## NY/NJ/PHL Metropolitan Area Airspace Redesign

**Record of Decision (ROD)**
**Announcement **
**Congressional Briefing**

- Name: Steve Kelley
- Date: September 5, 2007

**Notes:**
NAR is a program that designs airspace – that’s not what we’re talking about in this briefing – we’re talking about the total agency process of changing airspace

## 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

**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**

**Notes:**
EWR and JFK also have arrival benefits from expanded awareness of the sequence, but they have improved runway usage, so the effect is harder to see.  LGA is the example here because no other system change has arrival benefits.

## Integrated Airspace Improves Departures

**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**

**Notes:**
EWR and JFK also have arrival benefits from expanded awareness of the sequence, but they have improved runway usage, so the effect is harder to see.  LGA is the example here because no other system change has arrival benefits.

## Flexibility in Routing Minimizes Impact of Severe Weather

**Flexibility in Routing Minimizes Impact of Severe Weather**

**Original Routing**

**Reroutes due to weather**

- Available reroutes Current airspace
- Additional 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

## Raw Data Noise Changes - Selected Alternative with mitigation as compared to the No Action Alternative (2011)

## Raw Data Noise Changes – Philadelphia Area

## Raw Data Noise Changes: South New Jersey Area

## Raw Data Noise Changes : Newark and Staten Island Areas

## Raw Data Noise Changes: Newark North Area

## Raw Data Noise Changes: LaGuardia and Westchester Areas

## Summary of Rationale for Selected Project

- Integrated Airspace as the Selected Project because it...
- Offers the most significant operational benefits
- Provides a new way to manage air traffic control
- Aligns airspace with its functionality
- Serves as a foundation for the future, supporting adaptive use of the airspace
- Reduces emissions from aircraft
- Reduces the number of people exposed to noise over No Action
- Embraces emerging technology
- Fits flexibly into any of the Agency's facility plans
