Which wing component often houses fuel tanks?

• A. Fuel Tank
• B. Wing Tip
• C. Wing Flap
• D. Spar

Answer: (A)

Fuel is typically stored in tanks built into the wings. The wing structure provides hollow spaces between the main load-bearing elements, such as the spars and ribs, where these tanks are placed. Locating fuel in the wings keeps the weight near the aircraft’s center of gravity, so as fuel is burned, balance and handling remain more stable. It also makes efficient use of space and minimizes aerodynamic disruption.

Wing tip tanks exist on some designs but are not the standard arrangement for most airplanes. Wing flaps are movable control surfaces, not storage. The spar is a primary structural member, not a fuel container.
