A Holistic Design and Simulation of Advanced UTM Services for Urban Air Mobility

This paper presents a modular suite of collaborative Unmanned Aircraft System Traffic Management (UTM) services designed to enhance urban airspace operations. The framework integrates various pre-flight and in-flight services within a semi-autonomous simulation environment that emulates UTM service provision for urban airspace operations. It adopts a holistic approach that fosters intelligent algorithm design, robust serviceability, and strong collaboration among different services, enabling comprehensive simulation and assessment of their automated interactions and overall system performance. Building on the Air Mobility Urban - Large Experimental Demonstrations (AMU-LED) project, this study advances UTM service maturity with over 1,600 simulation flight hours across three traffic density levels within a synthetic urban airspace. The analyses assess the impact of specific UTM services on Key Performance Areas such as safety, path efficiency, and operational workload in a 115 NM${}^{2}$airspace, accommodating up to 150 operations, including 40 simultaneous operations.
