Which statement best describes a wide-body aircraft?

• A. A single-aisle configuration
• B. A two-aisle configuration
• C. A three engines configuration
• D. A small fuselage

Answer: (B)

Wide-body aircraft are designed with a larger fuselage diameter that can accommodate two passenger aisles side by side, allowing more seats and greater comfort on long flights. The two-aisle cabin layout is the defining feature that sets wide-bodies apart from narrow-bodies, which use a single central aisle. A single-aisle configuration describes narrow-body planes, not wide-bodies. Engine count isn’t what defines a wide-body—you can have wide-bodies with two engines (like many common models) or four-Engine wide-bodies in the past, but that’s not the defining trait. A small fuselage would imply a narrow-body, not a wide-body. Therefore, the best description is a two-aisle configuration.
