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

In aviation, high-pressure oxygen systems are commonly utilized due to their ability to store large amounts of oxygen in a relatively small space, which is essential for flight at high altitudes where cabin pressure can be significantly lower and the availability of breathable air is reduced. High-pressure oxygen systems often operate at pressures around 1800 to 2200 psi, enabling aircraft to ensure sufficient oxygen supply for crew and passengers, particularly during emergency situations or in pressurized environments where supplemental oxygen may be required.

This high-pressure capability allows for efficient storage and quick delivery of oxygen during critical phases of flight, such as emergencies or when flying above certain altitudes where supplemental oxygen is mandated by regulations. Understanding this aspect of oxygen systems is crucial for ensuring the safety and well-being of everyone aboard an aircraft.
