Department of Transportation Federal Aviation Administration • 14 CFR Part 91 • [Docket No.: FAA-2022-1212] AGENCY: Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Notification of changes to surveillance services. SUMMARY: This document announces termination of the Mode-S Traffic Information Service (TIS) at FAA terminal Mode-S radar sites. The FAA is replacing 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 aircraft with a properly functioning Automatic Dependent Surveillance—Broadcast (ADS-B) system. DATES: Effective June 23, 2023.

SUPPLEMENTARY INFORMATION: Executive Summary In 2018, the FAA performed an assessment of the safety 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 work 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., Aircraft Electronics Association (AEA), Aircraft Owner and Pilots Association (AOPA), Experimental Aircraft Association (EAA), and General Aviation Manufacturers Association (GAMA)). Taking into consideration the results of the FAA study and the benefits from the ADS-B In traffic services available in the NAS, the FAA determined that removal of Mode-S TIS had little to no significant adverse safety impact on the GA Community. Therefore, beginning in 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 Mode-S TIS information from FAA 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). Reception of Mode-S TIS information was not a functionality that was required for Mode-S transponders. To this day, a very limited set of transponders are known to be capable of receiving and processing Mode-S TIS information from FAA terminal radars. In May 2010, the FAA published 14 CFR 91.225 and 91.227, requ…
