pressurization
Forcing air in
Pressurization is the process of maintaining air pressure in an enclosed space, especially an aircraft cabin at high altitude where outside air is too thin to breathe.
The term extends to any system that increases or regulates pressure: The pressurization of the fuel tank ensures consistent flow.
Loss of cabin pressurization is an aviation emergency.
