Which type of oxygen system pressure is typically used in aviation?

In aviation, high-pressure oxygen systems are commonly utilized primarily due to their ability to store a significant amount of oxygen in a relatively small and compact space. This capability is crucial in an aircraft, especially at higher altitudes, where the oxygen levels in the atmosphere decrease significantly. High-pressure systems can deliver oxygen efficiently for both cabin pressurization and supplemental oxygen needs for pilots and passengers during emergencies.

These high-pressure systems usually operate at pressures ranging from about 1,500 psi to 2,000 psi, allowing them to maintain an adequate supply while being lightweight and space-efficient. This is essential for ensuring safety and performance during flight, particularly in scenarios involving decompression or loss of cabin pressure. The implementation of such systems enhances the overall safety protocols in aviation, allowing for quick and effective response to altitude-related physiological conditions.
