PART II-HANDLING

                the tail may touch the ground.  The aircraft should be
                flown off at about 110 knots.  When flying at the maxi-
                mum all-up weight, the above speeds should be increased
                by about 5 knots.
          (v)   When comfortably airborne brake the wheels and then
                retract the undercarriage.
          (vi)  (a)  When carrying wing drop tanks or 1,000 lb. bombs
                     the airflow at high speed may prevent the under-
                     carriage doors closing; the undercarriage should,
                     therefore be retracted as soon as the aircraft is com-
                     fortably airborne and before a speed of about 130
                     knots is attained.  If the indications show that the
                     undercarriage is not fully retracted, use of the hand-
                     pump and yawing of the aircraft at about 140 knots
                     should succeed in locking it up.  If this is unsuc-
                     cessful, select undercarriage down again and climb
                     to a safe height keeping the speed below 175 knots;
                     then reduce speed as far as practicable and select
                     undercarriage up.
                (b)  If the solenoid lock sticks and prevents the selector
                     lever from being raised, it can be over-ridden by
                     operating the undercarriage emergency retraction
                     switch.
          (vii) Raise the flaps (if used) and throttle back to climbing
                r.p.m.
          (viii)Turn on the canopy seal.
          
          31.   Climbing
          
          (i)   The speeds for maximum rate of climb at 10,200 r.p.m.
                are 260 knots at sea level, decreasing by about 15 knots
                for every 10,000 ft. increase in altitude up to 30,000 ft.
                Above 30,000 ft. decrease speed by about 45 knots for
                every 10,000 ft. increase in altitude.  With external equip-
                ment slightly lower speeds should be used.
          (ii)  If for any reason maximum power cannot be used with-
                put exceeding jet pipe temperature limits, the r.p.m.
                should be reduced accordingly.
          (iii) During the climb the cockpit pressure warning light will
                come on at approximately 17,000 feet.  The cockpit
                pressurising lever should then be turned on and the warn-
