Camber affects the airflow velocity around the wing. Which statement is true?

• A. The airflow above travels faster than below.
• B. The airflow below travels faster than above.
• C. The airflow above travels faster than below.
• D. There is no velocity difference

Answer: (C)

Camber changes how air must flow around the wing, making the top surface accelerate more than the bottom. With a cambered profile, air sweeping over the top follows a longer, curved path and speeds up to stay attached. That increased speed reduces pressure on the upper surface (Bernoulli’s principle), while the bottom stays comparatively slower with higher pressure. The resulting pressure difference generates lift. So the statement that the airflow above travels faster than below is true. The other ideas—bottom flow faster, no velocity difference—don’t match how a cambered wing creates lift, since a velocity difference is essential for the lift produced by camber.
