🛢️ Fuel Endurance & Range Planner
Hours aloft and range with your reserve intact
About this calculator
Endurance is how long you can stay up, range is how far that time takes you, and the reserve is the fuel you never plan to touch. Enter your usable fuel, burn rate, and cruise speed to see your endurance to reserve and your no-wind range. The reserve defaults to 45 minutes, the smart minimum for any flight.
Tip: lean the mixture per your POH in cruise. Most pilots burn more than book because they fly rich of peak the whole way.
