What is the maximum cabin altitude during cruise operations?

The maximum cabin altitude during cruise operations for the CRJ 200 is established to ensure passenger and crew safety and comfort. The correct answer reflects the operational limits set by aircraft manufacturers and regulatory agencies. For the CRJ 200, during normal cruise operations, the maximum cabin altitude is indeed 8,700 feet.

Maintaining this altitude in cruise is critical because it helps to avoid hypoxia, a condition caused by insufficient oxygen at high altitudes. By keeping the cabin altitude at or below 8,700 feet, the aircraft ensures that all occupants can breathe comfortably without supplemental oxygen, which is particularly important for maintaining cognitive function and physical well-being during flight.

The other altitude options provided exceed the operational limits for cabin altitude, which could lead to discomfort for those onboard and potential safety risks. Thus, understanding these limits is essential for pilots and cabin crew to ensure compliance and the safety of all passengers during flight.
