FAA Cracks Down on Erroneous ADS-B Codes

The FAA is targeting non-performing ADS-B equipment that transmits incorrect flight identification codes and erroneous position reports, among other false data. FAA

Key Takeaways:

  • The FAA is cracking down on "non-performing equipment" (NPE) in ADS-B systems that transmit invalid or incorrect data, such as erroneous ICAO addresses or position reports.
  • NPE aircraft are filtered from air traffic control systems and TIS-B, and the use of general ICAO codes (e.g., 000000) by multiple aircraft can lead to one disappearing from radar/ADS-B displays, creating a safety hazard.
  • The FAA has observed at least one flight per day with an incorrect ICAO address code over the last three years.
  • Pilots can verify their ADS-B equipment's proper functionality and ensure their Mode S code is correct by requesting a Public ADS-B Performance Report (PAPR) or checking the FAA database.

If you are one of many pilots who have stayed ahead of the mandate to install ADS-B-Out equipment in your airplane before January 1, 2020, you might want to make sure that the transponder codes in the system are correct. The FAA is cracking down on what is called non-performing equipment (NPE) — ADS-B equipment that transmit invalid or unassigned 24-bit ICAO addresses, incorrect flight identification codes, erroneous position reports, and other false data.
