Introduction. Today the problem of maintaining a high level of health and working capacity of military pilots has become a priority in the structure of provision of fly safety and high level of operational readiness. The constant tension of compensative and defensive mechanisms of pilots requires a special approach to health provision. That is why studies on the effect of occupational load on psychophysiological state of pilots are actual and require careful investigations

The purpose of the research. To assess the effect of occupational load of different levels on psychophysiological state of the flight personnel.

Materials and methods. Assessment of psychophysiological state of pilots was made by indices of psychophysiological functions, health status, age, length of service and occupational load. The examination covered 72 pilots, which were divided into 3 groups, depending on the number of flights: with high general number of flights (9 persons), average number (55 people) and low (8 people). Hygienic, psychophysiological and mathematical methods were used in the study.

Results. The complicated changes in the pilot's body have been revealed, depending on the level of an occupational workload. However, these changes do not lead to significant changes in the psychophysiological state of the body and, in conditions of maintaining the standard level of health, it allow to sufficiently meet their professional duties. The peculiarities of transformation in the structure of correlations between indices of psychophysiological functions, age, length of service and health status of pilots with different levels of occupational loads have been found. In particular, it was found that the occupational load caused a self-developing effect on formation of relationships between psychophysiological functions only for pilots with low occupational load level. With load increasing to the average and high ones the characteristics of age and length of service turns to be the determining ones.

Key words: occupational load, psychophysiological function, pilots
