This approval allows a more comfortable nasal cannula alternative for this specific aircraft, but only under strict conditions to ensure safety. The backup requirement ensures that if the nasal cannula fails or is insufficient, proper full-face masks are available."},"flash_summary":{"complexity_score":3,"scope_assessment":{"changed":false,"description":"The instrument is a limited, conditional approval that permits the named aircraft (VH‑SMK) to operate with Oxymizer nasal cannula oxygen units if they meet the stated technical conditions.
