Climb performance
ALPHA Trainer
best climb speed
best climb rate at MTOM, sea level
climb rate at 100 kts (185 km/h), sea level
ALPHA Trainer
76 kts (140 km/h)
1220 fpm (6.1 m/s)
800 fpm (4.0 m/s)
Effect of outside temperature
Every 5 degrees Celsius (10 F) of OAT increase versus the ISA, the climb rate decreases by 60 fpm (0.3
m/s).
Effect of altitude

0 m (0 ft) 1220 fpm (6.1 m/s)
500 m (1600 ft) 1180 fpm (5.9 m/s)
1000 m (3300 ft) 1100 fpm (5.5 m/s)
1500 m (5000 ft) 1020 fpm (5.1 m/s)
Note: climb rate is measured at max continous power (5500 RPM) of the engine with flap
retracted at Vy and MTOM.
Climb performance may vary depending on, temperature, altitude, humidity and wing &
propeller surface condition.
