             MANAGEMENT OF SYSTEMS

	      AND USE OF EQUIPMENT


         52. Management of the fuel system
       
         (a) The internal tanks and the wing drop tanks all feed the
             engine automatically when the low and high pressure fuel
             cocks are on.
--------------------------------------------------------------------
Page 32  (b) The booster pump must be switched ON before starting
Para. 52       and left on at all times when the engine is running. The
(b)              fuel pressure warning light will come on when pressure
A.L.3           is low, indicating that there is a fault in the system or
                  that the booster pump is switched off. The engine will
                  run satisfactorily with the booster pump off below 20,000 ft.
                  but above this height, full power may not be obtained.
                  Avoid harsh throttle movements and negative G.
------------------------------------------------------------
         (c) Transfer of fuel from the wing drop tanks into the
              fuselage tanks begins when approximately 120 lb. have
              been used from the fuselage tanks.
              

         53. Engine handling
         
         (a) Engine control

              (i) Throttle movements should be made slowly to avoid
                  resonance and high jet pipe temperature. When
                  Goblin Mod. 1130 is incorporated the engine may be
                  throttled fully back at any altitude, the minimum
                  pressure valve ensuring that burner pressure does
                  not fall too low to support combustion; the idling
                  r.p.m. are therefore increased with altitude.

             (ii) Cases have occurred of flame-out or near flame-out
                  (burbling) at altitude when carrying out manoeuvres
                  involving a stall. This is due to a combination of
