05 - TRAINEES’ ACTIONS (END)
OVERVIEW
The FMGS PROG page will show the EO MAX REC altitude. In the QRH there are tables containing details of engine out ceiling, time to descend, distance taken and fuel used. There is also a graph to calculate gross ceiling. Tables are available for long range cruise performance, an in-flight check of fuel consumed and time to destination. The decision on which technique is appropriate should be taken during the aircraft deceleration following the failure.
Once established in the descent, the relevant table can be entered, and the information assimilated.
If V/S becomes less than 500 fpm during any of the descent profiles, select V/S mode and maintain a minimum of 500 fpm. This is likely to happen as level off altitude is approached.
The ECAM actions and placing the thrust lever to MCT should not be hurried, as it is important to complete the drill correctly, not in the shortest possible time. Generally, there is sufficient time to check all actions before rushing into them. However at high flight levels close to limiting weights, if an engine fails speed will decay very quickly requiring prompt crew response.
In congested airspace, be aware that a low rate of descent may be unacceptable to ATC, and be prepared to adjust accordingly.
Single engine operations will typically use 15% more fuel than with both engines, which may become a factor if a long diversion is contemplated.

04 - INSTRUCTOR’S ACTIONS
Briefing of the following key points.
MAIN
.
Factors influencing decision to attempt relight.
.
Engine relight in flight procedure (windmilling and starter assisted).
.
Relight envelope and limitations (loss of protections).
.
Task sharing and actions requiring crew confirmation.
SECONDARY
.
Systems to restore or engine shut down procedure.
05 - TRAINEES’ ACTIONS
Before attempting a relight in flight, gather all relevant information to decide whether a relight should be attempted. Consider engine damage, icing or volcanic ash encounter and their effects on a successful relight. Check for satisfactory indications of N1, N2 and oil quantity. Further, is there an appropriate time to relight, when workload is low ?
Refer to QRH 2.15 for ENG RELIGHT (in flight) drill. Auto start is recommended as FADEC will determine whether an assisted start or a windmilling start is appropriate. The crew must be ready to take appropriate action in case of abnormal start as no start protections are provided in flight. The stopwatch should be used to monitor light up after fuel flow increase.
