KJFK is in a part of Queens, NY, known as Jamaica. In fact, it sits right next to Jamaica Bay. For people unfamiliar with local geography, that location is probably too specific. New York, NY would work better.
I have not updated my ANRB databases, so I will install this update. But I am concerned about the inaccuracies being described by others. How can it occur that so many new errors were introduced?
I use PlanePlotter for primary aircraft identification and data sharing, so even if ANRB's database is missing or dead wrong, the errors have no direct effect on my monitoring except possibly some inconvenience. Still, it's hard to recommend ANRB with a straight face knowing about the data problems it has.
