     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.
