Takeoff and Landing Distances

Instructions Each time this page is refreshed a new set of "Conditions" will be generated.

Attempt to calculate the takeoff/landing distances using either of the techniques listed below.

For these solutions, the aircraft weight is assumed to be more than 2200lbs but not greater than 2400lbs. Use the appropriate chart from your POH when performing these calculations for an actual flight.

For the purposes of these problems any winds that are VRB (variable) will be assumed to be a tailwind.

Conservative, Quick Calculation
Determine pressure altitude and temperature. In the charts, use the next highest pressure altitude and next highest temperature that falls within the charts

Calculation Using Interpolation
This is the method you are expected to be able to demonstrate for the purposes of an exam.
Determine pressure altitude and temperature. In the charts, interpolate for the actual temperature and actual pressure altitude. Refer to this Performance Worksheet for assistance.

Regardless of the technique used, ensure you account for headwind/tailwind and runway surface.

Once you have the take-off and landing distances, ensure the runway is long enough for your purpose. The column heading in the solution will turn red if the runway is too short.

NOTES:

Short field technique as specified in Section 4.
Prior to takeoff from fields above 3000 feet elevation, the mixture should
be leaned to give maximum RPM in a full throttle, static runup.
Decrease distances 10% for each 9 knots headwind. For operation with
tail winds up to 10 knots, increase distances by 10% for each 2 knots.
For operation on dry, grass runway, increase distances by 15% of the
"ground roll" figure.

NOTES:

Short field technique as specified in Section 4.
Decrease distances 10% for each 9 knots headwind. For operation
with tail winds up to 10 knots, increase distances by 10% for each 2

For operation on dry, grass runway, increase distances by 45% of
the "ground roll" figure.
If landing with flaps up, increase the approach speed by 9 KIAS and
allow for 35% longer distances.
