Before arming the doors at the boarding door, what must you assess for FIRST?

• A. Cabin is secure
• B. Jetbridge movement
• C. Visual cross-check
• D. Bags are stored

Answer: (B)

The first thing to verify is that the jetbridge is stationary and properly positioned. Why this matters is that arming the doors activates the door and slide systems, so any movement or misalignment of external ground equipment right at the doorway creates an immediate safety risk—there could be a collision with the jetbridge, injury to staff, or the slide deploying into an obstacle. Once you confirm the jetbridge is secure and not moving, you can proceed with the other checks (such as ensuring the cabin is secure and the area near the door is clear, with bags stored), but the initial priority is external equipment status to prevent a dangerous interaction during door operation.
