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).
What’s New
Version 2.0
TruAirspeed can now be used in landscape mode on all iPhone models (except the 1st generation iPhone SE).
I've updated the app for operation under iOS17 and iPadOS17, and for compatibility with all current iPhone and iPad models.
I've fixed a bug with the ASI correction factor.
I've also done a significant amount of code cleanup.
Otherwise, features and functionality are unchanged.
