JFK Traffic Management Tips

Departures:

JFK launches the bulk of their departures between 4:00pm local and 7:00pm local.

Take action to ensure that JFK tower is departing international traffic, when domestic departures are being severely restricted by weather.

Arrivals:

NTMS's should monitor JFK arrival pushes closely. JFK tower has a tendency to favor departure pushes, and if the departure and arrival pushes overlap, holding can occur. We need to ensure that JFK continues to favor arrivals even if it means that JFK tower assumes a departure delay posture. Departure delays of less than 30 minutes are considered acceptable.

When weather and winds force JFK to utilize the ILS RWY13L approach, LGA must change to an ILS RWY13 approach. In this runway configuration, due to wake turbulence, LGA must use extra spacing between arrivals to allow for LGA heavy jet departures. This will decrease the arrival acceptance rate at LGA. If traffic demand is light, you can expect the runway change to take less than 5 minutes. If the traffic demand is heavy, the runway change will take between 15 and 20 minutes to allow N90 to clear the airspace prior to conducting operations for the ILS RWY13L approach at JFK. During this transition you can expect holding delays for JFK and LGA.
