FAA Issues ADS-B Advisory Circular

New guidance spells out pilots’ ADS-B responsibilities.

The FAA has issued an Advisory Circular detailing pilot operational requirements when flying with automatic dependent surveillance-broadcast (ADS-B) technology for compliance with FAR 91.225 and 91.227.

The new regulations require aircraft operating in designated classes of airspace (pretty much anywhere you need a transponder now) to be equipped with ADS-B Out starting on Jan. 1, 2020. Advisory Circular 90-114 contains guidance on compliance with the new rules including an overview of the ADS-B system, general operating procedures, and performance and training requirements.

Little appears to have changed from what the FAA has been saying all along about ADS-B compliance, but spells out some specifics. For example, the FAA noted that your ADS-B transmitter must be turned on at all times, including while operating on the airport surface. And when filing a flight plan, the FAA says pilots flying with ADS-B equipment should include the note “RMK/ADSB.”

The FAA notes that current transponder requirements are unaffected by the ADS-B rule. The Jan. 20, 2020, mandate includes ADS-B OUT technology only, and not ADS-B IN, which can be used to receive traffic information and free FAA services including downlink weather data and graphical TFR information.
