What are FlightAware’s dotted-line flight tracks for upcoming flights based on? Based on some pre-flight document of the planned flight track made by the airline itself before each flight? Or based just on FlightAware’s own estimate of the flight track based on previous flights and wind data? Or based on what?
Yes, typically flight plans filed in advance with ANSPs.
Thanks! Would airlines typically file those flight plans with ANSPs only a day or so before each flight? Or would they file flight plans for say a flight one week in the future? And if so, is there any website or other way (even by telephone inquiry) for the public to access that more future planned flight track information?
