Next Generation Air Transportation System (NextGen)

The Next Generation Air Transportation System (NextGen) is a large-scale FAA initiative to modernize the U.S. National Airspace System (NAS).

Through NextGen, the FAA has modernized air traffic infrastructure in communications, navigation, surveillance, automation, and information management with the aim of increasing the safety, efficiency, capacity, predictability, flexibility, and resiliency of American aviation. NextGen’s scope includes airport infrastructure improvements, new air traffic technologies and procedures, and safety and security enhancements.

NextGen improvements also help to reduce aviation’s effects on the environment. The FAA supports programs to facilitate sustainable aviation fuel uptake as well as aircraft and engines that lower fuel consumption and emissions.

We engage with the public and share noteworthy practices with the aviation community to accelerate the adoption of innovative technologies. The FAA and its partners have implemented major new technologies and capabilities, which are leading to a new way of managing air traffic known as Trajectory Based Operations (TBO).

Our modernization initiative enables a more flexible — yet robust and resilient — aerospace infrastructure that ensures the safe introduction of non-traditional users into aviation, such as commercial space transportation and advanced air mobility operations.

Through research and collaboration, NextGen is defining new standards and further advancing our global leadership in aviation. The FAA fosters international cooperation in evolving enhanced aviation technologies that improve airspace system safety and mobility.

Explore the past, present, and future of NextGen.


Background

The United States has the world’s busiest and most complex airspace system. Spurred by forecasts for future air traffic demand, the FAA started NextGen to make flying safer, more efficient, and more predictable.


NextGen Today

NextGen capabilities are active and expanding at locations across the nation.


Future NAS

The FAA is looking to further improve NAS operations through TBO and introducing a vision for an information-centered system built for diverse operations.


Performance Reporting and Benefits

NextGen improvements have realized benefits that we have measured by year and type. Benefits will accumulate over time as NextGen pursues its integral contribution to the U.S. airspace, economy, and flying public.
