   5.   Fuel transfer system

 	Fuel from the internal wing tanks is fed by gravity to
 	the fuselage collector box.   Fuel from the drop
 	tanks is transferred to the fuselage tank by air pressure
 	from the engine.   The transfer commences when about
 	120 pounds have been used from the fuselage tank, the
 	rate of transfer being controlled by a float-operated valve
 	near the top of the tank.                             
                                             
 	   
   6.   Fuel system

   (a)  An electrically-driven booster pump, in the fuselage
        tank collector box, delivers fuel through the L.P. cock
        and filter to a single engine-driven H.P. pump.   The
        booster pump is controlled by a switch (49) below the
        turn and slip indicator.   A red light below the selector
        dimer control (17) comes on when the pump is switched
        off or when pressure from the pump is below a satisfactory
        minimum.

   (b)  From the H.P. pump fuel is delivered through the throttle
        and H.P. cock to the engine.
 	    	        
   7.   L.P. fuel cock
   
        The low pressure fuel cock is controlled by a lever (17)(7) AL.1
        marked FUEL OFF (aft)(down) FUEL ON (forward)(aft) AL.1
        situated under then engine controls box on the cockpit
        port wall.   On no account should this control be used to
        stop the engine except in an emergency.

   8.   Goblin Mk. 3 engine
         
   (a)  General

        The engine is a centrifugal gas turbine developing 3,200 lb.
        static thrust at seal level.   The main engine systems
        include:-
        
             An electric starting system (see para. 11).
             Relighting facilities (see para. 12).
             A high-pressurised fuel system monitored by a baro-
               metric pressure control.
             Self-contained oil system.
