The possibilities for using evoked potentials to diagnose fatigue among flight crews when they are performing their jobs are studied. The basic theoretical premise was the accepted fact that as fatigue develops, the physiological price of activity increases, reserve possibilities for processing additional information decline, and performance of a flying assignment worsens in the dynamics of pilot performance. A 10-hour flight on a route with alternating cycles of manual and automatic control was modeled on a flight simulator. An electroencephalogram was recorded during the landing approaches. Auditory stimuli irrelevant to the operator were used to obtain auditory evoked potentials (AEPs). Traditional indicators were used in the analysis of average AEPs - the latent periods of isolated components and their amplitudes. Before and after the experiment the operator used a special scale to evaluate the level of their feeling of fatigue. The quality of activity associated with the landing approach was evaluated.
