Аннотация:The article considers the classification of airborne vehicles in the automated air traffic control system, which is essential for improving the level ofair traffic safety. Proposed is a new method of airborne vehicles’ classificationwhich differs from the existing ones, as it is distinguished by integrated data processing from heterogeneous sources, formalizing the characteristics of airbornevehicles based on binary relationships and production models, the hierarchicalstructure of airborne vehicles’ classification and the structural features of the singleton knowledge base. This article is the sequel to the earlier articles written bythe authors on air navigation issues.
