For example, I've started playing the KJFK the past couple of days. Particularly arrivals coming in from the East are coming in at 2300', and all others are at 5000' and below already when they're handed to me, which can be 50-60nm from the airport. That seems awfully unrealistic to me? Maybe I'm completely wrong? Some of the STAR routes bring them in across the departure runways and since they're at altitudes of 5000' and below you can get a lot of conflict alerts from departing aircraft? So pretty much there's nothing to do with arrivals coming in on their STARs until they get up to the airport and you bring them around to angle them in for the ILS approach?
I've also had them at altitudes of 5000' and below when they come in from center on KATL. Let me know if I'm doing something wrong or if I'm missing something here.
