The Development of Low Altitude Airspace Safety Management Driven by New Quality Productivity: A Low Altitude Airspace Safety Management System (LASMS)Conceptual Framework of Urban Air Mobility

Safety is the prerequisite and baseline for the development of the low-altitude economy, and the challeng-es of safety supervision in future low-altitude airspace operations are receiving increasing attention. Addressing the difficulties faced in urban low-altitude airspace safety management, such as high airspace complexity, a wide vari-ety of aircraft types, high airspace usage density, numerous cybersecurity and data privacy risks, complex system in-tegration and interoperability, and substantial differences in laws, regulations, and standards. This paper considers the evolving trend in aviation safety management systems (SMS), which is shifting from single to diversified super-visory targets and from post-event management to real-time management. It proposes a conceptual framework for an urban low-altitude safety management system (LASMS), encompassing operational roles and structures for low-altitude airspace, safety performance indicators for urban air mobility (UAM), identification of low-altitude risk sources, risk monitoring, risk assessment, and risk mitigation. The core of LASMS is safety risk manage-ment, which emphasizes the identification, monitoring, assessment, and mitigation of risks to achieve near-real-time safety supervision of low-altitude aircraft throughout pre-flight, in-flight, and post-flight phases.In terms of manage-ment approaches and operational models, LASMS integrates multi-domain collaboration, distributed architec-tures, digital monitoring, and mitigation mechanisms to meet the rapid response requirements of future low-altitude operations. It enhances autonomy and automation, strengthens proactive safety control before and after flights, and ensures near-real-time safety management during flights. The discussion highlights key directions for the develop-ment of LASMS, driven by New Quality Productivity through technological innovation, alongside advancements in aviation safety management and operational models. The introduction of LASMS offers new perspectives and meth-odologies for low-altitude safety regulation, supporting the safe, efficient, and sustainable development of low-alti-tude airspace in the future.
