As the countdown continues to the Dec. 31, 2019, deadline for ADS-B Out installation, the pace of updates is expected to increase significantly and the agency is concerned about shops rushing to complete the required work.
FAA Warns of ADS-B False Alerts
Key Takeaways:
- The FAA has issued a safety alert regarding improper ADS-B Out ground testing procedures, as the December 31, 2019 installation deadline approaches and shops may rush installations.
- Faulty ground tests have erroneously transmitted simulated altitude information, creating false airborne targets that triggered TCAS alerts and caused significant air traffic control (ATC) delays.
- The agency recommends ensuring transmission lines are correctly attached to test equipment or using antenna shielding during ground tests to prevent signal interference, and sometimes notifying ATC.
