AirSpeed app was designed to calculate ISA (International Standard Atmosphere) properties, which is useful for aeronautical engineers and pilots. The Off-standard conditions can be determined based on temperature and static pressure of actual flight conditions. Airspeed conversions for ISA atmosphere can be calculated based on Altitude and CAS airspeed. The calculations are performed based on ESDU-77022 - Equations for calculation of ISA and NASA technical publication. The app was designed by KOT Engineering.
