1976 Standard Atmosphere Program

Std. Atmosphere Application Icon  

This is a Java program that models the properties of the ICAO 1976 Standard Atmosphere to an altitude of 1000 km. This program models the variation of temperature, pressure, density and speed of sound with altitude in a "standard" atmosphere. In addition, this program calculates various airspeeds, Mach number, and dynamic viscosity as well. Simply enter any parameter(s) that you know, in a variety of units, and the others will be calculated automatically. For instance, if you know the altitude and Mach number, enter them, and the airspeeds (equivalent, calibrated, and true) will be calculated automatically. Or, if you know the calibrated airspeed and the Mach number, you can enter them and the altitude (and a lot of other parameters) will be automatically calculated.
