ADG deployment may not occur if the aircraft wasn't the last power source (for example, when connected to a GPU). What is true regarding this behavior?

• A. It won't deploy
• B. It will always deploy
• C. It might deploy later
• D. It requires manual intervention

Answer: (A)

ADG deployment is tied to the status of the aircraft’s power sources. It’s designed to auto-deploy only when the electrical system loses all primary sources and there’s no external power supplying the aircraft. If you’re connected to a GPU, external power is still available, so the condition that would trigger automatic deployment isn’t met. In that situation, the ADG remains stowed and does not automatically deploy. That’s why the statement “it won’t deploy” is the correct one. It isn’t guaranteed to deploy if external power is present, and it isn’t something that would require manual intervention under normal automatic-deploy behavior.
