For how long will the oxygen generator produce oxygen for passengers and crew?

The oxygen generator is designed to provide supplemental oxygen for a specific duration in the event of cabin depressurization. In commercial aviation, oxygen systems are engineered to ensure that passengers and crew have sufficient oxygen supply to safely breathe until the aircraft can descend to a lower altitude where breathable atmospheric conditions are restored.

The correct duration for which the oxygen generator produces oxygen is approximately 12 minutes. This time frame allows adequate time for the aircraft to execute an emergency descent to a safe altitude and for passengers to don their oxygen masks, thereby ensuring their safety and well-being during critical situations.

While other choices reflect common assumptions about oxygen supply durations in different contexts, 12 minutes is specifically aligned with aviation safety protocols and the engineering standards used by aircraft manufacturers.
