Which indicators signal that the jet bridge is correctly aligned with the aircraft door?

• A. All of the above
• B. Visual alignment marks
• C. Door-to-bridge gap within tolerance
• D. Crew confirmation of door status before deplaning

Answer: (A)

The key idea is that safe boarding requires confirming the jet bridge is in exact, secure position relative to the aircraft door using multiple checks. Visual alignment marks give an immediate, visible cue that the bridge lines up with the door. The door-to-bridge gap within tolerance verifies the physical distance is appropriate—neither too far nor too close—ensuring the bridge can form a proper seal and that passengers won’t encounter a gap or collision. Crew confirmation of the door status before deplaning adds a final safety layer, confirming the door is closed and latched (and any interlocks are set) so it’s safe to begin passenger flow. Together, these checks cover different risk aspects and provide complete assurance that the door-bridge interface is ready for boarding.
