Eiri KY PIK-20 E - Stalls

PIK-20 E Flight manual
Unlock the cranking lever and extend the engine by turning fifteen
turns clockwise. The lever has to be left in such position that the safety
cable is tautened.
When the door/brake lever is moved forward the propeller should ro 
tate slowly in the air. This can be checked in the mirror.
When starting the engine the main switch should be on. Turn ignition
and electric fuel pump on. Adjust the choke 3/4 open, if the engine is
cold. The throttle should be opened about 1/4. The engine needs now
only a kick with the starter and the propeller will then rotate by itself in
the airstream. Adjust the choke and throttle when the engine is running.
If the battery is dead or if there is some other reason not to use the
starter, the engine can be started by windmilling. The speed required to
get the propeller rotating (windmilling) is about 165 km/h (103 mph, 89
kts). When the propeller once is rotating, it can be stopped only by re 
ducing speed and using the brake.
The altitude required to extend and start the engine is normally 60 to
30 meter (200 to 100 feet) when using the starter. In an outlanding this
operation can be made safely on the downwind leg. The height in the
beginning of the downwind leg should be at least 300 m (1000 ft) to give
time enough if something goes wrong. If the engine does not start it is
possible
to land with the engine extended.
The flight should be planned as a flight with a sailplane without an
engine. There should always be the possibility to land and one should
not go down over an area unacceptable for outlandings. There is always
the possibility that the engine does not start, especially when one tries
to start the engine in a rush above a forest or rocky area.
5.19 Stalls
In stall the nose drops without stall warning with retracted airbrakes.
With airbrakes extended stall warning is noticed about 10 km/h (6 mph,
5 kts) before the stall. With the engine extended one wing may drop
slightly. The altitude loss is about 12 to 6 m (40 to 20 ft). When stalled in
a 45° banked turn with the engine and airbrakes extended, the loss of
height may be 60 m (200 ft).
