TruAirspeed vs Handy Pilot

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).

"Handy Pilot" is designed to be used not only by trainees but also by professional pilots. It will become the best partner that can perform complex calculations on your behalf. With this app, your daily flight will definitely become smarter. Enjoy Handy Pilot and have a safe flight. Tools : "Unit Converter" - converts units used in everyday flight operations. "Time Calculator" - add, subtract, multiply, and divide time values. "Turning Radius" - calculates the turning radius based on speed and bank angle. "STD Rate Turn" - calculates the bank angle for making a standard rate turn. "Wind Component" - calculates the crosswind and headwind components. "Wind Limitation" - calculates the wind speed that can meet your limitation, in each wind direction. "Descent Rate" - calculates the descent rate required to maintain the desired path. "ILS Height Check" - calculates the passing altitude at the desired point based on the temperature at that time. "Path Calculator" - calculates the actual path angle based on the true altitude. "Descent Point" - calculates the starting point of descent to obtain the desired descent angle based on the true altitude. "PAPI" - calculates the altitude at which each PAPI indication can be obtained at the desired point. "ILS vs PAPI" - calculates the change in the PAPI indication during the ILS approach. "Entry Pattern" - calculates holding entry pattern based on heading. "Load Factor" - calculates the load factor based on the bank angle. It can also calculate the bank angle at which any load factor can be obtained. * Available on iOS 14.1 and later. * Purchase is required to use all the features.
