| As the hub of air transportation, Air Traffic Control (ATC) system assumes the important responsibility of protecting air traffic safety. However, several experiences of emergency support work have exposed following problems: emergency equipment configuration is not complete, emergency security planning is not perfect,maintenance work is insufficient, and so on. Through the ATC equipment performance and system effectiveness evaluation, equipment capabilities and system effectiveness conditions can be obtained. Then, security planning of facilities can be carried out.In this paper, models of key ATC facilities, including VHF station, VOR/DME station, NDB station, PSR and SSR, were established according to the radio wave propagation theory, electrical and electronic theory, and radar detection theory, etc. Then, graphical visualization of facility performance coverage was realized, using MATLAB programming and MapInfo software. Chengdu Terminal Control Center was taken as an example to validate and analyse the models. In the following, principles and methods of reliability engineering were adopted to assess reliability of ATC system. Then, reliability assessments for ATC communication subsystem, navigation subsystem and surveillance system of Chengdu Terminal Control Center were conducted according to operation security and maintenance practices. On the basis of performance and reliability assessment result, ADC model, which was widely used in military field, was introduced into ATC system. Considering ATC system’s characteristics, the model was modified, and an intergrated evaluation method called ADC-AAHP was proposed, which was applied into system effectiveness evaluation of Chengdu Terminal Control Center. According to the result of system effectiveness, principles and methods of Business Continuity Planning (BCP) were introduced to guide ATC facility security planning. Then, facility maintenance planning was studied, giving spare parts planning model and method, and regular maintenance work of key facilities was listed as well. Finally, research work was briefly summarized, and further research was discussed. |
