7 Performance
Performance data provided in this section assume an 80% battery drain
and are corrected for ISA conditions at sea level.
Reductions in take-off performance due to environmental conditions or
other factors can be assumed as described in Table 7-1:
Take off distance correction factors
Weight:
-
1% increase in weight: add 2% T/O distance
Density
Altitude:
-
Add 1% T/O distance for every degree Celsius
above ISA conditions (corrected to airfield altitude
with 6.5°C per 1000 m).
Headwind:
-
10 km/h (5 kt) headwind: subtract 7.5% T/O distance
Tailwind:
-
10 km/h (5 kt) tailwind: add 25% T/O distance
-
20 km/h (10 kt) tailwind: add 55% T/O distance
Slope:
-
2% uphill slope: add 15% T/O distance
-
2% downhill slope: subtract 10% T/O distance
Surface:
-
Dry and short grass: add 15% to T/O distance
Table 7-1 Take off distance correction factors
CAUTION
:
Wet and tall grass increases the T/O distance
significantly. Take extreme care when taking off from
soft and/or wet unpaved surfaces.
