 29.42.
