Automatic Dependent Surveillance-Broadcast (ADS-B) Out prohibition

This regulation prohibits drone operators from flying with ADS-B Out equipment actively transmitting unless the FAA specifically authorizes it. ADS-B Out is technology that broadcasts an aircraft's position, altitude, and other data to air traffic control and nearby aircraft.

The rule exists because drones typically operate at low altitudes where ADS-B transmissions could create confusion or clutter the system designed primarily for manned aircraft. Broadcasting false or misleading position data could interfere with the safety benefits ADS-B provides to the National Airspace System.

In practice, this means if your drone has ADS-B Out capability built in, you must ensure it's turned off or in receive-only mode during flight. You can only operate with it transmitting if you've obtained specific authorization from the FAA. This is separate from ADS-B *In* (receiving traffic information), which is not restricted under Part 107.
