Abstract

Hypoxia is a physiological state defined as a reduction in the distribution of oxygen to the tissues of the body. It has been considered as a major factor in aviation safety worldwide because of its potential for pilot disorientation. Pilots are able to operate aircrafts up to 3810 m without the use of supplemental oxygen and may exhibit symptoms associated with hypoxia.

PURPOSE: To determine the effects of 3810 m on physiology, cognition, and performance in pilots during a flight simulation.

METHODS: Ten healthy male pilots engaged in a counterbalanced experimental protocol comparing a 0 m normoxic condition (NORM) with a 3810 m hypoxic condition (HYP) on pilot physiology, cognition, and flight performance.

RESULTS: Repeated-measures analysis of variance demonstrated a significant (p ≤ 0.05) time by condition interaction for physiological and cognitive alterations during HYP. A paired samples t test demonstrated no differences in pilot performance (p ≥ 0.05) between conditions.

CONCLUSION: Pilots exhibited physiological and cognitive impairments; however, pilot performance was not affected by HYP.
