What does the ADG power?

• A. ADG bus
• B. HEFAS
• C. Hydraulic pump 3B
• D. Essential AC bus

Answer: (A)

When normal power sources are unavailable, the Air Driven Generator provides emergency electrical power by feeding a dedicated ADG bus. This bus is the immediate distribution point for the ADG’s output, delivering power to essential equipment to keep critical systems running. The ADG is not primarily dedicated to powering hydraulic components like hydraulic pump or flight-control hydraulics (HEFAS), nor is the question about the bus that the ADG can influence in all configurations; the direct connection from the ADG is to the ADG bus, which then supplies the essential loads.
