Parasite drag is defined as?

Parasite drag is defined as?

• A. Drag from components that don't create lift (Wheels, Fuselage)
• B. Drag from the body of the aircraft traveling through air
• C. Skin friction drag
• D. Induced drag from lift

Answer: (A)

Parasite drag is the drag produced by parts of the aircraft that do not contribute to lifting the aircraft. This includes the wheels, fuselage, antennas, and other non-lifting components, as well as form drag, skin friction drag on the surfaces, and interference where parts meet. The option describing drag from components that don’t create lift captures this definition most clearly, because it focuses on the source being non-lifting parts. Skin friction drag is actually a type of parasite drag, while induced drag comes from the generation of lift on the wings and is a separate effect. A vague statement like drag from the body traveling through air is less precise than identifying non-lifting components.
