[Bases of differentiated evaluation of mental health of flying personnel].

Relying on the authors' experimental and literary data concerning flying personnel, the classification criteria were substantiated and the following levels of mental health defined: "healthy" (level 1), "apparently healthy" (level 2), "presence of unfavorable prognostic signs" (level 3); in the interests of organization/certification decision, level 4, "symptoms of psychic pathology", was also identified. These levels of mental health have been defined from a set of indices and a measure of their manifestation, e.g., inherent/anamnestic, personal and medical risk factors for developing psychic decompensation, failures in the systems of attitudes, severity of clinico-psychological deviations, characteristics of occupational reliability, and successful flight activity. The examination of flying personnel with varying levels of mental health in hospitals and aviation units demonstrated their significant distinction in clinical/anamnestic signs, psychophysiological characteristics, mean number of erroneous actions per 100 flight hours, and the judgement of command about occupational efficiency.
