The One-Third Fuel Rule
1/3 Out1/3 Return1/3 Reserve
Never use more than 1/3 of your fuel getting to your destination. Keep 1/3 for the return trip and 1/3 as reserve for unexpected conditions, diversions, or current/wind effects on fuel consumption.
Distances are great circle (straight line). Actual passage distances will be longer due to navigation around land, channels, and traffic separation. Fuel estimates assume calm conditions.
