Where are the main fuel tanks located on the 787?

• A. In the tail section.
• B. In the wings and center wing tank as part of the fuel system network.
• C. In the fuselage along the cockpit area.
• D. In the engine nacelles.

Answer: (B)

The main fuel is stored primarily in the wings, with an additional center wing tank as part of the fuel system network. The left and right wing tanks are integrated into the wing boxes, and the center wing tank sits between them to increase capacity and help manage center of gravity. This arrangement keeps most of the fuel weight near the wings, feeds the engines through the fuel pumps, and avoids placing large tanks in the tail, fuselage cockpit area, or engine nacelles.
