                         EMERGENCY HANDLING


        79.  Engine failure in flight

        (a)  Mechanical defect
 
             If the engine faits due to an obvious mechanical defect,
             set:-
             Throttle				SHUT.
             H.P. and L.P. cocks		SHUT.
             Booster pump			Off.
             Non-essential electrical ser-	Off.
                vices
             Do not attempt to relight.

        (b)  Sudden drop in engine r.p.m.

             If a sudden inexplicable drop in engine r.p.m. occurs,
             close the throttle and set the isolating switch ON. (If
             the isolating switch is not switched to ON within 4
             seconds there is a probability of flame extinction.) Once
             the switch has been set to isolate it must be left there
             and the engine opened up slowly to the desired r.p.m.
             Idling r.p.m. will be high and landing must be carried
             out with caution.

        (c)  Flame out

            (i)  Should the failure be caused by mishandling, set:-
                 Throttle			SHUT.
                 H.P. cock			SHUT.
                 Non-essential electrical	Off.
                   services
                                                                 defect A.L.1
           (ii)  If flame-out occurs as a result of a fuel system deflect,
                 e.g., engine pump B.P.C. or from a servo system
                 defect proceed as at (i) above and switch ON the
                 isolating switch, leaving it on for the remainder of
                 the flight.
