What steps are involved in arming/disarming cabin doors for takeoff and landing?

• A. Arm the door first, then verify area is clear, and confirm indicators.
• B. Ensure the door status is correct, verify area is clear, then arm/disarm as required and confirm indicators show the correct status.
• C. Disarm doors only when instructed by the captain.
• D. Leave the door armed throughout flight.

Answer: (B)

The main idea here is to configure the door safely for the flight phase by confirming its status, ensuring the area is clear, setting the door to the required mode, and then checking the indicators. You verify the door’s current setting first so you know what you’re about to change. Then you make sure the area around the exit is clear of people and obstructions, because arming or disarming affects whether a slide will deploy and could cause harm if someone is in the way. After that, you arm or disarm as required for takeoff or landing, ensuring the door will operate correctly in an evacuation if needed. Finally, you check the indicators to make sure the door shows the correct status. This final confirmation is essential because it proves the door is in the intended configuration. Leaving a door armed during flight or disarming without completing the status and area checks can lead to unsafe deployment or improper configuration.
