Department of Transportation Federal Aviation Administration • 14 CFR Part 91 • [Docket No.: FAA-2022-1212] AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Notification of changes to Surveillance Services. SUMMARY: This action announces termination of the Mode-S Traffic Information Service (TIS) at 104 terminal Mode-S radar sites. The FAA is replacing these legacy terminal Mode-S radars via the Mode-S Beacon Replacement System (MSBRS) program, or may remove legacy terminal Mode-S radars as part of other ongoing activities. As each legacy terminal Mode-S Radar is replaced or removed, the FAA will no longer provide Mode-S TIS to capable transponders from that location. This change does not affect existing Traffic Information Service—Broadcast (TIS-B), Automatic Dependent Surveillance—Rebroadcast (ADS-R), or Automatic Dependent Surveillance—Same Link Rebroadcast (ADS-SLR) services currently provided to properly ADS-B equipped aircraft. DATES: September 22, 2022. FOR FURTHER INFORMATION CONTACT: For technical questions concerning this action, contact: Michael Freie, Technical Advisor, Surveillance Services, AJM-4, Air Traffic Organization, Federal Aviation Administration, 600 Independence Avenue SW, Washington, DC 20597; telephone: 202-528-2337; email: michael.freie@faa.gov. SUPPLEMENTARY INFORMATION: Executive Summary In 2018, the FAA commissioned a study to assess the safety and economic impacts on general aviation owners and operators (from here on referred to as “the GA Community”) from the termination of Mode-S Traffic Information Service (TIS). The purpose of this study was to communicate information on the removal of Mode-S TIS from the National Airspace System (NAS) through user outreach and engaging with non-governmental organizations ( e.g., AEA, AOPA, EAA, and GAMA). The results of the study confirmed that removal of Mode-S TIS has no significant adverse safety or economic impacts on the GA Community. Therefore, beginning in ( printed page 57819) 2024, Mode-S TIS will terminate at each radar location as current Mode-S radars are replaced by the Mode-S Beacon Replacement System (MSBRS) program, or as legacy terminal Mode-S radars are removed as part of other ongoing activities. The GA Community should no longer rely on reception of TIS information from Mode-S capable radars. I. Background In 2000, FAA implemented Mode-S Traffic Information System (TIS) via Mode-S radar data-link functionality. Mode-S TIS has also been referred to informally as TIS-A by some in industry. Mode-S TIS was implemented by FAA in response to an NTSB recommendation suggesting improvement of situational awareness information for the general aviation (GA) community not equipped with a traffic alert and collision avoidance system (TCAS). In May 2010, the FAA published 14 CFR 91.225 and 91.227, requiring aircraft to be equipped with Automatic Dependent Surveillance—Broadcast (ADS-B) Out equipment by 1 January 2020 in order to operate in certain U.S. airspace. ADS-B was identified as the backbone for the future of the FAA's Next Generation (NextGen) programs. From 2010 through 2020, the FAA funded deployment of approximately 700 ADS-B radio stations across the U.S. to provide improved surveillance coverage across the NAS. Along with improving surveillance coverage, the FAA implemented functionality into ADS-B r…
