What happens to airflow when smoke is detected in the AFT Cargo Bay?

When smoke is detected in the AFT Cargo Bay, the system is designed to respond swiftly to ensure the safety of the aircraft and its passengers. The primary action taken is to cut off the airflow to and from the cargo bay. This is crucial because it helps to prevent the spread of smoke and any potential fire from moving into other areas of the aircraft, including the cabin and cockpit.

By isolating the cargo bay, the crew can manage the situation more effectively, allowing them to implement appropriate emergency procedures without complicating the issue with additional ventilation. Additionally, this response aligns with safety protocols that prioritize the containment of smoke and hazardous conditions within confined spaces of the aircraft.
