Which term is the component designed to create lift, such as a wing?

• A. Aero
• B. Air
• C. Airfoil
• D. Altitude

Answer: (C)

Lift comes from an airfoil, the cross-sectional shape of a wing designed to generate lift as air moves past it. The airfoil typically has a curved upper surface and a flatter lower surface, which makes air flow faster over the top and slower underneath. This speed difference creates lower pressure on top and higher pressure beneath, producing an upward force that lifts the wing. The wing is made up of many airfoil sections along its span, all contributing to overall lift. The other terms don’t name a lift-producing surface: aero is just a prefix related to air, air is the gas itself, and altitude is a height measurement.
