What range is considered charged for the emergency oxygen cylinder?

The range considered charged for the emergency oxygen cylinder is 1,800 to 2,500 PSI. This range is significant because it indicates that the cylinder contains a sufficient amount of oxygen for emergency use, which is critical for health and safety during flights or in other emergency situations. Properly maintaining the pressure within this range ensures that the oxygen supply is ready and effective when needed. Maintaining pressure within this specified range helps to guarantee that the oxygen is available for delivery at the required flow rates to support passenger or crew safety under demands of altitude or in emergencies. Understanding the importance of this pressure range is vital for those managing aircraft safety equipment.
