PART 1-DESCRIPTIVE

   (b)  Oil system

 	Oil is carried in the engine sump, the oil capacity of which
 	is 10 pints.   One pressure pump maintains a continuous
 	circulation through a filter to the engine and aircraft
 	accessories and to three two metering pumps which supply  AL.1
 	oil to the front and rear bearings and the governor.        AL.1
                                             

   9.   Throttle control

   (a)  The throttle levers (5) move in quadrants marked SUT-
        THROTTLE-OPEN one on each pilot's engine control
        box. 

   (b)  A jet pipe temperature gauge and an r.p.m. indicator are
        mounted on the left of the instrument panel.

 	        
   10.  H.P. fuel cock
   
        The high pressure fuel cock is controlled by a lever (3)
        marked OPEN (forward)-SHUT (aft) situated inboard
        of the port throttle lever.   This lever should always be
        used to stop the engine.

   
   11.  Engine starting system

   (a)  The engine is started by an electric motor which rotates
        the engine to the required light-up and self-sustaining
        speed.   The circuit for the electric current supply is
        controlled by the interlinked starter and master switches
        (32) at the lower centre of the instrument panel and the
        starter circuit-breaker.   The starting sequence is con-
        trolled entirely by a clockwork time switch.

   (b)  The time switch is fully wound initially by pressing the
        starter button for about two seconds.   When the button
        is released, current is supplied to the starter motor.
        After 4 to 7 seconds, during which time the engine is
        rotated slowly, the starter motor accelerates the engine
        to a suitable r.p.m. (700-900) for light-up.   At this speed
        the igniter plugs light up the fuel and the starter motor
        further assists the engine in acceleration.
