What does the term "Fuel Reserve" refer to as per AFI 11-202 Volume 3?

The term "Fuel Reserve," as defined in AFI 11-202 Volume 3, refers to the extra fuel carried beyond what is planned for the flight. This additional fuel is critical for ensuring safety and provides a buffer in case of unexpected circumstances, such as changes in weather, delays at the destination, or the need to divert to an alternate airport. Carrying a fuel reserve helps mitigate risks associated with fuel consumption variability and operational uncertainties, ensuring that there is enough fuel to safely complete the flight even if conditions change.
