I will come to that, and I look forward to meeting the hon. Member, because I would like to have a safe cycle ride around Richmond Park one of these days. I will be raising that with the constituency MP, and I think it could help with climate mitigation and climate change. I look forward to her views on that.
As I have acknowledged, noise from aircraft, particularly at night, impacts on local communities. At the same time, night flights are also a vital part of global aviation and provide significant economic benefit, not just to the capital city but, as we know, to the whole of the UK. The whole UK relies on Heathrow as our only hub airport to keep the flow of people, goods and services moving, supporting thousands of jobs as a result. With that in mind, for several decades the Government have set out noise controls, including restrictions on night operations at Heathrow, Gatwick and Stansted.
The House can imagine my surprise, on becoming the new Minister, to realise that I had direct powers over the south-east three, and no powers over the rest of the nation. That will hopefully change in the years to come. Those airports are designated for noise purposes under the Civil Aviation Act 1982. That control reflects the need to balance the impacts on communities with the benefits to the UK economy. We also know that Heathrow is one of our major hub airports for cargo and freight to keep this country fuelled, supplied and fed. At other airports, the noise controls are set by local ordinance and local competent planning authorities.
The current night-flight regime limits the number of flights for the purpose of noise management. The night-flight restrictions significantly reduce the number of flights that could otherwise operate within the night quota period between 11.30 pm and 6 am. Earlier this year, the Department for Transport consulted on proposals for the next night-flight regime at Heathrow, Gatwick and Stansted airports, which will commence in October 2025, a year or so from now. The consultation proposes that movements and quota limits for Heathrow, Gatwick and Stansted would remain the same as now for a three-year period covering October 2025 to October 2028. That is while we await evidence that could support change in the future. I thank the hon. Member for Richmond Park for her response to the consultation, and I hope soon to be in a position to announce a decision on the next night-flight regime.
At Heathrow, the number of movements permitted in the night quota period has not changed for many years. During that time, aircraft have become quieter, as I said at the start of the speech, and the overall noise footprint of the airport has shrunk. Progress has been made. At Heathrow, for example, between 2006 and 2019, there was a reduction of 21% in the number of households exposed to aircraft noise within the London 55 dB noise contour area. The noise footprint of new-generation aircrafts, such as the Airbus A350 and the Boeing 737 MAX, is typically 50% smaller on departure and 30% smaller on arrival than the aircraft they are replacing. I talk with manufacturers all the time about the future of flight and how we can carry on reducing the noise footprint of these vehicles. Overall, noise from aircraft movements is expected to continue to fall in the future compared with today’s levels.
I will briefly touch on airspace modernisation, which is a key plank of our manifesto. It is one of our key commitments, along with sustainable aviation fuel. We have an analogue system in our skies in the UK in a digital age. The system was designed closer to the time that Yuri Gagarin went into space than today. A pilot who travelled through time, coming in the TARDIS back to the future, would still be flying the same flight paths that they would recognise from more than 60, 70 or 80 years ago. That has to change if we are to maximise the benefits to aviation and growth and the carbon reduction we could bring, if we just got the flights not to circle over the hon. Member’s constituency, but to fly in a straight line point-to-point.
