Since January 2, the FAA has implemented a filter for certain ADS–B-equipped aircraft found to be broadcasting erroneous or improper information that could affect the safe provision of air traffic services. “Any aircraft subject to the filter will not have its ADS–B information sent to an ATC facility nor will the aircraft be a client for traffic information services [TIS-B],” the agency said. “Affected aircraft will continue to receive ATC services within radar coverage using secondary radar information.”

For those aircraft transmitting erroneous information, the Public ADS-B Performance Report (PAPR) will search for the flight ID matching the entered U.S. registry number if it cannot locate the corresponding mode-S code. The FAA could also use the filter for aircraft that are discovered to have other issues, including transmitting non-compliant codes, that could result in erroneous ADS–B information affecting safety of ATC services.
