The paper deals with the problem of synthesis and analysis of sequential procedure for identifying the deterioration of the technical condition of radio equipment. Radio electronic equipment plays a leading role in ensuring the safety and regularity of flights. The operation system includes equipment, technological processes, personnel, regulatory documentation, resources, and determines the reliability of the equipment. Decision-making in operation systems is based on the results of statistical data processing. The initial data for processing are reliability indicators and determining parameters of radio equipment. In general case, the technical condition of the equipment during operation may deteriorate. Detection of changes in the technical condition can be considered as a task of analyzing the changepoint. In this article, the synthesis of a sequential detection procedure with a previously unknown sample size was performed. During the synthesis, analytical equations for decision thresholds were found. The analysis of the sequential procedure was performed analytically and using statistical simulation. Analytical equations were found for the mathematical expectation of the duration of decision-making and for the operational characteristic. The research results can be used during the design and modernization of operation systems of radio equipment in terms of synthesis of operational data processing procedures.
