3.5.2 Glider-Configuration
Stall speed depends on flap-setting and actual weight and may occur in
unaccelerated level-flight below 52 kts / 96 km/h (worst for flaps set to CRUISE
at maximum weight). Stalls will occur in turns at higher speeds depending on g-
force. In soaring-flight an aerodynamic buffeting warns against the stall.
If the angle-of-attack is increased while aerodynamic buffeting occurs – or if a
turn is then flown – a wing-drop may occur. Depending on the CG-position,
afterwards the A/C may spin.
Stall Recovery in glider configuration:
1. Elevator RELEASE back-pressure,
3. Attitude CORRECT to normal flight
Warning: When recovering from a stall in horizontal flight, an altitude-
loss of 100 ft / 30 m is possible. In turning flight, an
altitude-loss of 130 ft / 40 m is possible. If the pilot
reactions are delayed, the altitude-loss may be more than
200ft / 60 m.
