5.8.1. CRUISE PERFORMANCE
Conditions Weight: MTOM ( 1212 lbs / 550 kg)
Temperature: ISA
Wind: zero
Altitude: sea level
Flaps: (0)
Reference cruise parameters:
RPM KIAS FF [US gal] / [liter/h] ENDURANCE
5300 100 3.6 / 13.6 3 hrs + 30 min reserve
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.
5.9. DESCENT
Reference values:
Sink rate - 58 KIAS - flaps (0) 460 ft/min
Best L/D ratio speed - flaps (0) 64 KIAS
Best L/D ratio - flaps (0) 15:1
