The purpose of the NY/NJ/PHL Metropolitan Area Airspace Redesign project was to increase the efficiency and reliability of the airspace structure and the Air Traffic Control (ATC) system, thereby accommodating growth while enhancing safety and reducing delays in air travel for the NY/NJ/PHL Metropolitan Area. The Airspace Redesign project was intended to modernize the structure of the NY/NJ/PHL air traffic environment while laying a foundation for achieving the Next Generation Air Transportation System (NextGen) in an environmentally responsible manner.
While four stages of implementation were originally planned, FAA paused the project in 2012 in light of air transportation system changes in the intervening years. While several beneficial elements of the project were implemented, the National Airspace System evolved significantly between the 2007 EIS and 2012. New NextGen capabilities such as Time Based Metering and advanced satellite based navigation procedures, increasing consolidation of the airline industry, changes in system use, and evolving traffic projections resulted in new and different airspace and procedures requirements. As a result, the FAA suspended the project in May 2013. The FAA has determined it is appropriate to end implementation and has prepared a Written Re-evaluation and Record of Decision (PDF) in December 2020. There are no current plans for further work on the project.
