Abstract: In recent years, with rapid development of civil aviation and adjustment of transport structure, the number and throughput of small and medium-sized airports in China are also growing fast under the guidance of the national strategy, however, which can not match with safety, operation guarantee resources and security capacity, resulting in a high incidence of unsafe incidents. Considering that some problems existing currently in small and medium-sized airports, such as insufficient supervision, large differences in management modes, excess budget cost of operating, we should focus on scientific division standard, implementation of differential management, innovation of supervision method, reduce pressure reasonably, and ensure the sustainable and safe development of small and medium-sized airports from top-level design.
