Metroplex Initiative

A metroplex is a metropolitan area where mul­tiple airports are located. The Southern California metroplex, for example, contains more than a dozen general aviation airports as well as large commercial airports such as Los Angeles Interna­tional Airport (LAX). The FAA has undertaken studies to identify PBN improvements that can be completed within three years, followed by the design phase to implement these changes, at 5 metroplex locations: Washington, D. C., North Texas, Northern California, Southern California, Houston, Atlanta, and Charlotte. Work of vari­ous kinds to advance the program is ongoing at a number of other locations at the same time. (See Figure 36-2.) Some 21 metroplex areas have been designated in this program,2 adding 5 per year for studies and design work. These efforts include both airspace and airport surface improvements and coordination.
