69. Stalling
(a) Due to the positioning of the pitot head there is consider-
able fluctuation of the airspeed indicator at the stall.
The following table of stalling speeds in therefore only
approximate.
Typical Max.
Service A.U.W.
Load
Knots Knots
Undercarriage and flaps UP 95 105
Undercarriage and flaps down 85 95
(b) Warning of the approach of the stall is given by slight
elevator buffeting commencing about 15 to 20 knots
before the stall and increasing as speed is reduced. At
the stall the nose drops gently. There is little tendency
for a wing to drop at lower altitudes, but at heights above
20,000 feet this tendency becomes more marked and if
the aircraft is held in the stall it will roll in either direction
into an inverted position.
