PILOTS PERFORMANCE AND FLIGHT SAFETY: FLIGHT PHYSIOLOGY IN UNPRESSURIZED AIRCRAFT CABINS

摘要

Light aviation pilots are exposed to many different environmental situations due to theunpressurized and unacclimatized aircraft cabin. A literature review on this theme suggeststhat a significant part of the incidents and fatalities;;within the aviation that usesunpressurized aircraft cabins;;are related to the human factor. This may be a concerningsituation due to the disparity of human body reaction between different pilots to the sameflight conditions.jmiguel@ubi.ptABSTRACTThis study general objective is to analyse the influence of flight environmentalconditions and pilots psychophysiological parameters on task performance;;during differentflight situations;;considering some of his everyday habits. To this end a portable andergonomic monitoring system was built. This system records the cerebral oximetry;;tostudy the hypoxia phenomenon;;and the atmospheric pressure;;in order to correlate theinfluence of altitude with the pilot’s physiological response;;during different flight stages.With the experimental work was observed that the physiological reaction to thepsychological factors;;as arousal;;stress and fatigue;;combined with the environmentalconditions can highly influence the pilot’s physiological response.With this research is also intended to suggest that a potential restriction on pilotslicensing legislation for light aviation;;regarding specific physiological parameters;;wouldbe a positive contribution to a safer flight environment.
