What powers the AMAD accessories?

Explanation:
AMAD stands for Airframe Mounted Accessory Drive, the gearbox that powers the aircraft’s accessories. When the engine is running, it drives the AMAD, providing power to the generators, hydraulic pumps, and other attached systems. On the ground, during maintenance mode, the APU takes over to drive the AMAD so those same accessories can operate without the main engine. Batteries, external power, or solar power don’t drive the AMAD, so the engine in normal operation and the APU in ground maintenance mode are the correct sources.
