Actually you have a 30 second latching of ELAC 2 to Battery 2 (standby mode).
****CAVEAT - Im not entirely sure what functions you get in this 'standby mode'****
That's discussed in the AMM, and is only briefly mentioned in the FCOM. After 30 seconds the latching is removed, and as a result if for some reason the RAT GEN doesnt come on line then you have nothing, but during 8 seconds of deployment you still have ELAC 2, albeit for only 30 seconds.
Thats what i can see so far.
I still havent found out what happens to the Ailerons if you lose ELAC 1 and the Green system. The pages from the AMM which i have dont mention that configuration anywhere...im still researching it though.
