9. Take-Off Performance
The following factors are to be applied to the computed take-off distance for the
noted condition:
Wind:
The following wind corrections are calculated considering the 50% of headwind
component and 150% of tailwind component.
- Headwind: subtract 5% and 4% respectively from the ground and
total distances for each 3 knots headwind.
- Tailwind: add 19% and 15% respectively to the ground and total
distances for each 3 knots tailwind.
Grass runways:
Add 20% to the ground roll distance.
Runway slope:
Increase ground roll distance for each 1% upslope, applying the following
factors:
- 11% at Sea level
- 14% at 5000 ft
- 20% at 10000 ft
Decrease ground roll distance for each 1% downslope, applying the following
factors:
- 9% at Sea level
- 11% at 5000 ft
- 15% at 10000 ft
Weight Correction:
Consider about 17% of take-off distance reduction for each 50 kg (100 lb) of
weight reduction.
