    Federal Register Policy on Definition of Aeronautical Activities

    ★ 32
    The FAA proposed updating its definition of 'aeronautical activity' to include unmanned aircraft systems (UAS), advanced air mobility (AAM), and commercial space launch operations, meaning federally obligated airports must provide non-discriminatory access to these emerging technologies. The policy clarifies that while these new operations qualify for airport access, the FAA retains authority to assess safety risks and set conditions for accommodating them. Recreational UAS, model aircraft, and model rockets are explicitly excluded from the updated definition.
