Which component generates lift?

Which component generates lift?

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

Answer: (D)

Lift is produced by the wing, the aircraft’s main lifting surface. Its airfoil shape and the angle at which it meets the airstream cause air to move faster over the top than under the bottom, creating lower pressure above and higher pressure below. That pressure difference pushes the wing upward, generating lift for the whole airplane. Slats and flaps modify how much lift the wing can produce at different speeds by changing camber and surface area, which is especially useful for takeoff and landing. Spoilers reduce lift by disturbing airflow when you want to descend or brake after landing. So the wing itself is what generates lift.
