DUAL ENGINE FAILURE Flashcards
1
Q
What is the purpose of the ENG ALL ENGINES FAILURE ECAM procedure?
A
- Secure automatic extension of the RAT
- Secure the automatic connection of the emergency generator.
- Guide the flight crew to apply the ALL ENGINES FAILURE QRH procedure.
2
Q
If one or more engines relight:
A
- Apply the corresponding ECAM procedure instead
3
Q
If none of the engines relights:
A
- Continue to apply the ALL ENGINES FAILURE paper procedure. If there is sufficient time, clear both the ECAM alerts and the ECAM STATUS page.
4
Q
If there is sufficient time to attempt an engine relight:
A
- Apply the ALL ENG FAIL QRH procedure.
5
Q
If there is not sufficient time to attempt an engine relight:
A
- apply the EMER LANDING QRH procedure.
6
Q
What is the total flight time on batteries?
A
- 30 minutes
7
Q
By how much time does an APU start attempt reduce battery life?
A
- about 3 and a half minutes
8
Q
What may the PF do in order to balance out a roll moment from hydraulic pressure lost?
A
- PF may use the rudder trim to generate sideslip and therefore compensate for this upfloating aileron.
9
Q
Key things about DUAL ENG FAIL?
A
- AP, FD, and A/THR are lost
- Aircraft operates in alternate law
- F/O PFD and F/O ND are lost.
10
Q
While descending and flying closer to the windmilling speed, what should you consider?
A
- In alternate law, the overspeed protection is lost and the aircraft speed and Mach upper limits are reduced.
11
Q
Is there a limitation for windmilling start attempts?
A
- Regardless of the relight procedure (Windmill, or using the APU bleed), engine master levers must be set to OFF for 30 s in order to ventilate the combustion chamber of the engine between two relight attempts.
12
Q
What should you do if the first windmilling relight attempt is unsuccessful?
A
- Repeat windmill relight attempts on all engines until successful.
13
Q
Is there a limitation for bleed assisted start attempts?
A
- If the APU bleed is used, the flight crew can attempt a relight on only one engine at a time.
