Air transportation — Flight simulator — Heart rate — Variability — Pilots psychophysiological state — Wavelet transform


Due to increasing safety standards in air transport, the emphasis is put on human factors in this domain. This
regards especially the improvement of piloting precision during flight training and the elimination of internal and
external influences with negative effect on pilots. This paper is focused on evaluation of pilot’s psychophysiological
state during flight training on a simulator and in an aircraft and also on pilot’s reaction on transfer from analogue
to digital visual presentation of avionic data. The best indicator for evaluating human’s psychophysiological
condition could be a heart rate because of its descriptive activity of human heart and its psychophysiological
character based on sympathovagal balance of autonomic nervous system. In this paper heart rate frequency
is measured by FlexiGuard biotelemetry mobile device and by a Garmin c
 chest belt. This paper is oriented
towards description and comparison of the most common methods for physiological parameters assessment, i.e.
time and frequency domain analysis and non-parametric methods analysis. The paper also describes a wavelet
transform. The results show that not every parameter resulting from each analysis could be a good indicator
describing pilot’s stress. Results also show which parameters might work as good indicators of pilot’s stress
– those are LF/HF ratio and parameters measured by wavelet transform. Best way to define pilot’s stress on
simulators in real time indicates to be wavelet.
