Stalling
The aircraft exhibits mainly benign stall characteristics. Natural stall warning is
given by mild airframe buffet and light vibration on the elevators. The quality
of the warning varies with aircraft configuration, decreasing in amplitude and
margin with progressive extension of the flaps.
Artificial warning is given by a warning horn that activates 5 to 10 kts above
stall speed. The approximate stalling speeds at an operating weight of 990 kg
for both Normal and Alternate static sources are:

The stall in the turn is indicated by moderate buffet and a tendency for the
aircraft to roll to the right irrespective of the direction of turn.
Recovery from the stall in all cases is straightforward. Releasing the
backpressure on the control column produces an immediate recovery.
WARNING
Use of the rudder whilst stalled will cause the aircraft to depart.
