    61.  Flying in severe turbulence

         The recommended speed for flying in conditions of severe
         turbulence is 215-225 knots up to the height at which this
         corresponds to 0.5M, i.e. up to about 20,000 ft. Above this
         height, 0.5M, should be maintained, providing this does not
         require and airspeed less than 195kts.
    
    62.  Stalling

    (a)  The appropriate stalling speeds (in knots), power off, are
         as follows:-

    (b)  Warning of the approach of the stall is given by:-

          (i)  Slight elevator buffeting some 10 knots before the stall,
               becoming more pronounced as the stall approaches.

          (ii) Slight fore and aft pitching accompanied by vibration
               before the aircraft stalls.

         At the stall, the nose drops gently and there is a slight
         tendency for either wing to drop, if the control column is
         held back.  Recovery in all cases is straightforward.

    (c)  With the airbrakes out, the stalling speeds quoted above
         are increased by 2-3 knots and the buffeting before the
         stall is more pronounced.
         
    (d)  G-stalling

         Onset of G-stalling is indicated by buffeting; continued
         rearward movement of the control column will cause more
         severe buffeting accompanied by a large loss of speed.
         Recovery is immediate when the back-pressure is relleased.
