ermmm,
Fortunately we in the military (British at any rate) don't have worry about electric jets.
Actually, following major electrical failures the RH screens of the 'J' would go dark (along with both the HUDs). Standby instruments are on the LHS only if all power was lost. Have to be pretty dire though! Daresay C-17 and the new Nimrod will be similar.
The only bit that concerns me however is the thought of x-wind landings when I can't get to that wheel....
