Will the supplemental oxygen system automatically deploy once the cabin altitude reaches 14,000 feet?

The supplemental oxygen system is designed to automatically deploy when the cabin altitude exceeds 14,000 feet. This deployment ensures that passengers and crew have access to supplemental oxygen to maintain adequate oxygen levels in case of a loss of cabin pressure. When the environment inside the aircraft becomes unsafe for breathing, the system activates to prevent hypoxia, which can occur at higher altitudes.

Understanding this mechanism is crucial for both safety procedures and emergency protocols in aviation. The system's automation reduces the need for immediate manual intervention by the crew, ensuring that oxygen is available for all occupants during critical altitude thresholds.
