4.5.7 Cloud flying
The spin should not be used as a safety escape outside a cloud, as
the sailplane may change over into a spiral dive.
It is rather recommended to open the air brakes fully at speed of
130 km/h IAS (70 KIAS, 81mph) and at load factor above 2 "G". At
speeds above 150 km/h IAS (81 KIAS, 93 mph) the air brakes
should not be closed, as this sailplane, owing to its very steep glide
path, may exceed the never exceed speed.
Minimum equipment for the cloud flying is listed in 2.10.
4.5.8 Flights below zero
The control system friction may increase when the temperature is
below zero degrees of Centigrade, as well as during winter flying.
Ensure that all control elements are free of moisture to prevent
freezing. This, in particular, applies to the AIR BRAKES.
Continuously operate controls and air brakes at short intervals.
During flights with water ballast, note the recommendation under
4.5.4.
4.5.9 Flight in rain
Neither any special actions are required when flying in rain nor the
flight characteristics are significantly affected.
