This legislation establishes new requirements and limitations concerning the use of automatic dependent surveillance-broadcast (ADS-B) data. It explicitly prohibits any person, including government agencies, from using ADS-B data to identify aircraft for the purpose of assessing fees or imposing charges. Furthermore, air traffic controllers are restricted to using this data primarily for tracking aircraft, enhancing air traffic safety and efficiency, or for purposes approved by the Secretary of Transportation. The bill also expands existing limitations on the use of ADS-B data in investigations, extending the prohibition to Federal, State, local, territorial, and Tribal officials. A second key provision addresses the imposition of fees on general aviation aircraft by public-use airports. Before implementing any landing or take-off fees, airport owners or operators must publicly disclose information regarding efforts to reduce non-airside expenses, alternative revenue generation, and detailed plans for airside safety projects. This disclosure must also include an assessment of the fees' impact on the health of general aviation. Importantly, any revenues collected from these fees are strictly limited to funding **airside safety projects**, with the Federal Aviation Administration authorized to establish necessary regulations and reporting requirements.
