This instrument creates a temporary exception for qualifying gliders, meaning they don't need to display this mark even though other aircraft still must.\n\n**Why it matters:**\nIt reduces administrative burden for gliding operations while maintaining safety through existing registration requirements with the Gliding Federation of Australia."}},"importantCases":[],"_links":{"self":"/api/acts/casa-ex39-17-exemption-display-of-markings-gliders-and-powered-sailplanes","history":"/api/acts/casa-ex39-17-exemption-display-of-markings-gliders-and-powered-sailplanes/history","analysis":"/api/acts/casa-ex39-17-exemption-display-of-markings-gliders-and-powered-sailplanes/analysis","conflicts":"/api/acts/casa-ex39-17-exemption-display-of-markings-gliders-and-powered-sailplanes/conflicts","importantCases":"/api/acts/casa-ex39-17-exemption-display-of-markings-gliders-and-powered-sailplanes/important-cases","documents":"/api/acts/casa-ex39-17-exemption-display-of-markings-gliders-and-powered-sailplanes/documents"}}
