CLIMB
 Standard climbs:
o 2050 rpm
o 30 kp/cm² manifold pressure
o 120 km/h
o Cylinder head temperature not over 240 °C
o Oil temperature not over 85 °C
85 °C is allowed for not more than 15 minutes, then reduce to 50-60 °C
o Oil pressure 4 - 6 kp/cm²
o Fuel pressure 0.2 - 0.5 kp/cm²
 Monitor engine instruments carefully
 When temperatures are too high open engine and/or oil radiators
 Expect to reach service ceiling (3960 meters) after 48 minutes
 Expect vertical speeds between 4,6 m/s at sea level and start power down to 3.8 m/s above 2000
meters
For an increase in power: increase rpm then increase manifold pressure
For a decrease in power: lower manifold pressure then lower rpm
CRUISE FLIGHT
 As soon as cruise altitude is reached the aircraft will be configured to cruise setting
 Fast cruise:
o 1860 RPM
o 665 - 695 MP
o 160 - 165 km/h
 Slow cruise:
o 1730 RPM
o 615 - 645 MP
o 145 - 150 km/h
 Airspeeds:
o Minimal = 108 km/h
o Maximum = 220 km/h
o Maximum in turbulent air : 140 km/h
 Optimal engine variables:
o Cylinder head temperature : 140 - 210 °C
o Oil temperature : 50 - 75 °C
o Oil pressure = 4 - 6 kp/cm²
o Fuel pressure = 0,2 - 0,5 kp/cm²
 Every 15 minutes set rpm to 1500 (using propeller controls)
DESCENT
 Maintain 3 - 4 m/s sink rate (with passengers do not exceed 3 m/s)
 Optimal airspeed between 130 and 150 km/h
 Check engine variables
