excessive water over 6 l will leak through the hole marked 6 l.
4.5.8 Cloud flying
Cloud flying is prohibited.
4.5.9 High altitude flight
CAUTION
Keep in mind, that a difference between Indicated Air Speed (IAS)
shown by your airspeed indicator and True Air Speed (TAS) is
increasing with an altitude increase.
This has no influence on the sailplane strength or load, however
due to flutter safety the IAS limits shown in table below must not be
exceeded in given altitudes.
