Flying at High Speed
Within the permitted speed range the glider has no tendency towards high speed flutter.
The controls need only be used at 1/3 of their full movement at 93 kts. The air brakes are
speed limiting and with them open the glider will only reach about 108 kts even in a 45°
dive.
Approach and Landing
The glider can be brought in quite normally at an approach speed of 50 kts. The air-
brakes allow a steep approach to be made quite easily. As the action of the brakes makes
the glider slightly nose-heavy, the machine will itself maintain the airspeed it is set at
when the brakes are
opened. The sideslip is quite controllable and, if needed, this
manoeuvre can be used to help land the glider.
ATTENTION:
Landing circuit check:
Height 500 ft.
Airspeed 50 kts.
WHEEL DOWN AND LOCKED
Flying in rain
A thin layer of water or ice on the wings leads to no deterioration in
the flying
characteristics of the glider. With more substantial deposits the stalling speed is
increased by about 3 kts, although the way the glider takes off and touches down
remains the same. Increase the normal flying speed accordingly.
Cloud-flying
The minimum set of Instruments required before cloud flying should be attempted is:
A.S.I., Altimeter, Compass, Turn and Slip Indicator and Radio
The A.S.I. must have the maximum permitted speed marked on it, i. e. red section.
In order to avoid exceeding the maximum permitted speed, the airbrakes should be
opened in good time (i. e. at about 86 kts.)
Warning:
Cloud flying and aerobatics should only be carried out by pilots who possess
the appropriate authorization. The statutory regulations must be adhered to.
