also, on on airplane, the only things that are "always on" are things on battery. everything else draws power from the airplanes generator (which is powered by the engines), so you can cut the flow of electricity through the breaker panels to basically everything, cause you can't work on fixing a system with the power on, and you can't have something going haywire that you can't shut off.

anyways, very few things are on battery, the blackbox stuff, the gps (to hold almanac info while the plane is off) and a couple other things.
