What feature is common in low-wing aircraft regarding fuel systems?

• A. They have no fuel pump
• B. They always have a fuel pump
• C. They may have a fuel vent issue
• D. They are not affected by fuel starvation

Answer: (B)

Low-wing aircraft typically have a fuel system design that includes a fuel pump as a standard feature. This is primarily due to the positioning of the fuel tanks, which are often located below the level of the engine. Because of this design, a fuel pump is necessary to effectively move fuel from the tank to the engine, ensuring that it can overcome the gravitational pull and maintain a steady fuel supply under all conditions. This is important for maintaining engine performance and reliability, especially during climbs, descents, or when the aircraft is maneuvering. Furthermore, having a fuel pump helps prevent issues such as fuel starvation, which can occur if the fuel relies solely on gravity for delivery. The presence of a fuel pump in low-wing aircraft contrasts with designs found in some high-wing aircraft, where fuel can sometimes flow by gravity alone. However, many high-wing designs also utilize fuel pumps to ensure consistent fuel delivery. Thus, the presence of a fuel pump in low-wing aircraft is a critical feature for their operational effectiveness.
