What function does the cabin pressure controller serve in a typical Cabin Atmosphere Control System?

• A. It automates the control of lighting systems
• B. It monitors cabin noise levels
• C. It automates the control of outflow valves based on altitude changes
• D. It manages passenger announcements

Answer: (C)

The cabin pressure controller's primary function is to automate the control of outflow valves in response to changes in altitude. This is crucial for maintaining a safe and comfortable cabin pressure within an aircraft. As the aircraft ascends or descends, the ambient air pressure outside changes significantly, and the cabin pressure must be adjusted accordingly to ensure passenger safety and comfort. To achieve this, the cabin pressure controller continuously monitors the altitude and makes real-time decisions to open or close the outflow valves. This ensures that the pressure inside the cabin is regulated, preventing it from becoming too high or too low during flight. This automation simplifies the process for pilots, allowing them to focus on other aspects of flight management and enhancing overall safety by maintaining precise control over cabin pressure.
