Establish High Availability Of Air Traffic Control System

With increasing air traffic flow, air traffic control system(ATCS) of CAAC assuring air safety meets new challenge. Air traffic is more and more congestion without air space enlargement. How to prevent conflict between aircrafts, aircraft and grounding obstructions and ensure perfect air traffic is an important mission of CAAC, and it is also main task of ATC system.The article analyses high availability technology, describes design philosophy of the high availability system and high availability design of ATC system, including system architecture, main functions and reliability etc. Finally, it elaborates the system could implement troubleshooting via some methods and rapid self-repairing or trouble isolation and lockout, and make the system into normal operation state through new setup. So the article emphasis how to realize high availability of ATC system base on design and implementation of trouble processing and technology.
