Hypoxia Resistance Comparing between Physically Trained Pilots and Non-trained Population

Aviation safety is essential for the ever-increasing density of air traffic as well as piloted aircraft performance at high altitudes. To support these dynamic scenarios to conduct safe flight, the required human performance of pilots begins with sufficient situational awareness. One of the safety pillars in situational awareness is to prevent the pilot from losing vigilance due to the unrecognized effects of hypoxia, which has caused many serious incidents and accidents in the past. The results of civil and military aviation accidents caused by hypoxia have helped to understand the impact of different levels of pilot hypoxia on flight safety; but testing before flight can increase safety and reduce accidents. An important assumption was confirmed that physically trained pilots are better prepared to manage the effects of hypoxia than a sample of the general population. Several steps are subsequently proposed to reduce the number of accidents related to hypoxia in the future.
