Baffles in an aircraft fuel tank are crucial components designed to manage the movement of fuel within the tank during various flight maneuvers, such as turns, climbs, and descents. Their primary function is to maintain fuel balance during flight by preventing fuel from sloshing excessively from one side of the tank to another. This balance is essential for several reasons, including ensuring that the aircraft remains stable and properly centered, which is vital for safe flight operations.

When fuel is allowed to move freely within the tank, it can shift significantly, potentially leading to an uneven distribution of weight. This imbalance can affect the aircraft's performance, handling characteristics, and overall safety. By utilizing baffles, the design helps to contain and control this movement, allowing for a more stable center of gravity throughout a flight.

While factors like consistent fuel temperature, increased fuel pressure, and maximum fuel volume are important within an aircraft fuel system, they are not the primary purpose of baffles. Their main focus remains on stabilizing fuel movement to maintain balance as the aircraft operates through various flight conditions.
