OK...First things first, If a planes main wings were sawed off, how many pneumatic, hydraulic and electrical connections might there be on an old jetliner that would have to be plugged or capped, on each side, in order for the ships systems to come back on-line...specifically pneumatic and electrical. For the moment, I don't beleive hydro will be necessary for the time being.
Second, Since FAA regs would not apply, could standard "8d" HD Motor Vehicle Batteries be rigged to provide the 28V necessary to power up the aircraft.
Third, Any ideas on how to rig a makeshift fuel system when the tanks are no longer an option.

Quoting United727 (Thread starter): Since FAA regs would not apply, could standard "8d" HD Motor Vehicle Batteries be rigged to provide the 28V necessary to power up the aircraft.
Just some general thoughts.
Since you're not worried about regs I'd say 28V is 28V. But batteries can't power an airplane for very long, and you could only power up a very limited number of systems due to limited capacity. So I guess it depends what bits exactly you are powering and what kind of timescale you are looking at. Unless you had a shedload of batteries of course.
There's also the issue that some buses may not be powerable by batteries at all, for example generator buses.
I think some sort of portable generator would be a better option. Or start up an engine and use that generator. Is this the plan? If you're down to batteries in a plane it's pretty much "shed as much load as possible and land ASAP" (unless you're in a glider).
