What is used within each fuel cell to prevent fuel from shifting during flight?

• A. A flange
• B. An anti-surge baffle
• C. Fuel vents
• D. Honeycomb panels

Answer: (B)

The correct choice refers to the use of an anti-surge baffle within each fuel cell, which plays a crucial role in maintaining fuel stability during flight operations.

Anti-surge baffles are designed to minimize the effects of fuel movement caused by changes in the aircraft's orientation and acceleration. When an aircraft maneuvers, the fuel within the cell can shift, potentially leading to an imbalance in the center of gravity or even affecting the aircraft's performance. These baffles partition the fuel cell, allowing fuel to remain more stationary and helping to prevent sloshing. This stabilization is essential not only for operational effectiveness but also for ensuring safety and optimizing fuel management throughout various flight phases.

Understanding the role of anti-surge baffles is key for maintaining the integrity of fuel systems in aviation, as they are critical in ensuring consistent fuel delivery to the engines and enhancing the overall reliability of the aircraft's fuel system during dynamic flight conditions.
