The term Inboard describes which portion of the aircraft?

• A. Outer most part of the aircraft. Closest seats to window
• B. Inner most part of the aircraft. Closest seats to aisle
• C. Front of the aircraft
• D. Tail area

Answer: (B)

Inboard means toward the center of the aircraft, toward the aisle. In the cabin, seats that are closest to the aisle are nearer the centerline than the window seats, so describing the inner-most part of the aircraft and the seats closest to the aisle correctly captures what inboard means. The front or tail describe longitudinal position along the fuselage, and window-adjacent seats are on the outer side (outboard), not inboard.
