ABSTRACT
UTM has represented a major step integrating unmanned aircraft operations into the NAS, as well as a turning point in aviation history. UTM enables the automation needed to handle the new services and predicted volume of unmanned flights. The scope and characterization of possible UTM services remain in play, but may include, in part, registration, UAS remote ID, discovery, strategic coordination, constraint management and constraint ingestion, and associated security services. Important UTM features include interoperability, scalability, automation, and, of course, safety. Since UTM is infeasible without standards. Governance of UTM is in development. UTM will eventually support more than very low-level altitude (VLL) airspace operations: air taxis, stratospheric, and even space traffic management (STM) operations. What is being learned in UTM will inform and enable Advanced Air Mobility (AAM). Nearly every dimension of aviation infrastructure is in the crosshairs of UTM and fair game for scrutiny, imagination, innovation, and reformulation. The skies will be forever changed.
