CRUISE PERFORMANCE

Conditions
Reference cruise parameters:
RPM KIAS
5300 100
NOTE: Best economy cruising level for the ALPHA Trainer is 6000 ft. There,
cruise performance is equivalent or better than above due to IAS-TAS
relation, but fuel consumption is lower. At these parameters the fuel burn
is around 13.6 litres per hour. For detailed fuel consumption determination
for various cruising regimes consult the Rotax 912 Operators manual.
5.8.2.

EFFECTS OF OUTSIDE AIR TEMPERATURE

For every 10°C of OAT increase versus ISA, the cruising speed at 5300 RPM
decreases by 3 kts.

DESCENT

Reference values:
Sink rate - 58 KIAS - flaps (0)
Best L/D ratio speed - flaps (0)
Best L/D ratio - flaps (0)
