Unlikely, I know, but what happens if the A320 drops into the emergency electrical configuration when the blue hydraulic system is lost (through fluid loss)?
I assume the RAT will still deploy but not do anything (so RAT & EMER GEN FAULT light comes on), and the aircraft is running on battery power only, with all the unpleasant consequences that this entails.
Nothing in the FCOM about this short of a red "LAND ASAP", which is kinda obvious.
