What component prevents fuel from traveling outboard during low-wing maneuvers?

The correct answer is the flapper valves. In aircraft systems, particularly those with low-wing configurations, flapper valves are crucial in maintaining fuel management during various flight maneuvers. When the aircraft is in a low-wing position, such as during turns or certain levels of bank, these flapper valves work to prevent the fuel from sloshing away from the fuel pickup area.

The design of the flapper valves allows them to open towards the fuel tanks, enabling fuel to flow to the fuel pumps when needed, but they automatically close when there is a risk of fuel moving away from the pick-up, thereby ensuring that there is always a supply of fuel available even in challenging flight attitudes. This minimizes the risk of fuel starvation in critical situations, ensuring engine performance is maintained.

In contrast, fuel pumps are responsible for moving the fuel from the tanks to the engine but do not regulate fuel movement in response to aircraft position. Fuel filters are essential for removing impurities from the fuel system but do not affect fuel dynamics during maneuvers. Check valves allow for unidirectional flow and typically focus on preventing backflow in the fuel lines but aren’t specifically designed to handle the issues related to fuel movement in low-wing configurations. Thus, the function of fl
