Study: High CO2 Levels Diminish Pilot Performance
The study concluded that there is a “direct effect of carbon dioxide on performance, independent of ventilation.”

High concentrations of carbon dioxide (CO2) were linked to a decrease in pilot performance in a simulator study that assessed the flying of maneuvers in flight deck atmospheres containing varying concentrations of CO2. The study, by the Harvard T.H. Chan School of Public Health, was published last week in the Journal of Exposure Science and Environmental Epidemiology.
