In general, a majority of aircraft operate in high altitude conditions, often ranging from 31,000 to 38,000 feet. At such heights, temperatures and the density of oxygen can be dangerously low, presenting a risk to anyone without sufficient protection. Despite this, most passengers and aircraft operators never worry about the comfort of breathing or the extreme cold during typical flights. This is because of cabin pressurization, allowing for passengers, pilots, and crew to safely travel in aircraft at high altitudes. In this blog, we will discuss what cabin pressurization is, how it is achieved, and how it benefits all of those on an aircraft during flight.
