Modification of the Phoenix Class B Airspace Area; Arizona

This action modifies the Phoenix, AZ, Class B airspace area. Specifically, this action lowers the ceiling to 9,000 feet mean sea level (MSL) and expands the arrival extension boundaries to 30 nautical miles (NM). This will ensure the containment of the Standard Terminal Arrival Routes (STAR) at the Phoenix Sky Harbor International Airport (PHX), and correct the inefficiencies of several existing areas identified during public meetings, and reviews of the airspace by the Phoenix Airspace Users Work Group (PAUWG) and Phoenix Terminal Radar Approach Control (TRACON). The FAA is taking this action to improve the flow of air traffic, enhance safety, and reduce the potential for midair collision in the PHX Class B airspace area, while accommodating the concerns of airspace users. Further, this effort supports the FAA's national airspace redesign goal of optimizing terminal and en route airspace areas to reduce aircraft delays and improve system capacity.
