About 20% of all ADS-B out systems are installed incorrectly. To help owners identify incorrect installations, starting January 2, 2018, the FAA filter these aircraft from the system. The filter will catch ADS–B equipped aircraft that are 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). “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 reasonably result in erroneous ADS–B information affecting the safety of ATC services.
The FAA intends when possible, to provide individual notice to owners/operators before implementing the filter. This notification would describe the reason for applying the filter and steps that must be taken before an aircraft can be removed from the filter. If an aircraft owner/operator does not respond to an FAA notice of finding regarding an ADS–B avionics issue, the agency might subject that aircraft to the filter without further notice. Owners and operators can identify the ICAO address filtering status of their aircraft by requesting a Public ADS-B Performance Reports (PAPR). This is available for aircraft operations within FAA ADS-B coverage areas. To use the tool, aircraft owners or operators simply input some basic information about a particular aircraft, including tail number, ADS-B equipment make/model and flight date. The FAA then sends the PAPR to the user’s provided email address, typically within 30 minutes. Users should understand that operations close to ground level or near the fringes of ADS-B coverage areas might not yield accurate results.
If the report includes an error message, the aircraft owner or operator can use that information to have the problem rectified by their avionics shop.
All aircraft operators with ADS-B equipment installed in their aircraft should take a few moments to use the PAPR tool. It’s critical that aircraft owners and operators verify the health of their ADS-B equipment and ensure the FAA is receiving accurate data.
