Density Altitude Calculator

Density Altitude Calculator

I began this project in my search for an easier way to utilize the performance data in the C172 Pilot Operations Handbook (POH).  While most airports have runways that are long enough for the typical small General Aviation aircraft, a Prudent pilot should be aware of all the conditions pertaining to the flight.  Because most runways are long enough, General Aviation pilots rarely look at the specific performance numbers for take-off and landing requirements.

A typical method of calculating Take off requirements would be…

1.  Look up Field Elevation

2. Look up Temperature

3. Look up Barometric Pressure (altimeter setting)

4.  Calculate Density Altitude

5.  Look up approximate values from the performance data table in the POH.

6.  Interpolate the values from step 5 to the actual(or estimate) Ground Roll necessary.

In stage 1 of the project I have combined steps 1 – 4 in a single click of of the app (start the app and it automatically loads the nearest airport and weather stations).

Stage 2 of the project (In-Process ) will complete steps 5 – 6 automatically and estimate the Ground roll necessary for the given conditions and aircraft.


Available for FREE from the Google Play Marketplace.
