Abstract: Currently,no administrative procedure is in place for the use of unmanned aerial vehicles (UAVs), which poses a serious threat to aviation security.In order to ensure the safety of using UAVs,it is important to supervise the activities of UAVs through a flight plan management system.Hereby such a system is proposed in this paper.Based on the analysis of basic components,expression model and life cycle of a flight plan,this management system consists of three modules:planning processing,planning verification,and planning execution.The module of planning processing re-ports and audits flight plans of UAVs;the module of planning verification verifies the performance of flight plans via the data of airspace,geographic,and weather;the module of planning execution monitors the progress of flight plans and the flight states.A demonstration run shows that the system can effectively manage flight plans of UAVs,simulate corre-sponding flying tracks and execute real-time monitoring.
