Distance—kilometres
Miles—statute miles
Nautical—nautical miles
Bearing—initial heading
How it works
The calculator loads the airport coordinate list once, then computes the haversine great-circle distance between your two choices and applies the flight-time model described on the method page: 0.42 hours of ground and climb allowance plus distance divided by 805 km/h.
Every calculation happens in your browser. Nothing you type is sent anywhere, and there is no request to any server after the page loads.
