A 747 has no rat. Do windmilling engines provide as much electricity as working ones? Can the flaps be driven solely by windmilling engine electricity?
No electricity below idle, so none from a windmilling engine. Normal flaps are run by hydraulics and air. Trailing edge flaps will run on hydraulics from windmilling engines. If all 4 engines are dead, no leading edge flaps.
