Abstract:Flight safety is an integral part of air transportation. Flight accidents are highly unlikely to appear but most of them are caused by the human factor. The aircrew training system for abnormal operations relies on integrated aircraft simulator-based exercises. Crew needs to be trained not to degrade piloting technique quality when facing increased psychophysiological tension. Therefore, methods evaluating the characteristics of ergatic aircraft control systems, warning systems for deterioration due to failure… Show more
“…We found the psychophysiological pressure of the human operator during flights from the end of the third turn to the fourth turn, by comparing the data obtained on the flight simulator (FS) in the case of complex failures that do not affect aerodynamics and aircraft control systems. Predicted limits of entry into the glide path by correlation functions in the form of an ellipsoid are presented in [6].…”

The article presents aircraft flight data in the landing approach mode, which was obtained on an integrated flight simulator and in actual flight conditions, processed by various probabilistic-statistical methods. These data were used to assess the quality of flight crew piloting techniques. We have reviewed the methods based on the Neyman–Pearson criterion, and the optimal Bayesian criterion is considered. When using them, we revealed the presence of a deterministic sinusoidal component in the flight parameters. We also used the method of analyzing autocorrelation functions and the method of analyzing the spectra of flight parameters of normalized and unnormalized autocorrelation functions. In a comparative analysis of these methods, we have shown that the most informative approach is the analysis of the spectra of flight parameters of normalized and unnormalized autocorrelation functions. This paper shows that the successful completion of the landing stage largely depends on the accuracy of the aircraft entry to the glidepath intercept point.

This article deals with issues related to assessing the impact of the pilot's psychophysiological pressure on the quality of the flight piloting technique. The quality of the aircraft control technique was evaluated by changing one of the flight parameters, namely the pitch angle during the landing approach. The analysis of the autocorrelation functions of the controlled parameter and their spectra were used to conduct the research. The proposed mathematical apparatus makes it possible to track the moment the pilot's psychophysiological pressure increases to a state of emotional instability, build a function of its influence on the quality of the flight piloting technique, and develop an effective method of anti-stress training for crews.
