Taxying
        
(a)        Taxying is normal for nosewheel type aircraft.  Fuel consumption at idling r.p.m. is about 2 galls per minute.
(b)        The aircraft should not be taxied at a speed which requires excessive use of the brakes as this causes over heating of the tyres and reduces their life.

                                                                                            Warning light out.
                  
Take-off
    
 (a)           Align the aircraft and roll forward a few yards to straighten the nosewheel.  
               Apply the brakes with rudder bar central and open the throttle smoothly. 
               If the brakes do not hold at 6,800 r.p.m. they should be considered unserviceable and the aircraft should not be flown.
               Release the brakes and open the throttle fully, checking the engine operation.
 
(b)           In cross wind conditions, gentle braking is necessary to keep straight until the rudder becomes effective.
         
(c)            Ease the nosewheel off at about 125 knots and hold it just off the runway, 
               taking care not to achieve an excessively nose-up attitude. At normal loads the aircraft will unstick at 150 knots.
         
(d)           When comfortably airborne apply the brakes and raise the undercarriage holding the brakes on until the undercarriage is locked up. 
               There is no noticeable change of trim as the undercarriage retracts but the nosewheel locks up with a distinct thud. 
               It may be necessary to climb quite steeply initially as retraction must be complete before 250 knots is reached.
         
(e)            Until experience is gained the lightness of the flying controls may lead to over-controlling in both pitch and roll.
         
(f)  When carrying stores
        
Using 38° flap the nosewheel can be eased off at 125 knots and the aircraft flown off at 145-150 knots.  
When safely airborne immediately raise the undercarriage and then the flaps, 1 notch at a time retrimming after each selection; 
delay in raising the flaps will result in an increasing nose-down change of trim as speed increases.
         
 
Climbing
     
         NOTE.-If pressure has been set OFF for take-off,
               set it ON at 5,000ft.
 
Best rate of climb
 
(i)             Climb at full throttle at 0.85M.  Speed should be allowed to increase to the recommended figure during the initial climb to 5,000 feet. 
        
(ii)            Below 20,000 feet the rate of climb is not greatly affected by variation in speed, provided that it is maintained between 400 knots and 0.9M.
                
(iii)           Above 20,000 feet it is important to keep to the recommended speed; above 30,000 feet the rate of climb will fall off quickly if speed is reduced below 0.85M.
                
Normal climb
          
If maximum rate of climb is not essential set 7,800 r.p.m. using the same speed as above.
 
CIRCUIT PROCEDURE AND LANDING
 
Circuit procedure
        
NOTE-460 lb. (60 gallons) of fuel should be allowed for a circuit, landing and possible overshoot              
 
 (a)   Circuit speed
With the undercarriage lowered fully, 6,500 r.p.m. and 38° flap (four notches) give a comfortable speed of about 180 knots. 
To reduce speed for joining the circuit, flap, within the limitations, can be used successfully to augment the airbrake.  
Do not select more than one hydraulic service at a time and allow the cycle of each hydraulic operation to be completed before the next service is operated.  
The undercarriage should only be selected down with the wings laterally level.
 
 (b)   Checks before landing
        
               Airbrake                                                                IN, indicator black
               Undercarriage                                                        Down below 250 knots
                                                                                            Three green lights
               Brakes                                                                  Pressure, operation, off
                                                                                            Main supply 3,000±150lb./sq. in.
                                                                                            At each wheel 1,500 lb./sq. in.
               Flaps                                                                    As required
                                                                                            Fully down on finals
               Fuel                                                                      Contents
                                                                                            Booster-pumps ON
               Harness                                                                Tight and locked
              
                                   
(c)   Final approach
                    (i) Turn across wind at 160 knots aiming to lower full flap on the final stages.  Steep approaches are not recommended.
 
    (ii) To ensure most rapid engine response maintain at least 4,500 r.p.m. until finally committed to a landing.  
    Under conditions of high wind or gustiness it is more comfortable if the speeds below are increased by 5 knots.
                          
                    (iii)The recommended speeds, in knots, at the runway threshold:-
                     
                          At normal landing weight
                          No ammunition, 800 lb. or less fuel remaining            130
                          At maximum landing weight
                          No ammunition, 1,800 lb. fuel remaining                     135
                          Full ammunition, 1,100 lb fuel remaining                     135
------------------------------------------------------------------------------------------------------------
Landing
     
(a)            As the touch-down point is approached, the rate of descent should be checked and the aircraft flown gently on to the
               ground at about 5-10 knots less than the runway threshold speeds.  Holding off may result in an excessive nose-up 
               attitude with the subsequent danger of dropping a wing; if the latter occurs, corrective aileron may be effective in raising 
               the wing, but will cause the aircraft to yaw markedly in the direction of the down-going wing.  The nosewheel can be held 
               off at speeds down to about 70 knots, but the shortest run is achieved by putting the nosewheel firmly on to the runway 
               and applying the brakes.
(b)  Braking
     
                     NOTE.-The effectiveness of the braking system is greaty decreased
                           on very wet or icy runways.  If wind conditions are favourable
                           it may be advantageous to use aerodynamic braking.
                           
                     When the nosewheel has been lowered on to the runway the brakes
                     can be used continuously and the maxeret units will prevent wheel lock-
                     ing; however, to prolong the efficiency and life of the brakes brak-
                     ing should be judicious according to length of landing run available.
                     The landing can be cut to less than half normal by using continuous
                     full brake once the aircraft is firmly on the ground, but this procedure
                     causes rapid brake and tyre wear and should not normally be used.
                     The aircraft must be firmly on the ground before applying the brakes.
                     If it is allowed to touch down with the brakes on, the maxeret units
                     will not operate and the wheels will lock; however, if once having
                     started turning the wheels should stop because of skid or bounce,
                     they will not lock unless the skid or bounce continues for more than
                     4 seconds.  After a landing involving heavy braking, ten minutes
                     should elapse before the next landing.  If the intervening period of
                     taxying has also required prolonged use of the brakes, twenty minutes
                     should elapse before the next landing.  Observe the same precautions
                     in brake tests.  On wet runways the landing run may be decreased by
                     lowering the nosewheel on to the runway, applying the brakes and
                     pulling the control column right back.  The brakes must be in use
                     while the back pressure is applied.
 
      (c)  Cross-wind landing
               
           For cross-wind landings the "crab" technique should
           be used.  In light winds no difficulty should be exper-
           enced in touching down but in strong cross-winds full
           rudder may be required to correct the crabbing.  The
           rudder has a delayed reaction which will require anti-
           cipation.  The secondary effect of full rudder is to pro-
           duce a marked roll which must be counteracted with
           aileron.  When the crabbing has been corrected the air-
           craft should be flown gently on to the ground and the
           nosewheel then lowered on immediately, thus reducing
           the tendency for the cross-wind to lift the into-wind wing.
           Care should be taken to centralize the rudder before
           applying brake.  If the cross-wind is gusting strongly the
           approach speed should be increased by 5 knots.
