Airbus Dual Eng Fail procedure question

ELAC 2 standby supply on HOT2?

Hi guys!

One thing, I do not quite understand about the whole issue is why ELAC 2 is unservicable in Elec Emer Config?

Checking the bus equipment list, gives DC ESS for ELAC1 and DC2 for ELAC2 in normal circumstances. I can understand that if this was the only supply, ELAC 2 would be U/S with a Dual Eng Fail, as DC2 is gone.

However, the bus equipment list also gives HOT1 for ELAC1 and HOT2 for ELAC2 as "standby supply". The HOT busses are directly connected to the batteries, so they are always powered until your batteries are flat.

Shouldn't the ELAC2 continue living of the HOT2 bus for the remainder of the flight (and control the RH aileron via the blue Hyd), even with the aircraft in Elec Emer Config? What am I missing here?

Thanks for your help,

Torsten
