An implementation of the International Civil Aviation Organization (ICAO) International Standard Atmosphere (ISA), see ICAO Doc 7488/3.
The library also includes functions for calculating:
- true airspeed (TAS) from calibrated airspeed (CAS), pressure and temperature;
- CAS from TAS, pressure and temperature;
- TAS from Mach number and temperature;
- and the crossover altitude between CAS / Mach flight regimes.
The equations for the functions above are from BADA User Manual revision 3-12.
The library is declared no_std so it can be used in embedded applications.
