[Ecological aspects of aviation ergonomics].

The authors analyzed human role in ecologic system, using the principle "human--environment--health", and human function in ecologic and ergonomic system, using the principle "operator--environment--occupational reliability" for aviation ergonomics. Unfavorable ecologic environment influencing the operator was considered a complex stress factor composed of objective environmental and emotional elements. The authors describe human response to physiologically adequate and inadequate stress factors. The article stresses good prospects associated with application of aviation ergonomics to targeting some problems.
