Which term means the shape of the wings?

• A. Wings
• B. Airfoil
• C. Slats
• D. Flaps

Answer: (B)

Airfoil is the term for the shape of a wing’s cross-section. This shape—typically a curved upper surface with a flatter lower surface—controls how air flows as the wing moves through the air. The fast-moving air over the top reduces pressure on that surface, while the air beneath pushes upward, creating lift. That specific cross-sectional form is what engineers mean by the airfoil. Wings refer to the whole wing structure, not just its shape. Slats are movable pieces on the leading edge that can extend to improve low-speed lift, and flaps are hinged sections on the trailing edge that increase lift and camber during takeoff or landing.
