What is the normal pressure range for the passenger oxygen system?

The normal pressure range for the passenger oxygen system being 285 - 430 psi is critical for ensuring that the system functions effectively and provides adequate oxygen to passengers in case of an emergency. This range ensures that the oxygen can be delivered at sufficient pressure to be utilized by passengers during situations where cabin pressure may be compromised, such as during rapid decompression.

Maintaining oxygen systems within this specific pressure range is vital for safety, as it helps to ensure that the oxygen is readily available for use and that the system operates without failure. If the pressure were to fall below or exceed this range, it could pose a risk of insufficient oxygen delivery or excessive pressure, which could damage the system.

Understanding this range is essential for pilots and crew members responsible for monitoring the aircraft’s safety systems and responding appropriately in emergency situations. This knowledge directly contributes to the overall preparedness and safety protocols during flight operations.
