What is a Metroplex?

A Metroplex is a geographic area that includes several airports, serving major metropolitan areas and a diversity of aviation stakeholders such as National Airspace System users, the FAA, businesses, and airport operators. Congestion, airport activity in close geographical proximity, and other limiting factors, such as environmental constraints combine to reduce efficiency at busy Metroplex sites.

The FAA and aviation experts analyze the operational challenges of Metroplexes and explore opportunities to optimize airspace and procedures. To learn more about Metroplexes, please visit the Metroplex page.
