ENGINE MALFUNCTION Flashcards
1
Q
ENGINE MALFUNCTION
If possible, should the flight crew keep the engine running? And why?
A
- YES, except if a procedure requires an engine shutdown.
- Even at idle, the engine powers the hydraulic, electric, and bleed systems.
2
Q
TAILPIPE FIRE
When can an engine tailpipe occur and why does it occur?
A
- An engine tailpipe fire can only occur at engine start or at engine shutdown.
- It is the result of an excess of fuel in the combustion chamber, in the turbine or in the exhaust nozzle, that ignites.
3
Q
TAILPIPE FIRE
What is the correct way to deal with a tailpipe fire?
A
- Stop the fuel flow and ventilate the engine.
4
Q
TAILPIPE FIRE
In this case, is there a cockpit indication?
A
- The only indication can be an increasing EGT due to the fire in the turbine.
5
Q
TAILPIPE FIRE
Which procedure do you ask for?
A
- QRH ENG TAILPIPE FIRE
6
Q
TAILPIPE FIRE
Should you use the ENG FIRE pb? Why?
A
- NO.
- This cuts off the electrical supply of the FADEC, and stops the dry crank sequence performed by the FADEC.
7
Q
TAILPIPE FIRE
Should you use the fire extinguisher?
A
- NO, as it does not extinguish an internal engine fire.
8
Q
ENGINE VIBRATIONS
Which procedure can you refer to if no ECAM?
A
- QRH HIGH ENGINE VIBRATION
9
Q
ENGINE VIBRATIONS
When can you suspect if the vibrations are due to ICING?
A
- If N1 vibrations occur without variation on other engine parameters.
10
Q
ENGINE VIBRATIONS
If you suspect ICING, what should you do?
A
- Disconnect the A/THR
- Performs several large thrust variations from idle to a thrust compatible with the flight phase.
- It may be necessary to perform several engine run-ups (decrease and then increase of thrust) to fully shed the ice.
11
Q
ENGINE VIBRATIONS
What can you do to reduce vibrations?
A
- If flight conditions permit, reduce thrust to make the vibrations decrease, and stay below the ECAM alert and ECAM advisory threshold.
