What component prevents APU fuel starvation?

What component prevents APU fuel starvation?

• A. The APU is designed to operate without a fuel system
• B. A dedicated fuel system with a pump and filter assembly
• C. The main aircraft fuel tanks supply the APU
• D. The APU uses gravity-fed fuel from the wings

Answer: (B)

The component that prevents APU fuel starvation is a dedicated fuel system with a pump and filter assembly. This system is essential for ensuring that the APU receives a consistent and reliable supply of fuel throughout its operation. The dedicated fuel system is designed specifically for the APU's requirements, facilitating the delivery of fuel from the aircraft's main fuel system or tank. By utilizing a pump, this system can maintain adequate fuel pressure, which is crucial for the APU to start and operate efficiently. The filter assembly is equally important as it removes impurities from the fuel, preventing clogging and ensuring that the fuel system operates smoothly without interruptions that could lead to starvation. This specialized setup is vital, as it distinguishes the APU's fuel needs from those of other aircraft systems. While some other options imply alternative methods of fuel supply, they lack the reliability and specificity that a dedicated fuel system provides, which is designed to meet the unique demands of the APU.
