PART III - HANDLING
62. Stalling
(i) The stalling characteristics with or without drop tanks
are the same at all weights and irrespective of the posi-
tion of the undercarriage, flaps and air brakes.
(ii) As the speed is reduced, a mild buffeting commences
some 5-10 knots before the stall. This continues down
to the stall itself at which point it increases slightly in
strength. The ailerons and tailplane retain their normal
feel down to the stall.
(iii)At the stall the nose drops gently; with the control
column held fully back a gentle pitching motion com-
mences with the buffeting increasing each time the nose
rises. At all times full aileron control is available.
(iv) Recovery is made by easing the control column forward
and allowing the speed to increase, at the same time open-
ing the throttle as necessary. Little height is lost, but
while stalled, the rate of descent is high.
(v) Weight has a marked effect on the stalling speed and due
allowance must be made when flying at low speeds at
maximum weight.
(vi) Fractional amounts of G will result in noticeable
increases in the stalling speeds.
(vii)(a) At any time when G is applied, warning of the
approach of a stall is given by slight buffeting which
increases at the stall itself. During a turn at
moderate speeds and G loads, continued backward
movement of the control column will result in a
pitching motion which stops when the control
column is moving forward. If the control column is
moved further back, either wing may drop sharply
or the aircraft may flick.
(b) Whenever a manoeuvre involving high G is carried
out at high airspeeds the loading must never be
increased beyond the point at which buffeting com-
mences, otherwise, due to unstable characteristics
under these conditions, the aircraft will commence
to tighten up automatically and the G limit may be
inadvertently and easily exceeded. Therefore,
should buffeting commence while at high G loads,
reduce the loading and check any tendency to
tighten up.
(viii)The table below gives the stalling speeds at various air-
craft configurations and weight.
