Recovering form ELEC EMER CONFIG A330
Good afternoon to all:
Whilst reviewing the A330 ELEC EMER CONFIG scenario, I came across one of those doubts that gets ones ticker go mad!
The question is as follows:
If I happen to restore ALL generators, a specific ECAM pos-up. This leads me to reset FCMC 1+2......
Next, as usual, I will consider computer resets (if any) and expanded checklists (if time allows), following that the STATUS will be reviewed.
According to my FCOM:
ELEC EMER CONFIG (Cont'd)(GEN 1 OR/AND GEN 2 RECOVERED OR APU GEN AVAILABLE))
, for slat extension, LAND RECOVERY must be pressed (to recover AC and DC LAND RECOVERY busses, in order to power SFCC1 LGCIU1 etc etc...), and then the procedure goes on to.... FOR LANDING GEAR GRAVITY EXTENSION........ ????
Why is this last bit included in the STATUS??? If I have recovered the entire ELEC rig, including the land recovery busses, why would I want to extend the gear by gravity, hence loosing NWS?
As far as I understand, only one bus will be de-energized, even when LAND RECOVERY is pressed, this bus will be the AC ESS GND, however according to my FCOM, no part of the landing gear, brakes, nws etc... is powered by this bus....
Can anyone bring some light on this matter?
Many thanks,
Alberto
