In a single point refueling system, where is the receptacle used to fill all tanks?

• A. Bottom receptacle used to fill all tanks
• B. Top of the fuselage
• C. Nose cone port
• D. Wing root port

Answer: (A)

Single point refueling uses one port to feed all fuel tanks through an internal distribution system. The receptacle is placed at the bottom of the fuselage because this single, central access point works well with standard ground fueling equipment and allows the fuel to flow by gravity into the shared manifold, helping ensure consistent filling of all tanks. Exterior top locations, nose cone, or wing root ports would complicate access, venting, and distribution, making it harder to guarantee that every tank is filled from one point. So the bottom receptacle used to fill all tanks is the correct choice.
