Comments
- Engine relighting in flight is only guaranteed within the envelope
and always necessitates starter assistance- The power may be restored immediately after relighting providing TOIL > O°C.
- Should the engine fail to light up within 10 seconds, select fuel to shut off, the ignition OFF and allow engine to be ventilated for 30 seconds minimum prior to making another attempt.
ENGINE FLAME OUT
Comments
- Shut down the engine is no immediate relight- The causes of engine flame out can generally be divided into two categories:
- External causes such as icing, very heavy turbulence, fuel mismanagement.
Theses causes, which may affect both engines can generally be easy determined and an immediate relight can be attempt.
- Internal causes which as engine stall or fails usually affect a single engine and are not so easily determined, In these cases, the engine is shut down then the cause of the flame out investigated. If it cannot be positively determined what caused the flame out, the need for engine restart should be evaluated against the risk of further engine damage or fire may result from aa restart attempt.
- If damage is suspected, as precautionary measure, the FIRE handle is pulled.
