A student proposes using final-reserve fuel to cover an expected en-route shortfall. Explain why this does not follow the fuel-planning rule in the material.

### Why this is right The supplied rule explicitly treats final reserve as a minimum that must remain on landing. Planning to consume it en route would contradict that purpose and would leave the planned landing amount unavailable. ### The concept Fuel components are separated by purpose. Trip fuel is for the planned route, contingency is 5 percent of trip fuel, and alternate fuel is assigned to the alternate plan. Final reserve is the 45-minute holding-speed amount designated as the absolute minimum upon landing. Therefore, a forecast en-route shortfall should not be solved by treating this minimum as planned route fuel under the stated material. ### What a good answer covers - State that final reserve is a landing minimum. - State that it is not planned for en-route use. - Distinguish it from trip, contingency, and alternate fuel. ### Terms - **En route**: Along the planned flight route. - **Final reserve**: The minimum fuel intended to remain on landing. ### Remember Keep final reserve protected as the stated landing minimum.
