extension or starting should fail.
NOTE:
When extending or retracting the engine, the ignition switches must be in OFF
position. The controlling electronics do not allow the extending or retracting if these switches
are ON.
NOTE:
The controlling unit does not allow running the starter, if the engine is in any other
position than extended.
WARNING
: if engine starting is unsuccessful and the ground height has decreased below
150 m (450 ft) AGL, land on the selected emergency strip.
Take into consideration that the extended engine with stopped propeller creates a significant
drag and its mass is high over the centerline of the aircraft. This decreases the flight
characteristics of the aircraft, its glide ratio and stall speed, particularly in a turn. That is why
when flying in this configuration keep higher speed and do not exceed a bank angle of 30
degrees in turns.
4.9 APPROACH AND LANDING
1. Before turning to the base leg check the dive brakes.
2. Set speed to 90-100 km/h [49-54 kt]. In case of turbulence or rain increase it to 100-110
km/h [54-60 kt]. Maintain these speeds during the whole approach.
3. On final, use the dive brakes to control the descent of the aircraft (fully extended, the
glide ratio drops to less than 1:7). Operate the dive brakes gently to prevent dropping or
floating of the aircraft.
3. At the height of 5 m (15 ft), smoothly raise the nose to horizontal flight to flare at 0.3-0.5m
[1 – 1.5 ft] above the ground. In order to prevent a rough contact with the ground, reduce
the dive brakes. Allow the speed to reduce by holding the constant height such that the
aircraft lands at the speed of 60-65 km/h [32-35 kt] on the wheel. Maintain this "wheel"
position until the front wheel settles to the runway by itself.
4. The landing can be shortened by full extension of the dive brakes and by using the wheel
brake immediately after the landing.
5. Also the switching off the engine in the approach final position will help to shorten the
landing run if one is landing with the engine extended.
WARNING:
you may control the descent of the aircraft when flying the landing pattern.
However, before entering any turn, close the dive brakes. Flying with the dive brakes
extended when the aircraft is in a turn is not recommended.
4.10 INSPECTION BETWEEN FLIGHTS
The following must be checked:
1.
Engine and its mounting brackets
2. Propeller
3. Fuel
system
4. Undercarriage
5. Cockpit
