Abstract/Description
In Singapore's high-density urban airspace, integrating Unmanned Aircraft Systems (UAS) and Advanced Air Mobility (AAM) into NextGen Trajectory-Based Operations (TBO) faces a significant scalability challenge due to reliance on centralized, legacy Command and Control (C2C) architectures. The problem lies in the latency and inefficiency inherent to centralized Air Traffic Management (ATM) systems when managing heterogeneous, low-altitude traffic. This is particularly true during non-nominal events, such as unpowered ballistic descents. Currently, these events necessitate disruptive airspace segregation, such as Temporary Flight Restrictions (TFRs). This paper presents a conceptual and architectural framework for federated UAS Traffic Management (UTM), utilizing intent sharing and 4D dynamic terminal manoeuvring zones to optimize conflict resolution. It also outlines validation pathways for future empirical studies. The proposed framework enables safe, high-density autonomous operations in urban environments without degrading the efficiency of the global TBO network, shifting from tactical ATM micro-management to a resilient, protocol-based trajectory negotiation system.
