As part of our Airspace and Future Operations consultation we consulted on a proposed short-term change to the way some aircraft arrive at Heathrow. This is known as Independent Parallel Approaches (or 'IPA') and involves some new arrival routes into Heathrow from the holding stacks. Some of these flight paths could overfly areas that are not affected by Heathrow arrivals today.
The introduction of IPA requires an airspace change to be approved by the CAA and our consultation on IPA will form part of our engagement with local communities and affected stakeholders.
IPA will make us more efficient and more resilient to disruption, reducing the chances of delays for passengers. Any airspace changes required would be replaced by our longer term airspace design, if our third runway is approved.
Between September and November 2018, we engaged with our local stakeholder and community groups as well as industry experts to gather feedback on the key design principles we could use to design our flight paths for IPA. We also commissioned a series of focus groups with members of the public who live in areas less affected by today's operations, but which may potentially be affected by the new IPA flight paths in the future.
We submitted these design principles to the CAA on 3 December 2018 which were approved by the CAA at the end of December 2018.
Our submission and all supporting appendices are available on the CAA website and can also be found below:
