LGCIU 1+2 fault & abnormal LG landing
Is it wise to use Abnormal LG landing QRH procedure after double LGCIU failure (LGCIU 1 is not electrically connected, so no indication)? If it is reasonable:
1. Is it wise to fly low pass?
2. How do we have to fullfill some sections of this procedure with IF conditions (and no condition for unknown LG position at all).

I personally would do as much of the abnormal landing gear checklist as practical. As to doing a low fly-by seems pretty pointless to me since they can only really advise you that the gear APPEARS down & also when were we last trained to fly down a r/w level at 100'?

TyroPicard I guess they could use them as long as it's during the day or good vis. Also Airbuses do not have any visual downlock indications visible from inside or outside the a/c. So I still do not see the point of doing a low pass over the r/w.

If one LGCIU fails the other LGCIU takes over control, and a diminished gear/door indication is shown on the SD page, if the remaining LGCIU fails you will still have gear down indication via a hard wired circuit inside LGCIU in the #1 position., even if the LGCIU 1 is failed. This indication circuit is still powered to provide the 3 gear indication triangles adjacent the gear lever.
LGCIU 1 is not electrically connected?
Do you mean not fitted to the rack..
In my fleet LGCIU #1 must be operating, ..The only MEL/DDG relief is for LGCIU 2.
As far as fly past to check gear down, ??????

Bolty,
sorry - I did not mentioned my type - it is Airbus, but 320.
So gears are not hard wired to indication and we have only two LGCIUs. Yes, in some failures it could be indications, but not for sure. I take the worst situation and wonder.
Thanks for responses
