Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Classification of methods and procedures of the estimation of the fitness for work of control system of air vessel during the investigation of the aviation incidents YU.V. POPOV, I.A. UVAROV In the article the process of the investigation of aviation incident based on the reconstruction of functions of aviation transport system is shown. Numerous versions are formed on basis of the assembled data about the aviation incident. In the article the statistical data about the distribution of the versions of the reasons for aviation incidents are given. It is established on basis of statistical data that the version about the failure of control system of air vessel is advanced in 30% of cases of aviation incidents. Three problems are solved during the investigation of aviation incidents because of the failure of aviation equipment: the parameters of flight with the collision of air vessel with the obstacle are determined, the fitness for work of the aggregates of systems is determined and the reason for failure is established. Statistical data show that the greatest attention during the investigation of aviation incidents is paid to the study of control system by air vessel. Experience shows that the study of control system by air vessel during the investigation of aviation incidents has its own methodology of knowledge. In this article the classification of methods of investigation of control system by air vessel during the investigation of aviation incidents is proposed by the cluster analysis method. As a result four clusters of methods and procedures of the estimation of the fitness for work of control system by air vessel during the investigation of aviation incidents were obtained. Keywords: investigation, aviation incident, air vessel, aviation transport system, version, control system, estimation of fitness for work, cluster analysis, cluster.
