Take-off performance
All data published in this section was obtained under following conditions:
Aircraft at MTOM
Elevation: sea level
Wind: calm
Runway: hard runway
Data extrapolated for ICAO standard atmosphere
ALPHA Trainer
ALPHA Trainer
Takeoff ground roll at MTOM
555 ft
Takeoff runway length (over 50 ft/15 m obstacle)
870 ft
NOTE
In order to meet the data for takeoff runway length over 50 ft obstacle maintain V
x
(58
kts, 108 km/h) after take-off.
Soft (grass) runways increase the published take-off performance data by 20%.
Takeoff runway length may vary depending on the wind, temperature, elevation and wing &
propeller surface condition.

The table below provides data about the effect of elevation on takeoff runway length.

WARNING:
Calculating take-off performance in Hot Atmosphere, it is mandatory to con-
sider the takeoff 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, ISA standard conditions
L
t
= takeoff runway length at sea level at same temperature/wind as on the given location,
L
0
= zero wind takeoff runway length at 15°C at sea level.
e.g. if outside temperature is 25°C and you are on 500 m elevation, your takeoff runway length
will be:
L = 1,10 • (L
h
+ L
t
- L
0
) = 1,10 • (205 m + 215 m
- 180 m) = 264 meters.
