TruAirspeed vs Immerse My City

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).

The Immerse My City App is for any church or believer who is eager and willing to accept the call of the Gospel to bring the love of Jesus Christ everywhere they go. As a ministry, our team at Immerse has organized and led hundreds of community outreaches over the years, finding ways to be more impactful while making the process as straight forward as possible. After fine-tuning our evangelism and outreach processes, we've taken all that we know and created a revolutionary app that will allow you to follow the same effective structures for outreach and follow up.
