Avgas range each cell = 1 hr of cruise · width scales with speed

Bars show published still-air range: select a cell to view cruise-hours and fuel usage. Endurance is full tank at the displayed cruise burn rate; the extra is reserve and economy margin. Estimates only. Always verify against the POH.
