This approval creates an exception for one specific aircraft to use lighter, more comfortable nasal cannulas instead—but only if they meet precise flow-rate requirements and the aircraft still carries standard masks as well. This kind of specific exemption (called a \"delegate's approval\") allows flexibility while maintaining safety standards."}},"importantCases":[],"_links":{"self":"/api/acts/casa-1097-99-approval-under-subregulation-207-2","history":"/api/acts/casa-1097-99-approval-under-subregulation-207-2/history","analysis":"/api/acts/casa-1097-99-approval-under-subregulation-207-2/analysis","conflicts":"/api/acts/casa-1097-99-approval-under-subregulation-207-2/conflicts","importantCases":"/api/acts/casa-1097-99-approval-under-subregulation-207-2/important-cases","documents":"/api/acts/casa-1097-99-approval-under-subregulation-207-2/documents"}}
