Abstract:

With the continuous emergence of new scenarios and technologies in the low-altitude field, the effectiveness of
previous experience with airworthiness standards for traditional aircraft configuration has significantly diminished. Thus, it is urgent to establish an airworthiness standard system that meets the development needs of low altitude aircraft in the future. This paper systematically reviewed the current status and future trends of airworthiness standards for low-altitude equipment both domestically and internationally, and detailedly analyzed the development history and current situation of safety technologies in the aviation field. On this basis, a new airworthiness standard system framework for low-altitude equipment was proposed, with features of system safety leadership, object type independence, safety effect-based regulations, and multiple compliance pathways. This framework helps to address issues such as low-altitude new scenarios, new technologies, their complexity, diversity,
and rapid evolution. It provides guidance and framework suggestions for the construction of low-altitude equipment airworthiness standard system, and offers strong support for implementing China's approach to next-generation international airworthiness standards.
