Which door is not displayed on the DOORS synoptic page?

• A. Crew Escape Hatch
• B. Main Cabin Door
• C. Service Door
• D. Cockpit Door

Answer: (A)

The DOORS synoptic page is meant to show the status of the doors that are part of normal operations and evacuation flows—primarily the main cabin door, the service door, and the cockpit door. These doors have standardized sensors and indicators that feed the synoptic display so crew can quickly see if a door is closed, armed, or faulted, which is crucial for safe boarding, galley access, and cockpit security.

The Crew Escape Hatch, while an important emergency escape route, isn’t part of that regular door monitoring network. It’s a dedicated emergency feature with its own procedures and status checks, and its condition isn’t displayed on the standard DOORS synoptic page. That’s why it doesn’t appear there, whereas the other doors do.
