Today I was replaying the Electrics Sys of A320 CBT for the third time, but I didn't hear nothing about a secondary nature of this failure.
As you already know, Emer Elec Config. may be mainly caused either by a Dual Generator Failure or Dual AC Bus Fault ... so my question is:
- Which kind of other failure, if any, may bring the aircraft to Emerg Elec Conf. ?
Thanks in advance,
