Takeoff performance data. The calcualtor is copied from the following website:     Thomas Arsenault Takeoff Performance Calculator.     The numbers shown here are changed for the Vans RV-6A aircraft.

The following table gives takeoff distances (in feet) for RV-6A aircraft, showing the effects of aircraft weight, head-wind, altitude and ambient temperature, with flaps up on a hard runway. The figures include an extra 10% allowance required by a FAA change sheet inserted into the POH.

Takeoff distance calculator

The calculator below performs takeoff distance calculations using the data from the table above. It works by calculating the density altitude (using the pressure, temperature, dew-point and airfield elevation), then interpolating between the data points in the table. The answer it gives is the Takeoff Distance Required (TODR) - i.e. the distance needed to reach a height of 50 feet.

Important safety note:This calculator is for use doing takeoff performance calculations before flying RV-6A aircraft, but you should be aware that this calculator is specific to that particular aircraft. The answers it gives are not applicable to any other aircraft. You must use the data taken from the POH of your particular aircraft.
