4.5.6. Normal Take-off
- Throttle lever – full open,
- control stick set into neutral position
- direction on the ground run controled by rudder pedals
- unstick at speed at 80-85 km/h ( according to take off weight )
- accelerating at speed 110-120 km/h ( acceleration after unstick )
- adjust cruising power (engine speed to 5500 r.p.m. max. continuous power (MCP))
- at heigth 50m AGL wing flaps up
4.5.7. Climbing
Normal climbs are conducted at climb speeds 110 - 120 km/h in accordance with the
take off weight of the aeroplane. Monitor oil temperature, head temperature and oil
pressure during climb. Oil temperature limits must not be exceeded. In case of high
readings, increase airspeed and reduce engine power setting.
4.5.8. Cruise
The range of cruising speeds is from 140 to 250 km/h in accordance with the engine
speed setting from 4000 to 5200 r.p.m. The economy airspeed for best fuel economy
is at 140 km/h, the optimum operation is between 180 km/h to 200 km/h. In case of
turbulence reduce cruising speed below 160 km/h. Under certain conditions the
aeroplane may be overstressed. The aeroplane is able to be trimmed through the
range of the cruising speeds. Due to economy reasons is recommended to maintain
the following data:
