For a typical commercial flight, such aircraft operate at an altitude between 31,000 and 38,000 feet. At such altitudes, humans would quickly face various physiological problems due to the lack of air pressure present, possibly resulting in hypoxia, altitude sickness, loss of consciousness, and more if left unprotected. This is why many aircraft are pressurized and supplied with fresh oxygen throughout the flight, providing passengers and crew members with a safe and comfortable environment while operating at heights that bring more flight efficiency. In this blog, we will discuss the aircraft pressurization system, allowing you to familiarize yourself with how cabin pressurization is upheld.
