This is a Java program that models the properties of the ICAO 1976 Standard Atmosphere. 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, 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.
My 1976 Standard Atmosphere Java program is available in 3 forms. As a downloadable application set up for MacOS X, as an application set up for Windows or as an application set up for use on UNIX based systems. This program and it's source code is covered by the General Public Licence.
