AviOX Oxygen Units are described as which type of equipment?

• A. Primary oxygen supply
• B. Supplemental Oxygen Equipment
• C. Emergency Oxygen System
• D. Portable Oxygen Bottle

Answer: (B)

The main idea here is how oxygen systems are categorized on an aircraft. Oxygen devices fall into distinct groups based on their role in flight operations: a fixed primary supply that supports crew in a decompression, an emergency system that automatically deploys for all occupants, and supplemental oxygen equipment that provides additional, on-demand oxygen for medical or individual needs without being part of the fixed systems.

AviOX Oxygen Units are described as supplemental oxygen equipment because they’re used to supply extra oxygen to a passenger or crew member as needed, outside the aircraft’s primary fixed system. They’re portable and meant for targeted use during medical events or relief of hypoxia, rather than being the aircraft’s main oxygen source or part of the automatic emergency deployment. They’re not simply a single portable bottle, but a set designed to augment oxygen delivery as part of the supplemental equipment ensemble.
