Select THR MCT when the LVR MCT message flashes on the FCU, triggered as the speed index reaches Green Dot and resume the climb using MCT. If the thrust levers are already in the FLX/MCT detent, move them to CL and then back to MCT to engage the A/THR. After MCT is set, both packs are selected on by the PNF (if previously off for take-off).

FCTM Operating Techniques
When an engine failure occurs after take-off, noise abatement procedures no longer apply. The acceleration altitude provides a compromise between obstacle clearance and engine thrust limiting time. It allows the aircraft to be configured to Flap 0 and Green Dot speed. This provides the best climb gradient.
Once established on the final take-off flight path, continue the ECAM until the STATUS is displayed. At this point, carry out the AFTER T/O checklist. Finally, review the STATUS and consult the OEB for applicability.

ENGINE FAILURE DURING INITIAL CLIMB-OUT
Proceed as above. If the failure occurs above V2 however, the SRS will command an attitude to maintain the speed at which the failure occurred. In any event the minimum speed is V2.
When an engine failure is detected, the FMGS predictions are based on the engine-out configuration and any pre-selected speeds entered in the MCDU are deleted. Consider the use of the EOSID, if one exists in the database.
ENGINE FAILURE DURING CRUISE
There are three strategies available for dealing with an engine failure in the cruise:
.  
Standard strategy

.  
Obstacle strategy

.  
Fixed speed strategy


Unless a specific procedure has been established before dispatch (considering ETOPS or mountainous areas), the standard strategy is recommended.
As soon as an engine failure is recognised, the PF should call for the ECAM actions and simultaneously:
.  
Set MCT on the remaining engine(s).

.  
Disconnect the A/THR.

.  
Select the SPEED according to the strategy.

.  
Select a HDG to keep clear of the airway, preferably heading towards an alternate, if appropriate. Consider the aircraft position relative to any relevant critical or equi-time point.

.  
Select the LRC ceiling or driftdown ceiling according to strategy in the FCU ALT window and pull for OP DES when target speed is reached.


Placing the thrust lever(s) to MCT and carrying out the ECAM actions should not be rushed, as it is important to complete the procedure correctly. Generally, there is sufficient time to cross-check all actions. However, at high levels close to limiting weights, more urgency is required, as speed decays more quickly.
The FCU selections for an engine failure run from left to right:
.  
SPD select.

.  
HDG select.

.  
FCU altitude insert.

.  
ALT selector pull (when target speed is reached).


8.20.10

A330/A340 Non-normal Operations REV 1 (6 JUN 05)
FCTM Operating Techniques
Standard Strategy (Long Range Strategy)
Set .82M/300 kt. The speed of .82M/300 kt is chosen to ensure the aircraft is within the stabilised windmill engine relight in-flight envelope. The thrust is fixed at MCT with A/THR disconnected and speed is controlled by the elevator. The REC MAX EO cruise level displayed on the EO PROG page, equates to LRC with anti-icing off. The nearest semi-circular or RVSM cruise level at or below this level should be set on the FCU. Once established in the descent, the PERF CRZ page shows time to descend and predicted descent distance. These can also be checked on the relevant performance table in the QRH. If V/S becomes less than 500 ft/min, select V/S .500 ft/min and A/THR on. This is likely to occur approaching level off altitude, or at light weight.
