Abstract:With the vigorous development of my country's low-altitude economy, low-altitude safety risks have become increasingly prominent and have become an important factor restricting its further development. This paper focuses on the safety management of low-altitude flight, aiming to build an effective system collaborative management mechanism to promote the safe and healthy development of low-altitude airspace. First, the connotation and characteristics of low-altitude safety are analyzed, and it is clarified that it involves multi-dimensional elements such as aircraft operation, personnel operation, environmental conditions and management measures; secondly, based on the four dimensions of man, machine, environment and management, the decision laboratory analysis (DEMATEL) method is used to quantitatively identify 11 key risk factors such as regulatory means, geographical environment, and meteorological conditions, revealing the core driving role of human factors and management factors; finally, a "five-coordination" management mechanism including governance coordination, environmental coordination, normative coordination, security coordination and man-machine coordination is proposed, and the systematic goals of risk prevention and control, regulatory efficiency improvement and social cognition improvement are achieved through multi-dimensional linkage. The research results provide theoretical support and practical paths for low-altitude safety management, and help promote the benign interaction between low-altitude industrial economy and safety management.
