Record of Decision Issued – September 5, 2007

• The Selected Project for this study is The Integrated Airspace Alternative with the Integrated control complex (ICC) variation.

• This is the final stage of this study which has been on-going for over 9 years

• Procedural adaptations for noise abatement (mitigation measures) will also be implemented

• Draft Environmental Impact Statement DEIS was published in December 2005

• Comments were taken on the DEIS and some of those comments were used in developing the noise mitigation measures

• In April of 2007 the FAA identified its Preferred Alternative and provided analysis of the mitigation measures

• Final Environmental Impact Statement (FEIS) was published on August 3, 2007



Increased Number of Jet Routes Reduces Delay

Integrated w/ ICC:

•Increased number of jet routes

•Increased number of access points

•Less competition for departures means decreased delay

Current System:

•Few jet routes for departures

•Access is limited

•Competition for resources means increased delay



JFK Access to Westgate Decreases Complexity

Integrated w/ ICC:Current System:

•JFK traffic crosses through departures from LGA, EWR, TEB, etc.

•Long ground delays necessary to maintain safe and orderly flow of traffic

•Stacked flows are more efficient and less complex

JFK flights JFK flights



Delay Savings with New Usage of Runways

Dependent IFR approaches

Idlewild Climb for capable jets

Dual Arrivals

Integrated w/ ICC:

•Dual arrivals to EWR 04/22

•Increased use of EWR 11

•Right turn off JFK 31R

•Efficient use means reduced delay

Current System:

•Conflicting flows restrict use of runways

•Inefficient use of runways means increased delay

EWR JFK



Delay Savings with Fanned Departure Headings

Integrated w/ ICC:

•Increased departure headings at EWR, LGA and PHL

•Less time waiting to depart

•Reduced engine emissions while aircraft idle

Current System:

•EWR and PHL have single heading for departures

•Long waits on the taxiway waiting a turn to depart

EWR



Integrated Airspace Improves Arrivals

Sequence known today

Sequence known w/ ICC

Integrated w/ ICC:

•Earlier Sequencing means

•Flights remain higher longer

•ATC actions to order flights are done at higher altitudes

•Lower fuel burn

•Decreased emissions

Current System:

•Short sequencing time results in increased maneuvering of aircraft at low altitudes

~ 30 min



Integrated Airspace Improves Departures

Integrated w/ ICC:

•Unrestricted climb for departures

•Reduced complexity for ATC

•Stacked departures at access point

•Reduced fuel burn and emissions

•Reduced delay

Current System:

•Departures held down to lower altitudes

•Maneuvering at low altitudes to line up for jet route access

•Single line over departure fix



Flexibility in Routing Minimizes Impact of Severe Weather

Original Routing

Reroutes due to weather

Available reroutes Current airspaceAdditional available reroutes in Integrated w/ ICC Alternative

Integrated w/ ICC:

•Increased access to en route airspace means more options in severe weather situations

•Flexibility to take off and fly around the weather

•Reduced delay

Current System:

•Airspace constraints result in increased congestion when severe weather is present

•Delays escalate



Summary of Changes that Reduce Delay

• More jet routes with increased access• JFK direct access to westgate rather than crossing flows• Improved use of available runways• Fanned headings for departures• Arrival efficiencies

• Arrivals remain at higher altitudes longer

• Improved sequencing manages arrival flows better

• Departure efficiencies• Stacked departures increases efficiency

• Unrestricted climb reduces complexity

• Flexibility to manage delays in severe weather



Other Benefits of the Selected Alternative

• Integrated Airspace saves over $248M annually in direct operating costs.

• An additional $37M annually will be saved due to flexibility in severe weather events

• More efficient handling of aircraft - results in less fuel burned

• Implementation of the Preferred Alternative with mitigation reduces the population exposed to average noise of 45 DNL or more by over 600,000



Noise Exposure Tables

• Noise exposure tables providing comparative data between the No Action and all alternatives have been available on the project website

• Those tables were adjusted in April 2007 to provide the comparative results of our mitigation measures

• The following chart represents a visual mapping of those tables• These dB changes provide an additional level of information

beyond that required by NEPA
