[Study of the dynamics of psychic work capacity of hypertensive flight personnel for the purpose of predicting their professional activity].

One hundred members of the flying personnel with hypertensive disease (of the I and II stages), aged 35--50, were examined. The examinations included clinical and psychological observations which described functional and psychological potentialitites of the test subjects. Statistically significant differences in the average productivity of mental work were found in hypertensive and control test subjects. Individual characteristics of the prolonged and intensive mental activity was determined. This makes it possible to reveal consistent tendencies characterizing different disturbances in mental performance. Clinical and psychological investigations allow objectivization of qualitative features of disorders in mental capacity typical of the I and II stages of hypertension. They are helpful in predicting professional reliability of the flying personnel. Therefore, they should be taken into consideration in solving expertise problems.
