Eect of elevation
The table below provides data about the eect of elevation on takeo runway length.
elevation (m) 0 500 1000 1500
atmosph. pressure (hPa) 1012 954 898 845
outside temperature (°C) 15,0 11,7 8,5 5,2
Takeo runway length [m (ft)]
Model 912 95 (310) 119 (390) 146 (475) 170 (565)
WARNING: If the outside temperature is higher than the standard value it is mandatory to
consider the takeo runway length prolongs as follows: L = 1,10 • (L
h
+ L
t
- L
0
).
Abbreviations are as follows:
L
h
= takeoff runway length at present elevation,
L
t
= takeoff runway length at sea level at same atmospheric conditions,
L
0
= takeoff runway length at 15°C.
The graph below indicates how takeo runway length changes as altitude increases.

Eect of the wind
Wind (head, cross or downwind - also called tailwind) aects aircraft’s ground speed (GS).
Headwind on takeo and landing causes the Takeo and Landing runway length to shorten as the
GS is smaller during these two ight stages. The opposite stands for tailwind on takeo and landing
as tailwind prolongs Takeo and Landing runway length signicantly.
The data on the next page was obtained through testing and therefore serve as informative values
only.
