China Air Traffic Management Automation Systems Flying Telegraph Automation In Processing

Flight data process provides real-time, exact flight plan information for controller inthe air traffic control automatic system, and it is convenient to controller's work. Specially,Civil messages is the data source of flight data process. With the application of computertechologe and database technology, automatically recognizing and pasing messages toupdate flight plan base, the automatization of flight data process is achieved. In the thesis,the importance technology of flight data process automatically is studied. They are include:1. recognizing an processing Message automaticallyThe flight messages, which are the system receive, may have various errors that can'tbe processed and make a impact on flight data process. In the ATC SystemⅢof CAAC,With the application of Knowledge Base, the messages is processed properly, and ensureautomatically process of flight plan.2. Flight data process of messageTher are several different status in the life cycle of flight plan. When the systemprocess messages, according to the flight data in the messages, system controls the statusconversion of flight plan, and trigger coreesponding process of flight plan. In the ATCSystemⅢof CAAC, system automatically control status conversion of flight plan, manageflight data.3. Coordinate/Handover process of flight dataWhen the aircraft overfly the boundary of two air area, controllers have to handoverthe control duty to next area. By receiving and sending civil messages for coordination orhandover, the ATC systemⅢof CAAC implements flight data handover automatically,and needn't manual telephone's handover. In the ATC SystemⅢof CAAC, theapplication of civil message implement the automatical handover of aircraft control's duty.
