Estimate contingency fuel using trip fuel and contingency percentage. This free aviation calculator helps pilots add an extra planning margin for variations and uncertainty.
Enter trip fuel and the contingency percentage to calculate contingency fuel required.
This calculator is a planning aid. Always use the fuel planning requirements and procedures appropriate to the operation.
Contingency fuel is additional fuel planned to account for minor variations and uncertainty during flight. It can help cover things like small routing differences, winds that differ from forecast, or other reasonable operating variations.
Planning contingency fuel separately helps pilots keep the total fuel plan organized and makes it easier to distinguish between trip fuel, reserve fuel, and other fuel categories.
No. Contingency fuel and reserve fuel serve different purposes and are often planned separately.
Yes. A common planning method is to calculate contingency fuel as a percentage of trip fuel.
That depends on the type of operation, applicable procedures, and planning method. This calculator lets you choose the percentage you want to apply.
This calculator is a planning aid. Pilots should always use approved aircraft data, applicable requirements, and sound operational judgment.
