What is the role of splash plates in a fuel tank?

Splash plates play a crucial role in minimizing fuel slosh within an aircraft fuel tank. When an aircraft maneuvers—whether during acceleration, deceleration, or in turbulence—the fuel inside the tank tends to move and can create sloshing motion. This movement can lead to inconsistent fuel supply to the engine, which may affect engine performance and stability.

By incorporating splash plates, the design of the fuel tank helps to break up the fuel movement and streamline the fuel flow to the tank outlet. This stabilization allows for a more consistent delivery of fuel to the engine, ensuring that the engine receives a reliable and steady supply of fuel regardless of the aircraft's maneuvers. Therefore, the function of splash plates is essential for both operational efficiency and safety in aircraft fuel systems.
