PART III - HANDLING

       (ii) Check the engine instrument readings while at full
            power.  If the j.p.t. is less than 675°C. the take-off should
            be abandoned.
       (iii)Release the brakes, using them as necessary to keep
            straight until rudder control is obtained at about 50
            knots.  The nosewheel steering must not be used during
            the take-off or landing run except in the case of a burst
            tyre, or any similar emergency when it is otherwise     A.L.1
            impossible to keep straight.              
       (iv) At about 95 knots ease the nosewheel off the ground and
            thereafter maintain a steady progressive backward move-
            ment of the control column until the aircraft flies off
            at about the speed shown below.  If trimmed for take-
            off on the forward limit of the trimming indicator light,
            the forces required to raise the nosewheel and unstick are
            high.  They are not so marked when trimmed at the aft
            limit of the trimming indicator light:-
                           Weight                 I.A.S.
                          13,000 lb.             105 knots
                          15,000 lb.             115 knots
                          17,000 lb.             125 knots
	            
       (v)  The aircraft unsticks, not very cleanly, in a pronounced nose-up
A.L.2              attitude which becomes less as the speed builds up and the flaps
Para. 56           are raised.  The difference in take-off run between using flap
(v) to (x)           and half flap is less than 5 per cent. at all loads.

            (vi)  When definitely airborne apply the brakes and raise the under-
                  carriage.  Raise the flaps at 150 knots; any tendency to sink is
                  easily held.  Return the flaps lever to neutral when the flaps
        |         are up.  At light loads the speed builds up rapidly, and if full
        |         flap is used for take-off, it is easy to damage the flaps by exceed-
        |         ing the limiting speed of 175 knots before they are fully up.
        |   (vii) If the undercarriage doors do not close, after the legs have
        |         retracted, the EMERG UP button may be used to close them.
        |         A visual check from the Control Tower or a formating pilot
        |         must be made to ensure that the legs are fully retracted before
        |         the button is pressed.
            (viii)Trim as required.  If trimmed for take-off top the aft limit of the
                  trim indicator light there is a fairly strong nose-up change of
                  trim as the speed increases and the flaps are raised.  The change
                  of trim is less marked if the forward limit of the trim indicator
                  light is used for the take-off setting.  On aircraft from XB801
                  the rate of movement of the tail trimmer is slower and the take-
                  off trim position is fully aft.
            (ix)  When at a safe height, switch OFF the emergency fuel switch
                  (if used) while still at full throttle.
            (x)   The slats will close at about 180 knots.
