Which statement best describes door status indicators during operations?

• A. Indicators are not important.
• B. Confirm indicators reflect armed or disarmed status as required for takeoff or landing.
• C. Indicators can be ignored if the crew is confident.
• D. Indicator status is only checked by maintenance after flight.

Answer: (B)

Door status indicators show whether an emergency exit is armed or disarmed, and this status must align with the phase of flight. During takeoff and landing, it is essential that exits used for evacuation are armed so that, if an emergency occurs, opening the door will trigger the slide to deploy automatically. The indicators provide a quick, unambiguous confirmation that the door is in the correct state, allowing the crew to proceed with the safety check and not rely on memory or assumption. If the status isn’t correct, evacuation could be delayed or a slide could deploy or fail to deploy when needed. Therefore, the crew verifies the indicator readings and, if necessary, adjusts and rechecks to ensure a safe, ready-to-evacuate exit path.
