Spectral Analysis of Autocorrelation Functions of Roll and Pitch Angles

This article addresses issues related to assessing the impact of a pilot's psychophysiological stress on the quality of aircraft piloting techniques. The quality of aircraft control was evaluated through changes in flight parameters, specifically the roll and pitch angles during the landing approach. The study utilized the analysis of autocorrelation functions of the controlled parameter and their spectra. The proposed mathematical apparatus allows tracking the moment when the pilot's psychophysiological stress increases to the point of emotional instability, constructing a function of its influence on the quality of aircraft piloting. This method is necessary for improving crew training for special situations in flight.
