Flight operations are always carried out with adherence to strict weight and balance limits, where everything from fuel levels to storage limits are carefully controlled to ensure aircraft maintain stability, efficiency, and safety throughout the entire journey. For example, aircraft cannot safely land if they are too heavy, such as if they have a large amount of unspent fuel. In the circumstance of an emergency where pilots have to make a landing long before reaching their destination, a fully fueled aircraft may face the risk of structural damage or difficulty in stopping upon touchdown. To address this issue, large commercial jets are regularly equipped with fuel dumping systems, allowing them to release excess fuel in a controlled manner.
