Normal procedures
Initial climb
When airborne, engage brakes momentarily to prevent in-ight wheel spinning.
Accelerate at full power and later maintain proper speed of climb.
As you reach 90 km/h (50 kts) at above 50 meters (165 ft), set aps to 1
st
stage, reaching 110 km/h
(60 kts) at above 100 meters (330 ft) set aps to neutral position. Reduce RPM by 10% and continue
climbing at 115 km/h (62 kts).
Adjust the trim to neutralise the stick force if necessary.
Remember to keep the temperatures and RPM within operational limits during this manoeuvre.
CAUTION! Reduce RPM and increase speed in order to cool the engine down if necessary.
Reaching cruise altitude, establish horizontal ight and set engine power to cruise.
Cruise
As horizontal ight has been established, verify on-board fuel quantity again.
Keep the aircraft balanced while maintaining desired ight parameters.
Should you desire to cruise at low speed (up to 130 km/h (70 kts)), set aps to neutral position other-
wise aps should be set to negative position (ap handle full down).
Check engine operation and ight parameters regularly!
WARNING! Virus 912 is sensitive to correct ap settings. To maintain excellent and safe ight
performance it is important to set aps according to airspeed. As the pilot you must know that
the higher the speed the greater the force on the apperons. To prevent overstressing the ap-
perons it is of vital importance to always y at the correct ap setting as you may otherwise dam-
age the apperons controls’ inner structure.
At speeds in excess of VNE, even at negative ap setting this may lead to utter, loss of control
over aircraft, serious injury and even loss of life.
CAUTION! Do not, under any circumstances attempt to y the aircraft at speeds exceeding
150 km/h (80 kts) using ap setting other than negative!
Flying the 912 Model, check fuel levels as well. For it fuel system design, the fuel tents to gradually
cross-ow from the right tank to the left. To prevent this, shut the right fuel valve by 1/2 and open it
again when the fuel level inside left tank has lowered.
Cruising in rough atmosphere
Should you experience wake turbulence, reduce airspeed and continue ying with aps set to neu-
tral position.
CAUTION! In rough air, reduce engine power if necessary to keep airspeed below VRA.
