Which statement describes the three basic wing placements found on aircraft?

• A. High-wing, mid-wing, and low-wing
• B. Vertical-tail, horizontal-tail, and delta
• C. Canard, swept, and straight
• D. None of the above

Answer: (A)

The concept here is where the wing is mounted on the fuselage. There are three basic placements: high-wing, mid-wing, and low-wing. A high-wing configuration places the wing on top of the fuselage, which provides good ground clearance for landing gear and engines and can simplify passenger access from the bottom of the fuselage. A mid-wing arrangement runs the wing roughly through the middle of the fuselage, offering very clean aerodynamics and efficient lift, but it’s more complex to design and maintain because the wing intersects the fuselage there. A low-wing setup attaches the wing near the bottom of the fuselage, which typically gives excellent downward visibility and easier integration of landing gear and fuel systems, though it reduces ground clearance.

Other options describe different aspects like tail configurations (which are not about wing placement) or wing shapes (planforms) rather than where the wing sits on the aircraft.
