Why do airplanes pressurize their cabins?
Even ascending a mile-high mountain can stress people if the climb is steep and they are not in shape, so a rapid change to nearly 3 times that altitude in an unpressurized plane should have some effects on some folks, especially if your pumped about the prospect of jumping out of the thing and your metabolic rate is a bit high.russ_watters said:I'm in pretty good shape, but when I went skydiving, my instructor said I was turning white and gave me oxygen. I think a rapid ascent from sea level to 13,500 feet can be a strain.
Airplanes pressurize their cabins to maintain a comfortable and safe environment for passengers and crew at high altitudes.
Cabin pressure is regulated to mimic the pressure at lower altitudes, which helps prevent the negative effects of high altitude on the body, such as hypoxia (lack of oxygen) and decompression sickness.
If an airplane's cabin is not pressurized, the air inside will become thinner and less oxygen-rich, which can lead to discomfort, dizziness, and even loss of consciousness in extreme cases.
Airplanes have pressurization systems that regulate the air pressure inside the cabin. The system continuously monitors and adjusts the air pressure to ensure it stays at a safe and comfortable level for passengers and crew.
Most commercial airplanes start pressurizing their cabins when they reach an altitude of 8,000 feet or higher. This is because at this altitude, the air becomes too thin for humans to breathe comfortably without supplemental oxygen.
