What is the duration of the CRJ 200 passenger oxygen system?

The duration of the CRJ 200 passenger oxygen system is 13 minutes. This is a critical aspect of the aircraft's safety features, as passenger oxygen systems are designed to provide supplemental oxygen in the event of cabin depressurization.

A 13-minute duration is generally sufficient to allow passengers to maintain consciousness until the aircraft descends to a safer altitude where breathable air is available. This time is carefully calculated to ensure that it meets the safety requirements mandated by aviation regulatory authorities.

Other durations, such as 10, 12, or 15 minutes, do not align with the operational specifications of the CRJ 200, which is why they are not correct in this context. Understanding the precise operation of safety systems like the passenger oxygen system is vital for ensuring passenger safety and compliance with regulations during flight operations.
