When Minimum Fuel Required (MFR) equals Fuel On Board (FOB), the flight must:

• A. Be enroute to the scheduled destination or proceed to the designated diversion airport
• B. Continue to operate with reduced MFR
• C. Return to origin airport
• D. Land at the nearest suitable airport

Answer: (A)

The key idea is fuel planning: Minimum Fuel on board is the amount needed to complete the flight to the destination or to the designated diversion airport, including required reserves. If the fuel on board exactly equals that minimum, you have just enough to reach the planned destination or the prescribed diversion point, with no extra margin for further holds or deviations. In this situation, the proper action is to continue toward the scheduled destination or divert to the designated alternate as planned, since you cannot confidently add additional legs or landings without risking running out of fuel. Landing at the nearest suitable airport, returning to the origin, or operating with a reduced minimum would imply you have more fuel flexibility than you actually do. You should only deviate to a closer airport or alter the plan if safety or ATC instructions dictate it.
