From what I can read on the 'net the aft EE bay is the main Electrical distributor point as the 4 main starter/generators and 2 apu generators feed in there.
IF the above picture shows the RAT in it's production location then worryingly
does it point to the emergency power distribution system being located in the aft EE bay as well.........all the eggs in one basket?
Airbus have a philosophy of physical separation of primary/secondary and emergency power supply systems with, naturally, a weight penalty.
