It affects nearby property owners, developers and planning authorities by giving the Department of Defence grounds to object to developments that breach those limits, reducing risks to aircraft during take-off, landing and training."}},"importantCases":[],"_links":{"self":"/api/acts/defence-raaf-base-edinburgh-defence-aviation-area-declaration-2018","history":"/api/acts/defence-raaf-base-edinburgh-defence-aviation-area-declaration-2018/history","analysis":"/api/acts/defence-raaf-base-edinburgh-defence-aviation-area-declaration-2018/analysis","conflicts":"/api/acts/defence-raaf-base-edinburgh-defence-aviation-area-declaration-2018/conflicts","importantCases":"/api/acts/defence-raaf-base-edinburgh-defence-aviation-area-declaration-2018/important-cases","documents":"/api/acts/defence-raaf-base-edinburgh-defence-aviation-area-declaration-2018/documents"}}
