Why We Need to Redesign Airspace

• Routinely, the New York and Philadelphia
  metropolitan areas airports are among the top
  10 delayed
• Lack of alternate routes closes off airspace in
  cases of severe weather
• Multiple facilities fragment arrival and
  departure corridors
• Complexity and congestion continue to be issues
  even with post-September 11 downturn

4
Implementation Overview

• Implementation Plan began developed immediately
  following the signing of Record of Decision
  (September 5, 2007).
• Initial changes to airspace were implemented on
  December 19, 2007
• Implementation approach was segregated into four
  stages in the ROD
• Each stage will take from 12 to 18 months and
  stages will overlap

5
ROMA (or Route Optimization and Mitigation
Analysis)

• Considers all headings within an identified range
• Evaluates noise impact for every possible
  combination of headings
• Identifies exact headings for minimal impact

Motivation for Westgate Expansion

• KEY ISSUES WITH CURRENT WESTGATE
• ELIOT overload currentlyserves 3 airways and
  BRNAN
• PARKE complexity climbingand descending
  aircraft
• BIGGY complexity climbingand descending
  aircraft
• RBV crossing traffic increased volume from JFK
• IMPACTS
• Westgate a chokepoint during peak demand
• Passback of Miles-in-trail (MIT) restrictions to
  NY metro airports
• Potential adverse impact on PCT arrivals

Stage 2 Minor Airspace Realignment
11
Key Elements of Stage 3 (5/11/2010 11/9/2011)

• Relocate and Expand North Airways
• Redesign NYNJPHL North Corridor (ZNY, N90)
• Reroute Northbound PCT Departure Routes

• Facilitating Stage 4 Elements
• Apply Altitude Restriction on LGA to Separate NY
  and PHL Traffic
• Provide Arrival Coordination for Traffic Flow
  Management
• Apply Terminal Separation Rules (allowing less
  stacking and MIT)
• Additional MXE Departure Fix
• Arrival Shift LGA and EWR
• Facility Boundary Adjustments at ZNY, ZBW, ZDC,
  N90
• Implement 3rd Dispersal Heading at EWR

Next Steps

• Continue to address and resolve legal and
  political challenges
• Written Reevaluation with respect to new
  Information
• Respond to GAO Recommendations Report due July
  31, 2008
• Pending litigation Extension Granted for
  Briefing Schedule
• Continue safety assessment of all changes
• Facilitate an improved collaborative relationship
  with all stakeholders
• Develop Airspace design activities with adjacent
  facilities
• that enhance the benefits of integration
