PART IV-EMERGENCY HANDLING

     91.  Ditching

     (a)  Model tests indicate that except in calm sea and air
          conditions the pilot should bale out rather than attempt
          ditching.

A.L.1     91A. Landing with an undercarriage unit not locked down
Page 79          NOTE:-Experience has shown that these techniques cause minimum
                               damage to the aircraft and none to the pilot.

            (a)    Both main wheels only locked down
                      (i)  Use up as much fuel as is safe in order to move the C. of G. as
                           far aft as possible.  Unless circumstances dictate otherwise land
                           on a runway.
                           
                     (ii)  Check harness tight and locked.
                    (iii)  Select hood open when crossing the threshold.
                    (iv)  Make a powered approach at the normal speed; on touch-down
                           turn the H.P. cock off and maintain a moderate nose-up attitude.
                     (v)  Trim the tailplane to give full nose-up trim and as the speed falls
                           below 100 knots maintain a high nose-up attitude without
                           actually touching the tail cone on the ground.
                    (vi)  When the nose drops on to the runway at approximately 80 knots
                           use the brakes gently to keep straight.
                           
            (b)    Nosewheel and one main wheel locked down
                    If all attempts to lower the undercarriage satisfactorily fail and only
                    the nosewheel and one main wheel come down, make a normal
                    approach and landing; on touchdown turn the H.P. cock off and
                    hold the wings level for as long as possible by use of the ailerons.
                    When aileron is applied and when the wing finally drops, the aircraft
                    will swing in the direction of the unlocked wheel; this should be
                    counteracted as much as possible by opposite brake.  Experience has
                    shown that the distance from the landing path to the point of rest
                    averages approximately 250 yards, varying from 100 yards (min.) to
                    400 yards (max.).  A runway should be chosen which has an area about
                    400 yards wide available in the direction of the anticipated swing.
                    
            (c)    Belly landing
                    If it is necessary to land with the undercarriage retracted, make a
                    normal approach and fly the aircraft gently on to the runway at the
                    normal speed.
