This approval allows an exception for one specific aircraft to use more comfortable nasal cannulas instead, but only if strict safety conditions are met and proper backup equipment is still available. This kind of individual approval is common in aviation where specific equipment needs to be assessed case-by-case for safety."},"flash_summary":{"complexity_score":3,"scope_assessment":{"changed":false,"description":"The instrument itself is a targeted approval for a single aircraft registration (VH-LCA) and specifies conditions for using Oxymizer nasal-cannula oxygen units and for other carried devices.
