How Cabins Are Pressurized Airplane cabins are pressurized by forcing air into the cabin. Why Pressurized Cabins Are Necessary Cabins are pressurized to create a safe and comfortable environment for pilots, crew and passengers.

The good news is that modern-day airplanes are designed with redundancy measures in case of pressurization failure. Passengers can place one of these oxygen masks over their face to obtain a sufficient amount of oxygen until the airplane descends and lands.

These overflow valves are automatically controlled by the onboard computers, but pilots are also able to control these outflow valves.

When the pressure inside the cabin needs to be lowered, the outflow valves open up to allow air. The process is also called bleeding the air inside the cabin. In a controlled manner, the valve is opened and shut to control the air pressure inside the cabin.

The valve continues to function throughout the journey, which means that a fresh cycle of air is bled inside the cabin every 2 to 3 minutes. In some aircraft, the pressure comes from the combustion of the engine. The hot combustion air also protects the airplane engine and wings from ice buildup at high altitude.

When a cabin is suddenly depressurized, oxygen masks pop out of the upper sockets to provide oxygen supply to passengers. Despite the availability of oxygen, a depressurized cabin can prove dangerous because passengers will be in danger of hypothermia and hypoxia.

They will be exposed to severe cold and the effect of altitude changes if the plane climbs down quickly to avert the situation. Under these circumstances, pilots are trained to bring the airplane to altitudes of around 8, to 10, feet gradually.

The low altitude would allow passengers to avoid health injuries related to a depressurized cabin. According to experts, if the cabin depressurization occurs due to a blown-out door or an open space, the cabin will be enveloped by a misty fog.

Small objects and tissue papers will fly around the cabin.
