When is a fuel check performed?

• A. If flight is an hour or longer
• B. If flight is under 30 minutes
• C. For international flights only
• D. After landing

Answer: (A)

Fuel checks are about making sure you have enough fuel for the planned trip plus the required reserves and any contingencies. They’re especially important on flights that are longer, because the chance of delays, holding, weather diversions, or other detours increases with time. That’s why a fuel check is performed when the expected flight time is an hour or longer—you want to confirm the fuel on board covers trip fuel plus reserves for a potential alternate or holding.

For shorter flights, the standard preflight fuel calculation usually suffices, so an additional fuel check isn’t typically required. It isn’t tied to international flights specifically, and doing a check after landing wouldn’t help ensure safe departure.
