Where does power to AMAD accessories come from during normal operation?

Explanation:
Power to the AMAD accessories comes from a mechanical drive, not from a battery or hydraulic pressure. In normal operation the AMAD is driven by the engine through the engine’s accessory gearbox, which spins the AMAD to run its generators and hydraulic pump. When the aircraft is on the ground and the engines aren’t turning, the APU can be started to drive the AMAD for maintenance or ground power. External power carts provide electrical power to the aircraft but do not spin the AMAD, and the hydraulic system isn’t the source of the AMAD’s drive.
