I’ve noticed that over the oceans, where there isn’t an ADS-B receiver to pinpoint a position and FlightAware needs to use estimates, it doesn’t then “correct” the track so far when an actual position is available over land. The estimated ETA then doesn’t take account of where the aircraft actually is but seems to rely on the original guesstimate from the flight plan
I’m tracking a flight from Dubai to Australia, the track on another ADS-B website runs out over the Indian Ocean but re-appears over Male in the Maldives but by then the FlightAware track is hundreds of miles adrift from the actual. Is it not possible to apply corrections, much as pilots would have corrected for guesstimates from dead reckoning or early inertial navigation systems. Or am I missing something ?
