What does the door status page confirm?

• A. Doors are closed and locked
• B. Doors are open and unlocked
• C. The interphone is operating
• D. The oxygen system is normal

Answer: (A)

The door status page is a readiness display that must confirm every cabin/exit door is fully secured before flight operations. It specifically indicates that doors are closed and locked, which is essential for safe cabin pressurization, proper door seals, and evacuation readiness. If a door were not closed or not locked, the page would not show all clear, and the crew would not be cleared to proceed. This readout is distinct from other systems like interphone status or oxygen system status, which have their own pages and checks. So the best answer is that the page confirms all doors are closed and locked.
