## Abstract

This action announces changes to the following surveillance and broadcast services ("surveillance services") after January 1, 2020: Automatic Dependent Surveillance--Broadcast (ADS-B); Traffic Information Service--Broadcast (TIS-B); Automatic Dependent Surveillance--Rebroadcast (ADS-R); and Automatic Dependent Surveillance--Same Link Rebroadcast (ADS-SLR). These service changes will affect aircraft equipped with older ADS-B avionics that do not meet the requirements of 14 CFR 91.225. The service changes will primarily affect aircraft operating in specific airspace areas, though a few service changes will affect aircraft operating throughout the National Airspace System (NAS).
