Which device is described as Supplemental Oxygen Equipment and can be configured as single or dual canisters?

• A. Flight Deck Oxygen System
• B. PSU
• C. Aviox Oxygen Units
• D. ELS

Answer: (C)

Supplemental Oxygen Equipment covers portable oxygen sources used to provide extra oxygen to passengers or crew in the cabin when needed. Aviox Oxygen Units are a type of this portable equipment and are designed to be configurable with either a single canister or dual canisters, depending on the required oxygen supply and duration. This flexibility lets crew tailor the system to the situation—one canister for lighter, shorter needs, or two canisters to increase capacity. The other options don’t fit this description: the Flight Deck Oxygen System serves the pilots and isn’t a portable, configurable unit; the PSU is the cabin panel with oxygen masks built in rather than a standalone portable supply; and ELS is an emergency locator system, not oxygen equipment.
