Psychophysiological Factors Analysis in Unpressurized Aircraft Cabins
(Comunicação em Conferência)
In the versatile aviation environment, the pilot’s well-being is a crucial and demanding factor which is directly related to his good performance. Due to the unpressurized and unacclimatized aircraft cabin, light-sport aircraft pilots are exposed to many diﬀerent environmental conditions. Actually, a brief research on this matter suggests that a signiﬁcant part of the incidents and accidents are related to the human factors. In order to evaluate factors as oxygen saturation, heart rate and stress level, and how they may inﬂuence or even compromise the pilot’s performance, experimental tests were realized in diﬀerent scenarios with diﬀerent pilots. In this study was possible to observe each individual variation of oxygen and heart rate for diﬀerent stressful situations, at diﬀerent altitudes and environments as hypobaric chamber, ﬂight simulator and real ﬂight scenarios. During the tests was possible to observe that, for the same altitude but in diﬀerent situations, the same pilot had diﬀerent hypoxia and heart rate levels; this may suggest that the stress level can compromise the pilot’s psychophysiological response and, consequently, his performance.
