I should have framed the question this way:
How far would either aircraft fly if there is trouble in the E&E bay
that compromises the electrical system and you are down to DC
power...And then you lose even that?

Isn't that like saying "what would happen if the bloody wings
were to fall off"?...pretty silly statement imo.

I can't understand the obsession with DC power either. Airplanes
mostly
use
AC power for controls. I have yet to see a synchro that runs on DC.

Almost all a/c generate A.C. power then transform and rectify
some of it to DC with TRU's so the only emergency supply of DC is
a very short lived set of batteries mostly used for emergency
flight instruments and other very essential services.

I believe the 767 has 2 DC generators on the engines.

No, it does not. An AC gen on each engine and the APU.
The eng gens are referred to as an IDG. (integrated drive
generator) The constant speed transmission and gen are
in one 'package.'

In 26 years
of flying (13,000 hours) I've never lost all A.C. power on any
a/c (nor heard of any of my friends doing it either) so it's not
one of those 'ho hum' occurrences.

No gyros could get ugly fast.

I have to wonder at the posters assertion that there is a fault problem
with
the 767 E&E bay. It is well known in industry that it rains in the
A-330/340 E&E bay and I doubt USAF would see that as a selling point.
