Final answer:
When the cabin pressurization mode is set to AUTO, the system automatically adjusts the cabin pressure. In manual mode, the pilot has control over adjusting the cabin pressure based on specific requirements.
Step-by-step explanation:
When the cabin pressurization mode is set to AUTO, the system automatically adjusts the cabin pressure to maintain a comfortable and safe environment for the passengers and crew. However, when the mode is set to a different position, manual control is enabled, allowing the pilot to manually adjust the cabin pressure.
In manual mode, the pilot can set the cabin pressure according to specific requirements based on factors such as altitude and air pressure outside the aircraft. This allows for more flexibility and control in maintaining the desired cabin pressure.
For example, when flying at higher altitudes where the outside air pressure is lower, the pilot may choose to adjust the cabin pressure to prevent discomfort or health issues for the passengers.
