Abstract: In the research on the operation and construction of the smart flight zone,it is currently focused on the digital twin service application module.There are still problems of lack of interaction between the digital model and the physical space,and lack of application of functions.In view of the existing problems,a four layer basic architecture of flight zone operation digital twin was built relied on the physically mapping and simulation of digital twin technology to multi-elements of flight zone operation.Through the real-time data transmission,the virtual and real mapping and status update between physical space and objects,digital twin models and virtual targets were realized.Combined with the data simulation iteration in the twin domain,the real-time decision-making in the physical domain was realized,which provided pilots and controllers with real-time aircraft status feedback,command risk assessment and other services.Within this framework,the feasibility and necessity of five key technologies were analyzed,and the three-dimensional spatial structure of flight zone operation was modeled through terraexplorer,Java and other tools,and the simulation and visualization of surface risk assessment based on aircraft operation instructions were carried out.The maturity of the current digital twin technology of flight zone operation was evaluated,and the feasibility of building a digital twin operation flight zone was verified.
