Methods of Service Life Determining for Aviation Radio Equipment

The paper focuses on the improvement of operational processes of aviation radio equipment. Communication, navigation and surveillance devices are main means to provide the function of air traffic control. The serviceable functioning of radio equipment has significant influence on aviation safety and aircraft availability. The main process during equipment operation is intended use. During this process fulfillment, changes of technical condition are possible. In addition, the probable deterioration of technical condition can decrease the service life of equipment. For timely decision-making about radio equipment decommission and disposal, it is necessary to implement procedures of online monitoring for reliability parameters and remaining useful life estimation for corresponding devices. This paper concentrates on comparative analysis of methods of service life determining during operation of radio equipment to make correct decision on possibility of further operation or decommission.
