Which fuel category covers contingencies beyond planned trip fuel?

• A. Trip fuel
• B. Alternate fuel
• C. Reserve fuel
• D. FOB

Answer: (C)

Fuel planning involves several categories that define how much fuel a flight needs. Trip fuel covers the fuel required to complete the planned leg from takeoff to landing at the destination. Alternate fuel accounts for reaching a standby airport if the destination cannot be used. Reserve fuel is the extra amount intended specifically for unforeseen events that extend the flight beyond the plan—like headwinds stronger than forecast, weather reroutes, or delays requiring holding. FOB isn't a planning category; it’s simply the current fuel on board. Because reserve fuel is the extra layer designed for contingencies beyond the initial trip plan, it is the correct choice.
