FAA Warns of ADS-B False Alerts
Key Takeaways:
- The FAA has issued a safety alert due to concerns about rushed ADS-B Out installations ahead of the December 31, 2019 deadline.
- Improper ground testing of new ADS-B equipment has resulted in erroneous transmission of simulated altitude data from test aircraft.
- These false signals have created airborne targets that triggered TCAS II resolution advisories for in-flight aircraft and caused significant air traffic control delays.
- The FAA recommends repair stations ensure proper transmission line attachment, use antenna shielding, and consider notifying ATC during ADS-B equipment testing to prevent interference.
