Which oxygen system deploys masks in response to cabin decompression, including the cabin, lavatories, and galley?

• A. Emergency cabin oxygen system
• B. First aid oxygen system
• C. Supplemental oxygen system
• D. Portable oxygen system

Answer: (A)

The main idea is that automatic, fixed oxygen deployment across the cabin is provided by the emergency cabin oxygen system. In a decompression event, this system drops oxygen masks from overhead panels for all occupied areas, including the cabin, lavatories, and galley, to give passengers and crew immediate oxygen without needing to request it. This automatic, whole-cabin coverage distinguishes it from other types of oxygen systems. The first aid oxygen system is for medical oxygen needs and isn’t tied to cabin decompression or automatic mask deployment. The supplemental oxygen system is typically used for crew or specific operations and doesn’t automatically furnish masks to the entire cabin. Portable oxygen systems involve individual, hand-carried units and aren’t deployed across the cabin automatically. So, the emergency cabin oxygen system is the one designed to deploy masks throughout the cabin, lavatories, and galley in response to decompression.
