In All Call, what factor determines the movement sequence?

• A. Door number order from front to back
• B. Floor level
• C. Passenger last names
• D. Seating row order

Answer: (A)

All Call guides people to move by the physical entry points on the aircraft, so the sequence is set by door numbering from front to back. This ordering keeps the aisle from bottlenecking, allows crew to manage boarding and setup efficiently, and reduces cross-traffic as passengers proceed to their assigned doors. The other factors—floor level, passenger last names, or seating row order—don’t determine how movement is staged because they don’t correspond to how passengers enter the plane or how the flow is controlled. So the front-to-back door order is the mechanism that establishes the movement sequence.
