For each scenario, aviation-compatible TOL procedures are defined, including lateral and vertical profiles, separation logic, and vertiport protection volumes. In parallel, phasedependent Communication, Navigation, and Surveillance (CNS) requirements are analyzed to characterize supporting infrastructure and performance needs. The procedures are first refined and optimized and then evaluated by simulation under different traffic conditions to assess feasibility, robustness, and scalability, with input from air traffic management (ATM) experts. Preliminary results indicate that a small set of structured procedures can support diverse UAM operations. Further analysis of CNS requirements is ongoing to complete evaluation and validation.enSurveillanceCommunicationNavigationTake-off and Landing (TOL) proceduresUrban Air MobilityTechnology::629: Other Branches::629.1: AviationConference Paper10.1109/SysCon66367.2026.11503488
