For some time now, FlightAware has been dropping substantial blocks of data. For example, look at N631S, flight from KBDR to KVKX on 8/19/11. If you look at the Flight Track Log you will find data dropped from 16:56 to 17:54. The program simply connects the last data point at 16:56 to the first at 17:54 with a straight line.
The resulting inaccurate track is useless. This is not an isolated event. Substantial data dropout has been occurring on flights for at least a month.
Why is this happening? Is there a problem at FlightAware or is the FAA the problem? What changed and how can it be fixed?
