The development of Urban Air Mobility (UAM) requires that aircraft must stay safely separated from each other. The potential density of the UAM airspace necessitates resolving encounters with more than two aircraft. This paper focuses on resolving multi-aircraft encounters using NASA’s Detect and AvoID Alerting Logic for Unmanned Systems (DAIDALUS) software by testing different scenarios that challenge the current rules of the road for the UAM environment. Results from these scenarios are presented and analyzed in order to give guidance for the refinement of the software, as well as find best practices for resolving multi-aircraft conflicts in a dense environment. Finally, recommendations are presented in order to ensure safe operations in the UAM environment.
