The Government continues to expect airports to help local communities understand the noise impacts they are affected by, through appropriate noise monitoring and the provision of relevant information.
At this stage, it is not possible to identify the exact noise impacts on specific communities after potential expansion.
The Appraisal of Sustainability that accompanies the revised draft Airports National Policy Statement provides a strategic level assessment of the unmitigated noise impacts of expansion based on indicative flightpaths.
If the revised draft Airports NPS is designated, precise flight paths for the Northwest Runway scheme would be defined through the Civil Aviation Authority’s Airspace Change Process. It is through this regulatory process that communities would see and have the opportunity to comment on the detailed proposals for new flightpaths. Any such proposals would need to take account of the Department’s new policies on appraising options for airspace design.
In addition, the Government expects an applicant for development consent for Heathrow expansion to commit to a package of supporting measures to limit the impacts of noise on local communities, including the provision of more predictable periods of respite. These supporting measures would be finalised through the planning process, or the exercise of statutory powers, and be subject to public consultation.
