Question of the day

On the MAX, which statement about the APU DOOR light when the APU has been shut down is true?

Explanation:
After shutdown, the APU exhaust door is left open to vent residual heat and allow cooling. The APU DOOR light indicates the door’s status, so it remains lit to show that the door is open during this cooldown period. The APU is no longer running, and the door status isn’t unknown—it's a defined state. Once cooling completes, the door will close automatically.
