Which door is primarily used for passenger boarding and deplaning?

• A. Main Cabin Door
• B. Overwing Exit
• C. Crew Entrance Door
• D. Tail Cone Door

Answer: (A)

Passengers board and deplane through the door designed as the main boarding point. This door is located at the front of the cabin, sized for full passenger flow, and connects to a jet bridge or air stairs for normal operations. Other doors have specialized roles: overwing exits are primarily emergency exits for evacuations and aren’t used for regular boarding; the crew entrance door is for crew access to the cabin; and the tail cone door is not a passenger entry point. So the main cabin door is the door used for everyday boarding and deplaning.
