Ventus-3M „Performance“ FLIGHT MANUAL

Revision – 4.5.3.6
Turning flight stalls
When stalled during a coordinated 45° banked turn and 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 to
spin.
In a forward c/g position, the aircraft just stalls without dropping its nose or
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 time of correction of the stalled flight condition
and can be between 60 m and 150 m (200-500 ft).
Influence of Water Ballast
Apart from higher stall speeds - caused by the higher mass in flight - water
ballast in the wing tanks has no negative influence on the stall characteristics.
The loss of height from the beginning of the stall until regaining a normal level
flight attitude can be up to 150 m (500 ft).
With water ballast in the fin tank (option), stall characteristics are like those
found at aft c/g positions.
