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 503 123 (405) 155 (505) 191 (625) 224 (735)
Model 582 100 (330) 139 (455) 170 (555) 195 (640)
Model 912 93 (305) 117 (380) 143 (465) 165 (540)
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°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.
