Understanding BNATCS
ATCA is here to help you learn and navigate as the BNATCS journey evolves
The Brand New Air Traffic Control System (BNATCS) is a comprehensive initiative led by the Federal Aviation Administration (FAA) and the U.S. Department of Transportation (DOT) to modernize the National Airspace System (NAS). The program aims to replace aging infrastructure with a modern, integrated air traffic control system that enhances safety, improves efficiency, increases capacity, and prepares the nation's airspace for future aviation technologies.
BNATCS encompasses a wide range of modernization efforts, including communications, surveillance, automation, digital infrastructure, facilities, cybersecurity, and workforce development. Together, these investments will create a more resilient and connected air traffic management system capable of supporting the evolving needs of commercial aviation, general aviation, military operations, uncrewed aircraft systems (UAS), Advanced Air Mobility (AAM), and commercial space operations.
This Knowledge Center provides a centralized resource for understanding BNATCS and its ongoing development. Drawing from publicly available information from the FAA, DOT, Congress, and other authoritative sources, it offers an organized, easy-to-navigate overview of the program, its technologies, policy developments, implementation progress, and industry impacts.

BNATCS Capabilities
Below are the capabilities identified by the FAA and are covered under that initial $12.5B funding approved by Congress as a down-payment. These capabilities mainly cover the modernization of technologies and infrastructure. However, an additional $20B is needed fully modernize AND transform the NAS.
Internal ATCA Note: Each of the below boxes could link to a separate page that provides a deep-dive into the BNATCS-realted info that falls under that category.
Communications(Telecom, Radios, Voice Switches) Technologies that enable controllers, pilots, and other aviation personnel to exchange critical operational information. |
Surveillance(Radars, ADS-B) Technologies that enable aircraft & vehicle positions to be accurately detected, identified, and tracked. |
Automation(FMDS, TFDM, controller display systems) Technologies that enable flight data to be collected, processed, and presented for flight management & operational efficiency. |
Facilities(ARTCCs, TRACONs) Buildings, equipment, and supporting infrastructure required for air traffic operations. |
Alaska(Weather Systems, MARS) Alaska possesses unique operational, geographic, and environmental challenges that requires special focus. |
Other(Programs & Tech) Encompasses supporting programs and technologies that complement and strengthen the modernization of the National Airspace System. |
