The study of the aircraft functional appearance design

Abstract The paper investigated the technical specification as the main document describing the major functions performed by the aircraft. The functional appearance of the on-board equipment complex is revealed in the first approximation. A range of tasks related only to solving problems of navigation and aircraft control is highlighted. The possibility of decomposition of functions depending on their degree of complexity is presented. The process of selecting existing systems to perform the required functions is investigated. The possibility of automating the process of designing a functional appearance based on existing systems is described. The system selection process has been formalized to enable the use of computer-aided design systems in order to shorten the design of the functional appearance of the upper level and minimize the functional inadequacy or redundancy of the complex.
