Research On Low-Altitude Visual Corridors Capacity Based On Workload

During the "13th Five-Year Plan" period,China’s general aviation industry is developing rapidly,and the number of aircraft engaged in general aviation and the types of missions are increasing day by day,and the scope of activities is expanding,resulting in the increasing tension of China’s airspace resources,especially low-altitude airspace resources.Since most of China’s airspace is controlled airspace,it does not open up low-altitude airspace according to the spatial charicteristic,resulting in idle low-altitude airspace resources.The continuous and in-depth work of the pilot low-altitude airspace cooperative management reform in Sichuan Province has innovated the management mechanism and management mode of low-altitude airspace for China.As of 2019,the training demand of Civil Aviation Flight University of China has been increasing year by year,coupled with the successful test flight operation of Tianfu International Airport,resulting in a great compression of its training airspace resources.Based on the transit routes between the branches of the Civil Aviation Flight University of China in Sichuan Province,this paper firstly introduces the operation mode of low-altitude visual access in the pilot low-altitude airspace cooperative management reform in Sichuan Province,and also models the process of planning the transit routes of Civil Aviation Flight University of China as low-altitude visual access.Secondly,the relationship between eye movement index and workload is verified through comparative experiments,and eye movement index is selected as an important parameter to quantify the surveillance load assessment,and then K-Means cluster analysis with fused convex packet algorithm is applied to delineate areas of interest.Then,the definition of the workload of low-altitude visual corridors and its influencing factors are introduced,and the workload assessment model of out low-altitude visual corridors is proposed in combination with the eye movement index.Finally,the operational capacity of the lowaltitude visual corridors is calculated based on this workload assessment model,and the validity of this model is analyzed by comparing and verifying examples,and suggestions for capacity optimization are proposed.
