Abstract: The subject of the study is ergonomic security of information display and ergatic complex control systems, measures and functions of the "developer-client" parties during various stages of the life cycle of an aviation ergatic complex prototype, in order to ensure a comprehensive registration of the human factor. The research is performed on the subject of aviation ergatic complexes, and this ensures the broadest scope of results, because such systems are among the most tecnhologically complex ergatic systems, and the cost of a human error by the operator is very high. The methodology of this research involves adaptive control, system analysis, psychology of labour, probability theory, engineering psychology, reliability theory and psychophysiology. The main result of this research is the systematization of ergonomic security of information display systems, which are the basis of securing safe and efficient operation. Comprehensive realization of those methods ensures the most complete record of the human factor in order to optimize interaction of the ergatic system operator with its technical components.
