Development of a new concept for assessing work intensity of civil aviation pilots

The article describes a concept for assessing work intensity (LI) developed by the authors. This concept is based on the results produced by comprehensive assessment of the current working conditions, by analyzing the psychophysiological state of civil aviation (CI) pilots in flight, as well as by assessing a contribution made by flight loads and signs of fatigue to an increase in a risk of aviation accidents (AA). It has been established that, according to sanitary and hygienic profiles, LI levels at all workplaces of civil aviation pilots correspond to harmful working conditions, which are aggravated by exposure to four other harmful factors (noise, microclimate, vibration, and working posture) in 48 % of cases. The research results have shown that the risks of fatigue increase significantly after 5 hours of flight. This fatigue manifests itself in the growing number of gaze fixations by 11 %; an increase in an average latency period of a complex visual-motor reaction, by 12 %; the growing number of significant errors for flight safety, by 50 %. All these processes occur in the absence of physiological recovery of the cardiovascular system, p function show_eabstract() { $('#eabstract1').hide(); $('#eabstract2').show(); $('#eabstract_expand').hide(); }
