Abstract
Proliferation of new classes of airspace participants, including uncrewed and advanced aerial mobility vehicles, necessitates the development and deployment of novel airspace management solutions, such as the Unmanned Traffic Management (UTM) system and the Provider of Services to UAM (PSU) Network. The efficacy of such systems has been demonstrated on multiple occasions via real-world deployments in limited test environments, however exploration of system behavior under stressing conditions requires the development of appropriate modeling and simulation (M&S) environments. Autonomy Networks for Advanced Mobility at Lincoln Laboratory (ANAMLL) is a virtual Systems Integration Laboratory (SIL) designed to host federated autonomy networks, such as a UTM or PSU Network, and to enable test and validation at scales not available in real-world deployments. As an example of ANAMLL's utility, we explore the performance of a representative UTM network during a stressing demand scenario. In a close examination of the demand scenario, ANAMLL demonstrates a UTM system demand point at which in-flight replanning can no longer be accomplished within an allowable time window. In a second analysis of the same scenario, ANAMLL demonstrates the impact of network connectivity performance on end-user airspace access.
