UTM concept demonstrations in Fukushima; overview of demonstration and lesson learnt for operation of multiple UAS in the same airspace

Japan Unmanned System Traffic & Radio Management Consortium conducted a large flight demonstration and made about 120 flights of 20 small Unmanned Aerial Systems (UAS), which includes one simulated aircraft, in October 2017. All the flights were under a traffic management, and all the operators submitted a flight plan, reserved an airspace and followed the navigation of the controller. This paper describes the overview of a concept of UAS traffic management (UTM) and the demonstration, and discusses the feasibility and challenges of the UTM concept.
