This application calculates temperature and true airspeed based on altitude and Mach number. The program utilizes the NASA standard atmosphere of 1976 and is accurate to 282, 144 feet (~86km).

The application displays static or ambient temperature in Rankine, Fahrenheit, Kelvin, and Celsius and total temperature in F and C.

In addition, true airspeed in the following units is displayed:

* knots

* ft/sec

* meters/sec

* nm/min

* statute miles per hour

* kilometers per hour

Performs the calculation when you hit return and stores your last calculation performed when you exit the program.

Meant for use by Aero Engineers for quick computations or anybody just wondering how fast supersonic really is. I'm fairly confident that the program is accurate; however, I want to make the program better and as accurate as feasible so your input is most welcome.
