pressurization


pressurization
i. A form of climate control of an aircraft. It is a means of increasing the partial pressure of oxygen in the cabin of an aircraft flying at a high altitude by increasing the air pressure in the cabin to that of an altitude that requires no supplemental oxygen. Without pressurization, supplemental oxygen is required above altitudes approximately 10,000 ft (3 km).
ii. A method of increasing pressure so that fluids can be delivered under positive pressure (e.g., a fuel tank pressurization system).
