4.16.1 Slow flight characteristics
Slow flight indications include:
 Lightening of controls accompanied by reduced effectiveness

Reduced airflow noise (most noticeable at low power settings)

High nose attitude (most noticeable at high power settings)
 Rearwards position of control stick and back pressure

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.
4.16.2 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 2 knots
above the stall by buffet. Stall is normally marked by a mushing
descent in heavy buffet or nose drop.
4.16.3 Recovery
Recovery should be made in the standard manner by moving the stick
forwards to reduce angle of attack, whilst simultaneously applying full
power to aid acceleration and minimise height loss. 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 - 80 feet ft if power is used, or around 100 - 150 feet to
establish a steady glide if power is not used.
4.16.4 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.
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.
