ALPHA Trainer ALPHA Trainer
Best climb speed (Vy) 76 kts
(140 km/h)
Best climb rate at MTOM, sea level 1220 fpm (6.1 m/s)
Climb rate at 100 kts (185 km/h), sea level 800 fpm (4.0 m/s)
Best angle climb speed (Vx) 58 kts (108 km/h)
Effect of outside air temperature
For every 5 degrees Celsius (10 F) of OAT increase versus the ISA, the climb rate decreases by 60 fpm
(0.3 m/s).

NOTE Climb rate is measured at max continuous power (5500 RPM) of the engine with the
flaps retracted at V
y and MTOM.
Climb performance may vary depending on, temperature, altitude, humidity and wing &
propeller surface condition.
Cruise
Aircraft at MTOM, recommended cruise power of 5300 RPM in ISA and sea level altitude, flaps re-
tracted:
ALPHA Trainer ALPHA Trainer
Cruise airspeed 108 kts (200 km/h)
Best economy cruising level or 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 3.6 USgal (13.6 L) per hour. For detailed fuel consumption determination for various
cruising regimes consult the Rotax 912 Operators manual.
Effect of outside temperature
Every 10 degrees Celsius of OAT increase versus the IAS, the cruising speed at 5300 RPM decreases
by 3 kts.
