If a door shows an abnormal alarm during flight, what is the correct action?

• A. Do not override; alert the Captain and follow the abnormal door procedure in the SOP.
• B. Try to override.
• C. Deactivate door.
• D. Evacuate immediately.

Answer: (A)

Abnormal door alarms require strict adherence to established procedures and strong crew coordination. Do not override or disable the door system—the alarm is a safety signal that must be verified and managed per the SOP. The correct action is to alert the Captain and follow the abnormal door procedure, because this sequence ensures the Captain has full situational awareness, the door’s status is properly assessed, and appropriate contingencies are prepared. The Captain will determine whether to continue, divert, or take other steps based on the verified information. Alternatives like attempting to override, deactivating the door, or evacuating immediately bypass safety checks or rush decisions, which can create unsafe conditions or unnecessary disruption.
