It does not amend broader Regulations or Civil Aviation Orders; it establishes conditions that the operator must meet for that specific approval."},"complexity_factors":["Narrow, aircraft‑specific scope (applies only to VH‑HQB) which reduces breadth of application","Technical performance condition defined as an altitude‑dependent flow‑rate profile (0.3 L/min at 10,000 ft; +0.1 L/min per 2,000 ft up to 18,000 ft)","Cross‑reference to Civil Aviation Orders (section 108.26, paragraphs 6.1 and 5.1.2) creates dependency on external technical requirements","Delegated administrative approval under subregulation 207(2) — introduces discretion and case‑by‑case implementation","Operational compliance tasks (testing, verification, maintenance and provisioning of alternate approved units) create practical complexity for the operator"],"plain_english_summary":"This delegated CASA approval authorises a single aircraft (VH‑HQB) to carry and use the Oxymizer nasal‑cannula oxygen device, subject to a specified minimum oxygen flow profile by altitude and a requirement that any other nose‑and‑mouth units meet referenced Civil Aviation Orders.

It allows flexibility (using potentially more comfortable nasal cannulas) while maintaining safety (requiring backup full masks and minimum oxygen flow rates)."}},"importantCases":[],"_links":{"self":"/api/acts/casa-319-03-approval-under-subregulation-207-2","history":"/api/acts/casa-319-03-approval-under-subregulation-207-2/history","analysis":"/api/acts/casa-319-03-approval-under-subregulation-207-2/analysis","conflicts":"/api/acts/casa-319-03-approval-under-subregulation-207-2/conflicts","importantCases":"/api/acts/casa-319-03-approval-under-subregulation-207-2/important-cases","documents":"/api/acts/casa-319-03-approval-under-subregulation-207-2/documents"}}
