
Strong pitch buffet as the incipient stall is entered
 A tendency to roll or wing rock accompanying the buffet
To recover normal operating airspeed at the slow flight stage, simply
move the stick forwards and apply power.
4.17.2 Wings Level, Power Off The aircraft can safely be stalled at a
deceleration rate of up to 3kn/s. Max pitch attitude is 45
0
, and stall
warning is given about 5 knots above the stall by buffet. Stall is
normally marked by a mushing descent in heavy buffet or nose drop.
4.17.3 Recovery is effected in the standard manner by moving the stick
forwards to reduce angle of attack and simultaneously applying full
power. The nose can then be raised as soon as the airspeed is building
past 45 – 50 knots CAS [ IAS]. Height loss between stall and
recovery, if well executed, is around 50 feet ft if power is used, or
around 100 feet to establish a steady glide if power is not used.
4.17.4 Wings Level, Power On Characteristics are similar to the power off
case. An additional warning of the approaching stall is the attitude of
the aircraft. With full power set the aircraft stalls at a very high nose
attitude.
4.17.5 Because of the increased slipstream and torque effect at high power
settings considerable rudder deflection may be required to keep in
balance as the stall is approached. Stalling out of balance can result in
considerable wing drop.
4.17.6 Recovery is simply effected by moving the stick forwards to reduce
angle of attack. Any tendency to wing drop should be countered by
application of opposite rudder sufficient to prevent further yaw
towards the dropping wing. These two actions should be performed
simultaneously.
4.17.7 In Turning Flight Stalling speeds are increased with bank angle, in
the manner normally expected. The Skyranger often has the
characteristic of rolling towards wings level as the stall occurs.
Recovery is standard. Move the stick forwards to reduce angle of attack
and apply power. Simultaneous opposite rudder should be applied
against any rolling tendency. Once the aircraft is safely above the
stalling speed co-ordinated aileron and rudder can be used to level the
wings.
