Form drag is defined as?

• A. Drag from components that do not create lift
• B. Drag resulting from the body of the aircraft traveling through air.
• C. Skin friction drag
• D. Induced drag from lift

Answer: (B)

Form drag is the pressure-based resistance that arises from the aircraft’s shape as it moves through air. The air must be pushed aside and flow wraps around the body, causing differences in pressure that create a rearward force. This pressure-drag component, tied to the vehicle’s form and frontal area, is a key part of parasite drag. It’s distinct from skin friction drag, which comes from viscous shear along surfaces, and from induced drag, which is generated by lift. So the drag produced by the body’s geometry moving through air best describes form drag.
