If ELAC 1 (and by extension the blue hydraulics) responsible for the left aileron fails, then ELAC 2 would end up controlling the right aileron using the blue hydraulic jack. Correct?
If that's the case then how is this possible? Since the blue hydraulics already failed when ELAC 1 failed. Or do the blue hydraulics for both the left and right aileron act independently of each other?
The right aileron is normally controlled by ELAC 1 using only the Green jack, so if Blue Hyd and ELAC 1 failed, you would be left with left aileron only, controlled by ELAC 2 using the Green jack. (You would also have most of your roll spoilers)
Yes, all the controls work independently, to give redundancy. Certain hydraulic and FBW failure combinations will leave you with a single aileron or elevator.
