This application converts the various aerodynamic speeds from one to the other (calibrated, equivalent, true and Mach number) and calculates the International Standard Atmosphere (ISA) properties as a function of pressure altitude and deviation temperature in degree Centigrade. This is a very simple utilitarian engineering application I developed for myself that I'm making available, no eye candy here.
