This approval allows an alternative (nasal cannulas) for this specific aircraft, which may be more comfortable for passengers but still safe if the conditions are met. It's an example of how aviation safety regulators can grant specific exemptions or alternative approvals for individual cases."}},"importantCases":[],"_links":{"self":"/api/acts/casa-1082-99-approval-under-subregulation-207-2","history":"/api/acts/casa-1082-99-approval-under-subregulation-207-2/history","analysis":"/api/acts/casa-1082-99-approval-under-subregulation-207-2/analysis","conflicts":"/api/acts/casa-1082-99-approval-under-subregulation-207-2/conflicts","importantCases":"/api/acts/casa-1082-99-approval-under-subregulation-207-2/important-cases","documents":"/api/acts/casa-1082-99-approval-under-subregulation-207-2/documents"}}
