Pull the ADG deployment handle even if it auto-deploys because...?

• A. It will allow the BATT buses to power the DC essential bus after touchdown
• B. It will fully retract the ADG
• C. It will deactivate the GPU
• D. It will reset the BATT Buses

Answer: (A)

The key idea is emergency electrical power routing. The Air Driven Generator provides a backup source of power for the DC essential bus when main generators aren’t available. Even if the system auto-deploys, pulling the ADG deployment handle ensures a solid electrical path that connects the BATT buses to the DC essential bus, so after touchdown the essential loads stay powered as the aircraft transitions to ground power or other power sources become available. In short, manual deployment guarantees the battery buses can feed the DC essential bus, which is critical during the post-landing phase. The other options don’t describe what this action does: it isn’t about retracting the ADG, deactivating the GPU, or resetting the battery buses.
