Contingency fuel is an important component of flight planning, as it addresses uncertainties that may arise during a flight. Specifically, it serves as a buffer against factors such as unforecast winds and air traffic control re-routes that can significantly impact a flight’s fuel consumption. These external elements can cause a flight to use more fuel than anticipated, making the inclusion of contingency fuel essential for ensuring that the aircraft has sufficient fuel reserves to adapt to these unexpected situations.

Incorporating contingency fuel into flight planning helps enhance safety, as it mitigates the risk of running low on fuel due to changing conditions en route. This amount is typically calculated based on statistical data regarding wind patterns and the likelihood of required deviations from the planned flight path.
