During cruise fuel planning, which action supports efficiency and reserves?

• A. Refuel mid-cruise at every waypoint.
• B. Ignore route efficiency and fly direct between waypoints.
• C. Monitor fuel burn, compare actual burn to plan, consider route adjustments for efficiency and reserves.
• D. Carry no reserves and burn more fuel intentionally.

Answer: (C)

Efficient cruise fuel planning hinges on tracking actual fuel burn against the plan and adjusting the route to improve efficiency while preserving required reserves. By comparing what you actually burn with what you estimated, you can detect deviations early and decide whether changes to altitude, wind-aware routing, or shorter segments could reduce consumption without compromising safety. If the real burn runs higher than expected, making informed route adjustments helps you maintain the necessary reserves for contingencies like weather, diversions, or holds. This approach balances efficiency with safety, avoiding unnecessary mid-course refueling, unnecessary direct routing that ignores favorable winds, and the risk of operating without sufficient reserves.
