Under conditions of intense competition, the creation of new products and their promotion to the market requires marketing support. The central element of marketing innovation management is marketing positioning. In contrast to the methodological aspect, there is almost no procedural component of positioning in scientific works and publications. Moreover, due attention is not paid to the issues of market segmentation and the allocation of the competitive advantage of such high-tech products as civil aircraft. This determines the relevance of the task of developing a procedure for marketing positioning within the framework of managing the product offer of the aircraft industry enterprises. From the standpoint of a systematic approach, the necessity of studying the adjacent air transportation market is reasonable, as well as the analysis of the correlation of its segmentation with the allocation of target segments of the aircraft market. When conducting a competitive analysis, we propose to consider the market position not only of certain types of civil aircraft, but also of aircraft families. Modeling marketing management shows the role of positioning in the processes of creating, manufacturing and operating aircraft. A distinctive feature of the procedure is the proposed stage of evaluating the effectiveness of the selected product position implementation, which allows us to analyze the feasibility of marketing decisions throughout the product life cycle. Special attention is paid to the issues of information support. The research results presented here reflect the specifics of the marketing activities of aviation industry enterprises and contribute to the development of the conceptual foundations of industrial marketing.
