If a door warning indicator persists after you have verified all doors are closed and locked, what is the recommended procedure?

• A. Hold or abort the flight following the checklist.
• B. Continue taxi and takeoff.
• C. Deactivate the warning light and proceed.
• D. Notify passengers to evac immediately.

Answer: (A)

A door warning that stays on after you’ve confirmed all doors are closed and locked means you cannot continue toward takeoff. This is a safety-critical indication: either a door isn’t fully latched, the latch has a fault, or the warning system itself is faulty. The proper procedure is to hold the aircraft and follow the non-normal/ checklist procedures, which typically means delaying or aborting the takeoff until maintenance can inspect and clear the issue. Do not proceed taxiing or takeoff, do not deactivate the warning, and evacuating passengers is not appropriate unless there is an actual emergency. Following the checklist ensures you don’t risk a door opening in flight and keeps everyone safe.
