The Southern California Metroplex Project is a comprehensive proposal to improve the flow of air traffic into and out of Southern California by making the airspace safer and more efficient. The project proposes to replace dozens of existing conventional air traffic procedures with new satellite-based procedures, which are a key component of the FAA’s Next Generation Air Transportation System (NextGen). Metroplex initiatives are completed, under way, or planned in more than a dozen metropolitan areas across the country.
According to the FAA, some people will experience slight noise decreases, some will see no changes, and some will experience small noise increases. The FAA plans to begin working immediately toward phasing in use of the procedures, starting in November 2016 and continuing through April 2017.
