I thank the hon. Lady for her kindness at the start of her comment, and for the point that she makes. That cap is in place. She is right that, through modernisation, there will be an ability to increase capacity. It might be best if I wrote to her to clarify, because I recognise that her constituents want certainty on this point.

Although a redesign of our airspace might not be as tangible as other major transport projects, it would nevertheless be a vital pillar of future growth of the aviation industry. CAP1616, the Civil Aviation Authority’s guidance document on airspace change, was introduced in 2018 to make the process fairer and more transparent, and to provide the opportunity for adequate engagement with local communities and other stakeholders impacted by airspace changes. I say that in reference to the third point that the hon. Member for Edinburgh West asked me about. The process rightly continues to be kept under review. Given the implications that airspace changes can have for safety, security and the environment, it is necessary for the programme to be subject to robust and transparent procedures.

The airspace modernisation strategy underpins the future development of the UK’s aviation sector. It provides clear direction on how to bring our ageing legacy airspace design up to date, and how to take it into the future, for modern aircraft and technology. On the future airspace strategy implementation, one of the most complex and pressing aspects of airspace modernisation is the need to redesign outdated flightpaths to and from our airports. The future airspace strategy implementation programme is a fundamental component of the airspace modernisation strategy. FASI is a UK-wide upgrade of terminal airspace, involving our 22 airports. The work to co-ordinate a more efficient airspace system is being done in collaboration with the Airspace Change Organising Group and National Air Traffic Services. Earlier this year, the Civil Aviation Authority accepted the second iteration of the Airspace Change Organising Group’s master plan for UK airspace change proposals in the airspace modernisation strategy.

On the hon. Lady’s second point, there is Government funding of £9.2 million to support these proposals and continue this important work. Edinburgh airport, which is in her Constituency, received £484,500 of Government funding through the programme. The funding allows airports to remain in the FASI programme, and I am pleased to say that much progress has been made under that initiative.

Fortunately, the aviation industry is recovering. This year, traffic levels returned to 85% of pre-covid traffic, and some airports forecast that growth will exceed 2019 levels in just a few years’ time. It is therefore only right that we return to the “user pays” model, under which airports fund the modernisation of their airspace. Those costs may be passed on to customer airlines, but it will ultimately be the passengers who benefit from the changes through quicker, quieter and cleaner journeys.
