Metroplex: Improving Traffic Flow in Complex Airspace

A key NextGen goal is to safely improve the overall efficiency of the National Airspace System by increasing efficiencies at metropolitan areas, or metroplexes, with multiple airports and complex air traffic flows. The FAA's goal is to improve the way aircraft navigate these complex areas to make flight routes and airport access more efficient. This new way of operating has the potential to reduce fuel burn and emissions, and improve on-time performance at the metroplex and between the departure and arrival airports, known as city pairs.

Each metroplex includes one or more commercial airports with shared airspace that serves at least one major city. In collaboration with the aviation industry the FAA has identified 21 metroplexes where improved performance could benefit not only the region, but the entire national airspace system.

The FAA and the aviation industry then prioritized 12 initial metroplexes where improvements were expected to yield near-term benefits. As the program evolved, three sites were deferred and two additional sites were added, resulting in the 12 active or complete metroplex sites reflected in the map below. Through the Metroplex program, the FAA collaborates with aviation stakeholders to improve regional traffic movement by optimizing airspace and procedures built on precise satellite-based navigation.

City-pair performance is the most direct way for airline operators to connect two markets. In collaboration with the aviation industry, the FAA identified and is measuring how NextGen metroplex improvements provide benefits between city pairs.
