The fault list reads like a printout of the DDG!
Given that synoptic display, I think I would be erring on the side of getting it on the ground ASAP as at the back of my mind would be the possibility of battery power only, which doesn’t give you that long before you’re in a cockpit with no instrumentation at night. I can’t find it in the manuals but I think the backup batteries in the flight controls are only guaranteed for 20mins...
There isn’t a MAIN BATTERY DISCH advisory in that list so maybe power was getting through to the battery charger, although I wouldn’t like to depend on it! Top marks to the guys for a rapid and successful diversion.
