The supplemental oxygen system on the CRJ 700 lasts for how many minutes?

• A. 10
• B. 13
• C. 15
• D. 20

Answer: (B)

The supplemental oxygen system on the CRJ 700 is designed to provide emergency oxygen to the flight crew in the event of cabin depressurization or other situations where supplemental oxygen may be necessary. The correct answer, which states that the system lasts for 13 minutes, is based on the operational specifications and safety requirements for this aircraft model. This duration is crucial for ensuring that the flight crew can effectively manage an emergency situation, allowing enough time to secure the aircraft's safety and to descend to a safe altitude where breathable air is available. The design and regulation of these oxygen systems ensure they meet industry standards for emergency preparedness, which typically aims for a duration that allows for safe and effective response during critical moments. Other options suggest longer durations that would exceed the operational design and intended emergency use of the oxygen system on the CRJ 700.
