Eiri KY PIK-20 E - Approach and Landing

PIK-20 E Flight manual
A
Stall speeds for various flap angles and weights are given in chapter 7
"Performance".
Extending the airbrakes increases the stall speed about 8 km/h (5
mph, 4 kts), see 7.1.
5.20 Approach and landing
The landing is recommended to be made with the water ballast drained
and
the engine retracted. The flaps should be deflected down +12° to
+ 16°. Negative flap angles should not be used because of high stall
speed. The trim is a little foreward from the central position.
Airbrakes can be used as desired. The approaching speed is 95 km/h
(59 mph, 51 kts) with 370 kg weight and 105 km/h (65 mph, 57 kts) with
470 kg weight.
On ground the wheel brake can be used as desired.
In strong crosswind +8° down deflected flaps and a slightly higher
approaching speed can be used.
When landing with the engine extended and idling, the airbrakes
should not be used fully open near the ground because of the great rate
of sink.
To avoid damages to the landing gear doors when landing on soft
ground or in long grass, it is possible to keep the landing gear retracted.
For inspection after a belly landing, see Service Manual.
If the ground run is going to be too long, it is possible to push the
nose down at the same as using the wheel brake to stop the sailplane
better.
Note: A wet wing increases the stall speed and rate of sink.
