Safety and Security Concerns of the Urbam Air Mobility. As Urban Air Mobility (UAM) systems take flight, ensuring their safety and security becomes decisive for public acceptance. The research explores critical aspects of UAM SoS, shedding light on safety perspectives, particularly the challenge of Situation Awareness in both urban ground and airspace. Addressing security concerns, encompassing cyber and physical threats, is equally crucial for a safe UAM operation. Moreover, establishing a robust safety culture is explored as an organizational element to facilitate learning in this novel domain. The contribution includes a holistic approach and introduces insights using the Unified Architecture Framework (UAF). Modeling SoS views with UAF proves valuable for system engineers, providing a powerful tool to represent complex operations and fostering applied systems thinking for a safer and secure urban aviation future.
