This approval lets VH-JEL use nasal cannulas (tubes that sit in the nose only) instead, but only if two conditions are met:\n\n* **Flow rate requirement:** The oxygen flow must be at least 0.3 litres per minute at 10,000 feet altitude, and must increase by 0.1 litres per minute for every 2,000 feet of additional altitude up to 18,000 feet.\n* **Backup requirement:** The aircraft must still carry standard oxygen masks that cover nose and mouth as backup, and these must meet specific technical standards set out in the Civil Aviation Orders.\n\n**Who it affects:**\nOnly the operators and passengers of the specific aircraft VH-JEL. This is a one-off approval, not a general rule change.\n\n**Why it matters:**\nIt shows how aviation safety works in practice — CASA can grant specific exemptions from standard rules when alternative equipment meets equivalent safety standards. The nasal cannulas are lighter and more comfortable, but the approval ensures safety isn't compromised by requiring minimum oxygen flow rates and maintaining backup equipment."}},"importantCases":[],"_links":{"self":"/api/acts/casa-295-99-approval-under-subregulation-207-2","history":"/api/acts/casa-295-99-approval-under-subregulation-207-2/history","analysis":"/api/acts/casa-295-99-approval-under-subregulation-207-2/analysis","conflicts":"/api/acts/casa-295-99-approval-under-subregulation-207-2/conflicts","importantCases":"/api/acts/casa-295-99-approval-under-subregulation-207-2/important-cases","documents":"/api/acts/casa-295-99-approval-under-subregulation-207-2/documents"}}
