Looking at the FCTM again. If the line:
The first officer carries out the ECAM actions until shutting down the
remaining engine(s).
was meant to be include shutting-down the engines, rather than stopping at that point, then how can the following paragraph include a consideration that involves taxying?
. The captain builds up his decision to evacuate depending on the
circumstances. Considerations should be given to:
-- Possible passenger evacuation of the aircraft on the runway.
-- Vacating the runway as soon as possible.
-- Communicating intentions or requests to ATC
I have now unearthed a 2005 CX FCTM which is heavily re-written from the Airbus original (in better English) and it says:
If the take-off has been rejected due to an engine fire, ECAM actions should be completed down to and including discharging the fire agents into the affected engine. If the fire remains out of control after having discharged the fire agents, the on ground EMERGENCY EVACUATION paper checklist should be actioned.
Which supports the idea that the remaining engines are shut-down in the Emergency Evacuation Checklist not the ECAM.
Personally, I cannot see why performing the shut-down as part of the Emer Evac checklist would cost any evacuation time. The engines would still be shut-down before the evac signal was triggered in the cabin.
