Application of control transfer technology between automated air traffic control systems based on flight data interaction

In the face of the increasing number of flights, the current AIDC operation mode is difficult to guarantee the success rate when managing a large number of flight handover management based on height and complex airway handover management. In 2018, CAAC released the research and Verification Technology Project Plan for the control transfer Technology between automated air traffic control systems based on flight data interaction, aiming to improve China's control transfer data communication technology. This paper expounds the project construction background, construction content and technical innovation in detail. The project results solves the problem of vertical transfer between automation systems that cannot be satisfied by AIDC protocol, and realizes the control transfer between heterogeneous systems of different manufacturers, which is helpful to further improve the localization level.
