Which doors on an aircraft are used by caterers and other support personnel to deliver services, sometimes labeled 1R or 2R?

• A. Service Doors
• B. Cargo Doors
• C. Crew Doors
• D. Passenger Doors

Answer: (A)

Service doors are the doors used by caterers and other support personnel to deliver services, and they’re often labeled 1R or 2R to indicate their location on the right side of the aircraft. This designation helps ground crews and cabin crews access the galley area directly without using passenger doors, making meal and supply delivery faster and less disruptive to travelers. It also keeps servicing separate from the main passenger entry and exit points, which helps with safety and organization. Cargo doors, by contrast, are in the cargo hold for freight; crew doors provide internal access for flight crew; passenger doors are the primary exits for passengers. So the doors used by caterers for service delivery are the service doors.
