This Direction says: **if your plane has a flashing white strobe light that can be seen from all directions (within 30 degrees up and down from the horizontal), you don't need the usual anti-collision light.**\n\n**Who it affects:**\n- Owners and operators of Australian-registered aeroplanes\n- Pilots and maintenance engineers who need to know what lighting equipment is legally required\n\n**Why it matters:**\nThis provides flexibility in aircraft equipment. Rather than mandating one specific type of anti-collision light, CASA is saying an alternative (flashing white strobe lights) meets the same safety purpose. This can reduce costs and maintenance burdens while maintaining safety standards — the strobe light must still be visible in all directions with specific angular coverage."},"flash_summary":{"complexity_score":2,"scope_assessment":{"changed":true,"description":"The direction modifies how subregulation 196(3) applies to Australian‑registered aeroplanes by creating an exemption: such aeroplanes do not have to display the anti‑collision light required by subregulation 196(3) if they display a flashing white strobe light visible at any time within 30 degrees above and 30 degrees below the aeroplane’s horizontal plane. The decision to apply this exemption is made by a CASA delegate (Assistant Director, Aviation Safety Standards). The instrument therefore narrows the operational requirement in practice for aircraft that meet the stated visibility condition, without amending the text of the Regulations themselves."},"complexity_factors":["Relies on an external regulatory provision: operates under subregulation 196(3) of the Civil Aviation Regulations 1988 (necessitates cross‑reference).","Technical specificity: sets a precise angular visibility requirement (30 degrees above and below the horizontal plane).","Delegated discretion: issued by a CASA delegate (Assistant Director), showing administrative rather than legislative change.","Implementation detail omission: specifies a performance condition (visibility) but does not set measurement/test procedures or verification processes.","Narrow scope: applies only to aeroplanes having Australian nationality, limiting breadth but also concentrating applicability."],"plain_english_summary":"This CASA direction lets Australian‑registered aeroplanes replace the anti‑collision light required by subregulation 196(3) with a flashing white strobe that is visible in all directions within 30° above and below the aeroplane’s horizontal plane.  \n\nIt affects operators/owners and CASA oversight: operators may fit the strobe instead of the prescribed light but bear responsibility and cost to ensure and demonstrate the strobe meets the visibility condition."}},"importantCases":[],"_links":{"self":"/api/acts/casa-880-99-direction-under-subregulation-196-3","history":"/api/acts/casa-880-99-direction-under-subregulation-196-3/history","analysis":"/api/acts/casa-880-99-direction-under-subregulation-196-3/analysis","conflicts":"/api/acts/casa-880-99-direction-under-subregulation-196-3/conflicts","importantCases":"/api/acts/casa-880-99-direction-under-subregulation-196-3/important-cases","documents":"/api/acts/casa-880-99-direction-under-subregulation-196-3/documents"}}
