Time & Fuel Planning

Calculating accurate time enroute and fuel requirements is the foundation of navigation. It ensures you reach your destination with legal reserves.

The Math

Time = Distance / Ground Speed. Fuel = Time × Burn Rate. Always verify Ground Speed against forecast winds aloft.

Reserve Fuel

Legal requirements (e.g., VFR Day: +30 mins, VFR Night: +45 mins) are minimums. Personal minimums should often be higher, especially for cross-country flights.
