atmospalt
Calculate pressure altitude based on ambient pressure
Description
computes the pressure altitude based on ambient pressure. Pressure altitude is the altitude
with specified ambient pressure in the 1976 Committee on Extension to the Standard
Atmosphere (COESA) United States standard. Pressure altitude is the same as the mean sea
level (MSL) altitude. pressureAltitude
=
atmospalt(pressure
,action
)
This function extrapolates altitude values logarithmically below the pressure of 0.3961 Pa (approximately 0.00006 psi) and above the pressure of 101,325 Pa (approximately 14.7 psi).
This function assumes that air is dry and an ideal gas.
