Facilitating Opportunities for Advanced Air Mobility

In this document, the Federal Communications Commission (FCC or Commission) proposes and seeks comment on changes to the rules that govern the operations of three distinct bands of spectrum, modernizing rules to facilitate opportunities for Advanced Air Mobility (AAM) and Uncrewed Aerial Systems (UAS). First, the Notice of Proposed Rulemaking (NPRM) proposes and seeks comment on opening up the 450 MHz band to aeronautical command and control operations; allowing for a single, nationwide license in the band; and adopting flexible licensing, operating, and technical rules that will facilitate robust use of the band at a range of altitudes while minimizing interference to neighboring operations. It also proposes expanding radiolocation operations in the 24.45-24.65 GHz band for uncrewed aircraft system detection operations. Finally, the NPRM proposes to modernize the Commission's legacy power rules for Commercial Aviation Air-Ground Systems in the 849-851 and 894-896 MHz band, which is used for in-flight connectivity.
