Generally, what flight levels are likely for the EO REC MAX?
FL180-FL350
After an engine failure in the cruise, how can you tell if you are above or below the EO REC MAX by looking at the ENG page?
If N1 gauges indicate that MCT is being commanded, this shows that the aircraft is using maximum available thrust, and hence you are above the EO REC MAX
Where is the EO REC MAX value displayed?
PROG page
What vertical mode is used for the drift down?
OP DES, until ROD less than 500fpm, after which V/S 500fpm used
What speed is flown in the obstacle strategy? Why?
Green dot
This is the lowest driftdown rate, and highest ceiling. It also reduces the chances that FADECs will try to autorelight the failed engine as the speed wont be in the envelope
What speed is flown in the standard strategy? Why?
M0.78/300kts
This speed is always in the windmill relight envelope
How many strategies are there for engine fail in the cruise?
3
Standard
Obstacle
Fixed speed
How do you determine which strategy to use?
Use the standard strategy, unless procedure has been established prior to dispatch
What happens if you press EO CLR?
It removes the engine out condition, and restores all engine operative predictions. It cannot be reversed
What is the engine failure in the cruise procedure?
PF setsall levers to MCT
Disconnect ATHR
Set appropriate heading and pull
Determine engine out recovery altitude
When ready for descent, PF sets speed and pulls
Set EO recovery altitude, and then pull for OPEN DES.
When appropriate, ECAM actions
Do not decelerate below green dot, hence at high levels descent needs to start quickly.
When V/S is less than 500fpm, pull V/S 500fpm and reengage A/THR.
Set long range cruise speed
With A/THR disconnected, how is speed controlled in OPEN DES?
Elevator
What exactly is EO REC MAX?
Long range cruise engine out maximum flight level with engine anti-ice off
Will cross bleed be available if there was an engine failure in the cruise?
Cross bleed available if no engine fire agent was discharged
Why is traffic a potential problem when drifting down?
ATC may not be aware what you’re doing yet
TCAS TA available only, and this may not have been set yet
What is important to mention to ATC during engine failure in the cruise?
Mayday
What approach capability is likely after engine fail? Why?
CAT3A
No electrical supply split
What should be done after checking the status page?
Review fuel, which will determine if there is a leak, and therefore help with the ‘diagnose’ stage.
Also worth remembering crew may have been at stations for a while
Where should PF hands be during the driftdown?
Hand on thrust lever to remember that A/THR is off
If using obstacle strategy, what should happen after being clear of obstacles?
Revert to standard strategy
What can crew look for if flameout without damage suspected?
Rapid decrease in EPR/N1, N2, EGT, FF.
What can crew look for if engine damage suspected?
The flight crew can suspect engine damage if two or more of the following are observed.
Rapid increase of EGT above red line
Important mismatch of rotor speeds, or absence of rotation
Significant increase in aircraft vibrations,
buffeting, or both
Hydraulic system loss
Repeated, non-controllable engine stalls
During driftdown, why might HYD not show as a secondary failure?
Sufficient HYD pressure from the failed engine can be generated with the engine windmilling at higher speeds
Y ENG 2 PUMP may also not appear as an inop system for the same reason
The warning will then appear as the aircraft slows down
If suffering from a FADEC fault, what considerations are there for the ECAM procedure?
FADEC cannot monitor certain attributes, such as thrust lever position, hence when carrying out the ECAM, THR LEVER 2 - IDLE wont disappear, and can be treated as a non-monitored line
Also, engine out case may not be detected, so HYD, BLEED and ELEC need to be checked too
(It may also not detect the engine out condition, and hence not give an EO REC MAX, so flysmart could be used)
