What is the maximum operating altitude for passenger oxygen system deployment?

The maximum operating altitude for passenger oxygen system deployment is established based on safety protocols designed to ensure adequate oxygen supply when cabin pressure drops. This threshold is set at 14,000 feet, where the risk of hypoxia increases for unacclimatized individuals. Above this altitude, the passenger oxygen system is automatically triggered to provide supplemental oxygen, ensuring that all occupants can breathe safely in case of decompression or other emergencies.

By establishing this altitude limit, the aircraft maintains compliance with aviation safety regulations aimed at protecting passenger health. The figures provided reflect standardized practices across commercial aviation to ensure that effective measures are in place well before individuals experience the adverse effects of insufficient oxygen.
