Landing performance: Using the figures above, the following additional
safety factors should be applied to the distance to clear a 15metre
obstacle on the approach. If unsure, always use these factors to ensure
you have sufficient runway to avoid using the considerately provided
hedge at the far end of the runway.
For every 1000ft you are above sea level
multiply by 1.05
For every 10
0
C above 15
0
C air temperature
multiply by 1.05
For every 2
%
of downslope
multiply by 1.1
If the runway is tarmac or concrete
multiply by 1.2
If the ground is soft, or there is snow or wet grass
multiply by 1.25
If the ground is very soft (or wet) or if the snow is more
than 1” deep
multiply by 1.6
If you have to land with a tailwind
multiply by 1.2 for every 4
knots of wind
Now to be sure, multiply by 1.43, to take into account that you may not fly the
aeroplane as well as the company test pilot did when he worked out the values in the
manual.
