In a standard turn, which part describes the greater arc?

• A. Aileron
• B. Wing
• C. Fuselage
• D. Tailplane

Answer: (B)

In a standard turn the aircraft follows a circular path around a vertical axis, so the parts of the airplane that are farther from the turn’s center describe larger circles. The wings extend widest from the centerline, making the wing tips—the farthest points from the center—the ones tracing the largest arc. The fuselage and tailplane stay closer to the center and thus describe smaller arcs. The aileron is just a movable surface on the wing, not the feature that determines the arc size. So the wing is the part that describes the greater arc.
