Which component is primarily used to generate lift for the wings?

• A. Slats
• B. Flaps
• C. Wing
• D. Spoiler

Answer: (C)

Lift comes from the wing itself—the primary lifting surface. Its airfoil shape, when swept through the air, causes air to move faster over the top than beneath, creating a lower pressure above and a higher pressure below. That pressure difference pushes the wing upward. Movable surfaces like slats and flaps increase lift at lower speeds by boosting camber or wing area, but they’re used to augment lift rather than generate it. Spoilers reduce lift by disturbing the airflow, mainly for descent or braking. So the wing is the main source of lift.
