Free Version
Publisher Description
TruAirspeed is a True Airspeed Calculator for the iPhone and iPad. It's a bit different from other true airspeed calculators, in which the pressure altitude is an input. This requires resetting the altimeter to the standard sea level pressure of 29.92"Hg to read the pressure altitude. With TruAirspeed, you input the indicated altitude and the Kollsman window's pressure setting — the app then calculates the pressure altitude, density altitude, true airspeed and mach number for you.
The calculations involved take full account of compressibility effects, but not shock waves, so it's limited to subsonic, non-transonic flight only.
You have a choice of units for inputs and results, and you may choose either a calculator-style keypad (top row: 7-8-9) or a telephone-style keypad (top row: 1-2-3). You may also set a correction factor for your bird's airspeed indicator/pitot-static system, if you know it (mine is 0.95).

In Version 1.4, TruAirspeed has been updated for operation under iOS15 and iPadOS15, and for compatibility with all current iPhone and iPad models. I have also added my Privacy Policy to the Info screen. Otherwise, appearance, features and functionality are unchanged.
