Robin HR100/210 G-BAPY
performance data

This page contains take-off and cruise performance data for G-BAPY, a Robin HR100/210. It also has a handy take-off distance calculator.

Take-off distance calculator

The calculator performs take-off distance calculations using the data from the tables below, by interpolating between the data points. The answers it gives are the Take-off Run and the Take-off Distance Required (TODR) - i.e. the distance needed to reach a height of 50 feet.

 This is currently under test. Use it with caution!

Important safety note: I use this calculator for doing take-off performance calculations before flying G-BAPY, 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 (not even other HR100s). You must use the data taken from the POH of your particular aircraft. I do not guarantee the accuracy or correctness of this calculator; it is your responsibility to ensure that your performance calculations are correct.

Take-off performance data

The following table gives unfactored take-off distances (in metres), with 12 degrees of flap on a hard runway with nil wind. The figures include an extra 5% allowance required by a CAA change sheet inserted into the POH.

The table below gives the scaling factors that reduce the take-off distances at various headwind components. The positive headwind factors are taken from G-BAPY's handbook; the negative tailwind factors have been calculated from the data in the CAA's safety leaflet on aircraft performance.
