Eiri KY PIK-20 E - Cloud Flying; Flying in the Rain

PIK-20 E Flight manual
The spin is possible at all C. of G. positions. However, with the fo 
reward C. of G. the sailplane will spin only two or three turns. Entry and
control positions are normal (pulled stick, central aileron and rudder in
spinning direction). Recovery is normal by neutralizing the controls.
Use airbrakes if the speed tends to increase too much during recove 
ry.
The altitude loss is less than 90 m (300 ft).
Note: Drain the water ballast before aerobatic maneuvers.
5.24 Cloud flying
Minimum instrumentation required during the cloud flying is described
in chapter 3: "Limitations":
Do not exceed the rough air speed limit. In severe turbulence less speed
should be used. Extend the airbrakes if the speed tends to increase too
much.
Observe icing.
5.25 Flying in the rain
Raindrops, ice or frost on the sailplane's surfaces will considerably redu 
ce its performance. The stall speed increases 10 to 20 percent and the
rate of sink is also greater then normal.
This must be taken into account particularly during the takeoff, app 
roach
and landing. Especially during the takeoff with engine the wing
should be clean to assure the performance given in the performance pa
ragraph.
The rain will also wear the leading edge of the propeller. Take 
off in the rain is prohibited.
The gliding performance of the sailplane in the rain is improved if the 
re is no wax on the wing surfaces.
