AMAD stands for?

• A. Automotive Mounted Accessory Device
• B. Aircraft Mounted Accessory Drive
• C. Airframe Mounted Accessory Drive
• D. Airframe Main Accessory Drive

Answer: (C)

AMAD stands for Airframe Mounted Accessory Drive. This is the drive assembly attached to the aircraft’s airframe that provides power to the engine’s accessories—such as generators and hydraulic pumps—via the engine’s accessory drive system. The key idea is that the drive is mounted to the airframe (not the engine) and drives the accessory gear train when the engine is running or during starting operations. The other phrasings are not the standard terminology: automotive-mounted implies a ground vehicle context, while aircraft-mounted is not the precise term used in manuals; airframe main accessory drive suggests a different designation and isn’t how the system is named.
