“…This process shall enable system designers to systematically define, assess, design, implement, verify, and validate the system's safety and security requirements through the system design phases and operational life cycle. The RA2 shall establish resilience [4] by providing prevention, detection, response and recovery capabilities to ensure security and functional safety (fail-operational, fail-safe and fault-tolerant) [5], [11], [12] of UAM missions. This paper extends [9] and complements previously published research works [12], [13], [14], [15].…”
