What is the minimum fuel requirement at the decision point for a flight using the RCF procedure to proceed to the Destination 1 aerodrome?

The minimum fuel requirement at the decision point when using the RCF (Reduced Contingency Fuel) procedure is designed to ensure that an aircraft has sufficient fuel to safely reach its intended destination, with additional allowances for unforeseen circumstances. Choosing the total of trip fuel, contingency fuel, alternate fuel, and final reserve fuel guarantees that the aircraft has the necessary resources to complete its flight without compromising safety.

This comprehensive fuel calculation takes into account not only the fuel required to reach the destination but also contingencies that might arise, which could include diversions to an alternate aerodrome or unexpected delays. By having contingency fuel aboard, the flight crew can manage any unplanned changes in conditions, such as altered weather patterns or air traffic control instructions. Additionally, final reserve fuel ensures that there is a safety net in case of emergencies, allowing the aircraft to perform necessary maneuvers or hold patterns if required.

In contrast, calculating solely trip fuel to Destination 1 lacks the additional safety margins needed for safe operations under potential contingencies. The other fuel options do not offer a complete picture of what is necessary at the decision point, potentially leaving the aircraft vulnerable to risks that could arise during flight.
