It is known that, due to the nature of the system, it takes about five minutes for aircraft position data to be recieved, processed by FlightAware, and updated in the tracking system. This causes the user to see a slightly less than real time display of information with about a five minute lag between an aircraft’s displayed position and actual position. This applies to both individually tracked flights and the ATC style view of local traffic in the vicinity of an airport.
My suggestion is that FlightAware incorporates a feature, that can be toggled on or off by the user, which projects the path/position of an aircraft about five minutes ahead of the current data based on heading and groundspeed. While this is not a perfect solution, it may allow for a more accurate display of current aircraft position. This is especially true when aircraft are approaching an airport when a five minute delay can mean the difference between vectors on approach and short final.
I’d be interested to hear what other members and FlightAware staff think of this.
