ELAC 2 No Dispatch A320
The Dispatch Deviation Guide for my company lists ELAC 2 as a no go item. ELAC 2 is suplied by the DC2 Bus and ELAC 1 and SEC 1 are powered by the DC ESS bus for operation in the EEC. All three have a standby power supply as either HOT 1 or HOT 2 so presumably all have a separate standby supply regardless of whether the AC network is supplied. I am led to believe by inference only that ELAC 2 is a no go because the flight controls need some power if the aircraft transitions to the EEC but if all three are powered by a Hot bus, I can't understand why ELAC 2 would be the no go and it's acceptable to dispatch without ELAC 1. I'm missing something I know but unfortunately the FCOM doesn't deal with it in sufficient detail. Can anyone provide me with the reason? I'm assuming that the my company's DDG is a straight transcript of the Airbus MMEL in this regard.
