PART II-HANDLING
          
                    widely.  Continued backward pressure on the con-
                    trol column results in stronger buffeting and an
                    increased tendency for either wing to drop.  With
                    power on there is less warning of the approach of
                    the stall but the characteristics are unaffected.
                (c) The dive brakes do not noticeably affect the stalling
                    speeds or characteristics.
          (iv)  At all loads, warning of the approach of the stall in a
                steep turn or in recovery from a dive is given by elevator
                buffeting and at the stall the aircraft may flick in either
                direction.  Stick forces are light and it is relatively easy
                to stall the aircraft at low speeds in a steep turn then particu-
                larly at high altitudes with loadings near the aft C.G.
          (v)   Recovery in all cases is normal and immediate.
                
         38.    Aerobatics

          (i)   The following speeds in knots are recommended :-
                    Roll	...	...	...	230-250
                    Loop	...	...	...	300-320
                    Half roll off loop	...	...	320-340
                    Climbing roll	...	...	340 plus
          (ii)  Aerobatics are prohibited when carrying external stores
                or wing drop tanks (either full or empty).
          (iii) In manoeuvres in the looping plane stick forces are light.
                Much height may be lost or gained and an ample mar-
                gin should always be allowed for recovery in normal
                flight.
          (iv)  The negative "g" valves in the fuel collector box ensure
                a supply of fuel for not more than 10 seconds inverted
                flight.
                
         39.    Approach and landing

          (i)   Carry out the checks detailed in the Pilot's Check List,
                items 103 to 110.
          (ii)  At the maximum landing weight 10,560 lb. (with or with-
                out external stores) the recommended final approach
                speed with full flap is 95-100 knots.
          (iii) The initial approach should be made some 15-20 knots
                above this figure.
          (iv)  It is recommended that a powered approach be made,
                especially when landing with external stores, in order
