Dynamic Redundancy in Communication Network of Air Traffic Management System

In the paper the channel reliability of communication network with common set of standby radio stations for real conditions of Air Traffic Management (ATM) is discussed. ATM systems represent essential infrastructure that is critical for flight safety and communication is a key element in the present ATM system. As additional method of improving the reliability of the ATM communication network a dynamic management of backup modes with two-stage mode of redundant elements is proposed. Mathematical model of the channel reliability is developed. Comparative analysis of redundancy effectiveness for developed and used structure of ATM communication network is performed.
