What is the duration of the passenger oxygen system on most CRJ 700 aircraft?

The duration of the passenger oxygen system on most CRJ 700 aircraft is typically 13 minutes. This timeframe is designed to provide sufficient oxygen supply for passengers in the event of a decompression or similar emergency, allowing enough time for the aircraft to descend to a safer altitude where breathable air is available.

The 13-minute duration is based on the operational requirements and safety standards governing commercial aviation, taking into account factors such as cabin altitude, the number of passengers, and standard emergency procedures.

While other durations may be considered for different aircraft types or configurations, the specific design of the CRJ 700’s oxygen system is calibrated to ensure effective and timely support for passengers during emergency situations.
