Eiri KY PIK-20 E - Glide; Restarting the Engine in the Air

PIK-20 E Flight manual
When the propeller is braked in the vertical position, the engine can
be retracted with the cranking lever. The lever is first unlocked by pul 
ling
the handle out towards the pilot and cranking is made counter 
clockwise.
After cranking fifteen turns the engine is retracted and slightly pres
sed towards the limiter in the rear fuselage. The doors can now be clo 
sed by moving the door lever forward. At the same time the engine is
locked
in down position. Because of the change in the C. of G. position,
the trim can be moved some notches forward.
If some extra resistance is felt during the retraction, the right position
of the propeller and the door lever should be checked.
To ensure proper braking of the propeller the tension in the brake
cable and the proper functioning of the brake should be checked daily.
5.17 Glide
In gliding flight with the engine retracted the sailplane is trimmed with
neutral flaps to fly about 100 km/h (62 mph, 54 kts). The trim is connec 
ted
to the flaps so that the optimum speed for a flap angle is automati 
cally achieved when the sailplane once has been trimmed. The optimum
flap angle with speed and other more detailed information and data are
given in chapter 7 "Performance".
Note that full aileron deflection is permitted only at speeds below the
maneuvring
speed (190 km/h, 118 mph, 103 kts). At higher speeds the
controls should be moved gently and any sudden movement to the op 
posite
direction should be avoided.
5.18 Restarting the engine in the air
The recommended speed when extending the engine in the air is 100
km/h (62 mph, 54 kts). Then there is no tendency of the propeller to ro 
tate during the extension if the brake is not in proper condition. The
maximum allowed speed is 135 km/h (84 mph, 73 kts).
Open the engine comparment doors by moving the door lever
backwards. The cranking lever cannot be moved when the doors are
closed.
