Work out range of aircraft instantly with clear inputs, formula shown and shareable results.
Range is endurance multiplied by ground speed. Because endurance depends only on fuel and burn rate, wind changes range without changing how long you can stay airborne — a 15 knot headwind on a 135 knot aircraft costs about 11% of the distance.
Range
Range = (usable fuel / burn per hour) x (TAS - headwind)
Aviation results are planning estimates only. Always verify take-off, landing, fuel, weight and balance figures against the certified Aircraft Flight Manual, current performance charts and applicable aviation regulations before flight.
Because specific air range varies with weight, altitude and speed. Working through endurance and ground speed keeps the wind effect explicit.
Only up to the best-range speed. Beyond it, drag rises faster than the speed gain, so range falls even though the trip is quicker.
