Well having worked on a variety of Boeing/Airbus a/c I have never heard of a PEPDC?
DC is normally supplied by a DC BATT bus or the DC buses are through TRU's.
So how do you control DC? For example, you have to charge the batteries. The batteries have to send a signal somewhere to get connected with DC1 and/or DC2! How are the BCL controlled?
@Amadis of Gaul: Are you an airline pilot? Just wanted to know!
