Hryshchenko Y. Methods for assessing the characteristics of aircraft ergatic control systems

The thesis is devoted to the development of methods for evaluating the characteristics of aircraft ergatic control systems. The issues of identifying the degree of psychophysiological tension of a human operator during the glide path entering, landing and go-around are considered. The principle of invariance of pilots' control actions and changes in flight parameters has been substantiated. In order to assess the characteristics of the phenomenon of the flight parameters amplitude increase (IFPA), methods of analysis of correlation, autocorrelation functions and their spectra, distribution laws and trend algorithms of flight parameters are used. Algorithms for extracting the deterministic component from the random process of changing the flight parameters have been developed. The flight trajectories are considered in ideal and extreme conditions by means of correlation and autocorrelation functions. As a result of the analysis, it was shown that the delay in entering the glide path by aircraft is more dangerous for the quality of the approach than the advance of entering. A geometric interpretation of the probability of deviation from a given point while entering the glide path in three-dimensional space is presented. This makes it possible to determine the probabilities of inaccurate the glide path entry from the autocorrelation functions. It has been established that the determination of complex aircraft avionics failures by the method of contour correlation fields makes it possible to create a new type of failure analyzers that help the pilot to recognize a difficult flight situation and make the right decision. The above theoretical conclusions are confirmed by the method of analysis of the autocorrelation functions of the roll angle and their spectra. Methodological guidelines and recommendations for evaluating the characteristics of ergatic aircraft control systems are presented. A program has been developed to assess the tension of aviation specialists who are not directly related to piloting. The systems for controlling the quality of the piloting technique that prevent sudden movements of pilots during go-around, by signaling of inaccurate information on the angles of attack, roll and indicated airspeed and give the algorithm of actions have practical value.
