The system that prevents fuel from sloshing around in the tanks is baffles. Baffles are internal structures designed to create partitions within the fuel tank, which help to minimize the movement of fuel as the helicopter maneuvers. This is particularly important during flight, as excessive slosh can affect the center of gravity and stability of the aircraft. By breaking up the fuel into smaller compartments, baffles can effectively reduce the dynamic movement of the fuel, enhancing overall safety and performance.

In contrast, flapper valves serve a different purpose, mainly regulating the flow of fuel and preventing backflow. Ejector units are typically used for fuel transfer or circulation rather than to manage slosh. Pressure transducers monitor fuel levels and pressures but do not have a role in physically preventing the movement of fuel within the tank.
