Then, PF will
? Require the ECAM actions
At high flight levels close to limiting weights, crew actions should not be delayed, as speed will decay quickly requiring prompt crew response. The crew will avoid decelerating below green dot.
ABNORMAL OPERATIONS
OPERATING TECHNIQUES
Engine failure during cruise flow pattern
The A/THR is disconnected to avoid any engine thrust reduction when selecting speed according
to strategy or when pulling for OPEN DES to initiate the descent. With the A/THR disconnected, the target speed is controlled by the elevator when in OPEN DES.
Carrying out the ECAM actions should not be hurried, as it is important to complete the drill correctly. Generally, there will be sufficient time to cross check all actions.
STANDARD STRATEGY
Set speed target M 0.82/300 kt. The speed of M 0.82/300 kt is chosen to ensure the aircraft is within the stabilised windmill engine relight in-flight envelope.
The REC MAX EO Cruise altitude, which equates to LRC with anti-icing off, is displayed on the MCDU PROG page and should be set on the FCU. (Cruise altitude and speed are also available in the QRH in case of double FM failure).
If V/S becomes less than 500 ft/min, select V/S - 500 ft/min and A/THR on. This is likely to occur as level off altitude is approached.
Once established at level off altitude, long-range cruise performance with one engine out may be extracted from QRH or Refer to FCOM/PER-CRZ-OEI-GEN-10 PROCEDURE.
OBSTACLE STRATEGY
To maintain the highest possible level due to terrain, the drift down procedure must be adopted. The speed target in this case is green dot. The procedure is similar to the standard strategy, but as the speed target is now green dot, the rate and angle of descent will be lower.
The MCDU PERF CRZ page in EO condition will display the drift down ceiling, assuming green dot speed and should be set on FCU. (One engine out gross ceiling at green dot speed is also available in the QRH and FCOM).
If, having reached the drift down ceiling altitude, obstacle problems remain, the drift down procedure must be maintained so as to fly an ascending cruise profile.
When clear of obstacles, set LRC ceiling on FCU, return to LRC speed and engage A/THR.
ONE ENGINE-OUT LANDING
Applicable to: ALL
Autoland is available with one engine inoperative, and maximum use of the AP should be made to minimise crew workload. If required, a manual approach and landing with one engine inoperative is conventional. The pilot should trim to keep the slip indication centred. It remains yellow as long as the thrust on the remaining engine(s) is below a certain value. With flap selected and above this threshold value, the indicator becomes the blue beta target. This is a visual cue that the aircraft is approaching its maximum thrust capability.
Do not select the gear down too early, as large amounts of power will be required to maintain level flight at high weights and/or high altitude airports.
