i.
Demonstrate a stall from straight and level
using a small amount of power up to the
stall. Attempt to level the wings with aileron at
the stall.
Note: To demonstrate how the use of aileron
may aggravate the wing drop. It may be found
that on certain aircraft a convincing
demonstration cannot be made as the dropped
wing may be picked up with aileron. In such
cases, the demonstration may have to be made
with flaps down to prove that the use of aileron
at stall recovery can aggravate the wing drop.
EFFECT OF POWER ON THE STALL
Demonstrate a stall from straight and level using
an appropriate power setting up to the stall.
EFFECT OF FLAP ON THE STALL
Demonstrate stalls from straight and level with
Optimum flap and then with full flap, using no
power. During the recovery, do not exceed the
maximum flap extension speed.
,
i Entry procedure as per 4(i).
ii Recovery when wing drops.
a. Simultaneously apply:
Opposite aileron to pick up the dropped
wing. Control column sufficiently
forward to unstall the wings. Apply full
power.
iii Note:
a. Aileron input tends to aggravate the
wing drop.
b. Emphasise the importance of using
rudder.
i Lookout.
ii Entry:
a. Complete pre-stall checks.
b. Maintain throttle setting at cruise power
and ease nose up, keeping straight.
iii. Symptoms of the approaching stall:
Attitude – Nose position higher.
Speed – Decreasing slower.
Control effectiveness – elevator and rudder
more effective.
Stall warning – shorter duration.
Buffeting – Less noticeable.
iv. Symptoms at the stall;
a. Sink – Less.
b. Pitching moment – more abrupt.
c. Tendency to drop a wing.
d. Note: Speed.
Less altitude loss than for a
power off stall.
v. Standard recovery technique.
Complete after take-off checks – clean up once
established in the climb.
i. Lookout.
ii. Entry:
iii. Symptoms approaching the stall:
Attitude – compare with power off stall.
Speed – decreases rapidly.
Control effectiveness – note effectiveness of
elevator and rudder.
Stall warning – shorter duration.
Buffeting – less pronounced or absent.
iv. Symptoms at the stall
a. Sink – more pronounced.
b. Pitching moment – more pronounced.
