The NORMAl Pack position uses which pack?

• A. Backup Pack
• B. Auxiliary Pack
• C. Main Pack with AMSAC control
• D. Emergency Pack

Answer: (C)

The NORMAl Pack position utilizes the Main Pack with AMSAC control. This is important because the Main Pack is the primary system that regulates cabin temperature and pressurization during normal operations. The Air Management System Automatic Control (AMSAC) manages the airflow and distribution of conditioned air throughout the cabin, ensuring occupant comfort under typical operation conditions. In contrast, while the Backup Pack, Auxiliary Pack, and Emergency Pack are designed to provide support or alternate means of environmental control, they are not intended for use during standard flight operations when the NORMAl Pack setting is engaged. The Main Pack under AMSAC control is designed specifically for optimal performance and efficiency in maintaining the desired cabin environment, making it the correct position for regular use.
