4.4.7
Flights in rain and thunderstorms
Rain drops, frozen fog and ice cover may change the wing section
characteristics to such an extent, that flight characteristics will decrease.
The minimun stall speed rises considerably. Therefore the approach speed
must be increased.
Warning:
Flights and especially winch launches in the vicinity of thunder
storms must be avoided. In case of a lightning strike the composite structure
may be damaged or destroyed. The sailplane is not equipped with a lightning
protection system.
4.4.8
Cloud flying
Cloud flying is only permitted without waterballast!
Take care to fly smoothly and coordinated. It is prohibited to use a spin as a
method for loosing altitude in cloud. In case of emergency, pull out the
airbrakes fully before exceeding a speed of 170 km/h and dive with max.
170 km/h (92 kts.) to leave the cloud.
At higher speeds up to V
NE
pull out the airbrakes very carefully because of
high aerodynamic and g-loads.
You may extend the landing gear in addition to increase the sink rate.
Warning:
Flight in thunderstorm clouds is prohibited.

Aerobatic manoeuvres are prohibited
