I see the flying controls have 3 hydraulic systems, with the centre electrically powered, so with a double engine failure it is essential to start the APU, (from the battery)?

My original post was just to high light how Boeing are in a pickle by doing away with engine bleed. Though a bit old fashioned, engine bleed was reliable power source. Without bleed we need huge power source from generators and batteries etc, and has actually created a problem on basic electric systems which normally do not have any serious problem on most aircraft these days.
