The Federal Aviation Administration (FAA), in a continuing effort to improve the safety, efficiency, and capacity of the National Airspace System, has been working with industry to develop and demonstrate new surveillance technologies such as Automatic Dependent Surveillance—Broadcast (ADS-B) through such efforts as Safe Flight 21 program, the Capstone program (currently being used in Alaska), and other United States National Airspace System (NAS) programs. To assist the aviation community in obtaining FAA approval of related systems and equipment needed to support these services, the Flight Standards and Aircraft Certification Services developed the proposed AC.
