The book introduces Unmanned Aircraft Systems Traffic Management and how it integrates unmanned aircraft operations into a national airspace system for innovative, viable new services. Exploring possible UTM services, registration, flight planning, discovery, strategic coordination (including strategic conflict detection and conformance monitoring), the book considers the boundaries of UTM and advancing surveillance technologies. It also presents leading, relevant standards development organizations (SDOs) and their work product. The book is an essential, in-depth annotated resource for developers, operators, policy makers, researchers, and academics engaged in unmanned systems, transportation management, and the future of aviation.
