What type of wing contains all fuel?

• A. Wet Wing
• B. Dry Wing
• C. Semi-Wet Wing
• D. Floating Wing

Answer: (A)

The concept here is where fuel is stored in the aircraft. A wet wing means the wing itself forms the fuel tank, with internal cavities sealed to hold all the fuel. This design uses the wing structure—its ribs, spars, and skins—as part of the fuel storage, making efficient use of space and simplifying the airframe by avoiding separate fuel cells in the fuselage. A dry wing, by contrast, has no fuel stored in the wing; fuel is kept in tanks elsewhere, such as in the fuselage. A semi-wet wing implies only part of the wing contains fuel tanks, not the entire wing volume. Floating wing isn’t a standard term for fuel storage and doesn’t describe wing-mounted fuel tanks.
