The auxiliary fuel tanks are installed in which wing area?

• A. Wing center section
• B. Wing root
• C. Wing tip
• D. Fuselage

Answer: (A)

Auxiliary fuel tanks are placed in the wing center section because this area provides the best combination of space, structural support, and favorable weight distribution. The center section is strong and wide enough to house additional tanks without interfering with the control surfaces, engines, or landing gear. Having extra fuel near the fuselage helps keep the aircraft’s center of gravity stable as fuel is burned, and it minimizes shifting loads on the wing during flight. Placing tanks in the wing tip would move weight outward, affecting roll characteristics and increasing stresses on the outer wing, while locating them in the fuselage isn’t as practical for wing fuel management. So, the wing center section is the logical and effective location for auxiliary tanks.
