OUTLINE OF CURRENT CLASS B ON COMBINED VIDEO MAPS

This slide is to give you an idea of how much – or how little – of our airspace is covered by Class B. We have 3 major and 2 other extremely busy corporate airports in close proximity. In every situation where we leave Class B, it is due to volume and the effort to stay out of a hold.

slide3

CLASS B WITH DETAILS

This is a detailed diagram of the Class B. There’s a reason for all the cutouts – Linden airport, the Hudson River Corridor, helicopter traffic, Farmingdale Airport – but there are a lot of them!

slide4

EWR RWY 4 VECTOR PATTERN, STAYING IN CLASS B

EWR RWY 4 final with Class B used the way it was designed – once aircraft enter, they do not exit. The three streams of traffic are coming from Boston Center (Sparta), New York Center (Broadway), and Washington Center (Yardley).

slide5

EWR RWY 4 VECTOR PATTERN, LEAVING CLASS B

When volume increases, aircraft enter and exit the Class B. Wind conditions are also a factor; for example, when we have a tailwind at 3,000’ and a headwind at 2,000’, the controllers will descend below the floor of Class B in order to get all the aircraft in the same wind condition.

slide6

EWR RWY 22, STAYING IN CLASS B

This is the vector pattern for RWY 22. When it is not too busy, aircraft stay in Class B.

slide7

EWR RWY 22, LEAVING CLASS B

Here is a more usual occurrence. Aircraft from the south are vectored behind traffic coming from the north. This is especially true in the early afternoon, when the heavy jets come from overseas. It doesn’t take more than 5 heavy jet aircraft being sequenced for final in the northern part of the airspace for the traffic from the south to have to exit the Class B to follow them.

slide8

EWR USING RWY 11 AS SECONDARY LANDING RWY, NE FLOW

When using RWY 11 and the TEB ILS RWY 6, RWY 11 traffic must be descended below the traffic on the TEB localizer.

slide9

LGA CLASS B ISSUES – HPN PROPOSAL

Because HPN is at the lateral limit of Class B, and below the vertical limit, IFR arrivals on either the ILS RWY 16 or 34 receive no protection from VFR arrivals transiting at 2,000 feet. The additional workload of calling traffic is significant. Any revision of Class B should include protection down to 2,000 feet in this area.

slide11

LGA LOCALIZER RWY 31

When volume builds, LGA will descend below the floor of Class B to maintain vertical separation. There is always a strong wind on the downwind on this flow, so different altitudes are used to maintain safety. It is possible to run this final without using 2000’, but it is much less efficient and causes gaps on final.

slide12

LGA ILS RWY 13 WHEN EWR IS USING ILS RWY 22

When EWR is using ILS RWY 22L and LGA is using ILS RWY 13, LGA must maintain vertical separation from the EWR final. This increases the likelihood that traffic will be vectored further out of the Class B. This configuration is used only a few times a year, mostly in bad weather and always in strong wind.

slide15

JFK RWY 4 ARRIVALS

Due to volume, arrivals to RWY 4 are frequently vectored out of the lateral limits of Class B.

slide16

JFK RWY 22 DUAL FINALS

When using dual approaches to RWY’s 22L and 22R, JFK must descend below Class B in order to maintain vertical separation between the two streams. When there is enough volume to warrant using this procedure, the aircraft are often vectored out of the lateral limits as well. The airspace outlined in red is allocated from LGA Area at 2,000 and 3,000’ only.

slide17

CLASS B 25 NM PROPOSAL

We want to expand the Class B to at least 25 NM around the three major airports, possibly 30 to encompass more of the EWR and HPN traffic. We would also like to remove the FRG cut-out at 4,000’ and take the floor of the Class B to 2500’. We would need to design corridors to capture the EWR RWY 11 final and the HPN final where the lower limit would be 2,000’.

This slide shows the corridors to capture the EWR RWY 11 final and the HPN final where the lower limit would be 2,000’.
