         HANDLING IN FLIGHT
    
    57.  Climbing
    
    (a)  Climb at full power within the j.p.t. limitations.  The
         following climbing speeds are recommended with or with-
         out drop tanks fitted:-
              300 knots until 0.63M is obtained, then 0.63M for the
           remainder of the climb.
         
    (b)  If maximum rate of climb is not essential, the climb should
         be made at 14,200 r.p.m., using the same airspeeds.  Throttle
         adjustment will be necessary to maintain this power setting.
         
    (c)  Particular care must be taken to maintain the correct
         climbing speed at altitude, or a considerable increase in
         time to height will result.
    
    58.  General flying
         
    (a)  Flying controls
          (i)  Ailerons. On aircraft fitted with geared tabs only, the
               aileron feel becomes progressively heavier with in-
               creasing airspeeds and mach numbers.  When spring
               tabs are fitted, the ailerons are light and pleasant but
               become heavier with increase in mach numbers.  Large
               control column movements are required for effective
               control at low I.A.S.

          (ii) Elevator. The elevators are effective and sensitive
               throughout the speed range.  At low airspeeds they
               become less sensitive but are effective down to the
               stall.
               

          (iii)Rudder. Control forces on the rudder become very
               heavy at high speeds and with large deflections at low
               speeds.  Sustained asymmetric flight at low I.A.S. is
               very tiring.

    (b)  Trimming controls
         NOTE.- The elevator and rudder trimmers may ice up at
                height.  Exercising the trimmers at regular inter-
                vals will help to prevent this happening.  If neces-
                sary, reduce height until they can be freed.

         (i)  Elevator trimmer.  The elevator trimmer is spongy in
              operation but very effective and the aircraft is easy to
              trim under most conditions of flight.
