Revision – 4.5.3.6
Turning flight stalls
When stalled during a coordinated 45° banked turn with the c/g at an aft
position, the aircraft rolls slightly into the turn and, when easing the stick
forward, slightly drops its nose and a normal flying attitude is regained by
applying opposite rudder and aileron. There is no uncontrollable tendency for
the powered sailplane to enter a spin.
With the c/g in foremost position, the aircraft just stalls without dropping its
nose or a wing.
Normal flying attitude is regained by applying corresponding control
deflections.
The loss of height from the beginning of the stall until regaining a normal level
flight attitude depends on the prompt response of the pilot and is between 60
and 150 m (197 to 492 ft).
Influence of water ballast
Apart from the higher stall speeds due to the higher mass in flight, water
ballast in the wing tanks has no aggravating influence on the stall
characteristics.
The loss of height from the beginning of the stall until regaining a normal level
flight attitude is up to 150 m (492 ft).
With water ballast in the (optional) fin tank, the stall characteristics are like
those found for aft c/g positions
