Night Flights: Impact on Communities

Debate between Sarah Olney and Richard Holden

Tuesday 8th November 2022 Commons Chamber

[Mr Holden]

My understanding is that the statistics from the York Aviation report in 2021 on the economic impact of night flights in the UK said that it was about £8.7 billion of gross value added to the UK economy, with tens of thousands of jobs supported in the UK.

The time differences of an interconnected global transport system, particularly with the far east, mean that it is difficult to avoid all flights at night and early in the morning. As I said, the recent research from York Aviation estimates that in 2019, flights during the night quota period had a total impact of over £8 billion. Heathrow airport accounts for a significant proportion of that value. However, we also recognise that the noise from aircraft at night brings significant negative impacts to the local community. As the hon. Member for Richmond Park made clear, exposure to aviation noise at night can impact on physical and mental wellbeing, and I agree with her that sleep disturbance can have a negative impact on health, increasing the risk of daytime sleepiness, hypertension and cardiovascular disease.

We need to strike a fair balance between the positive and negative impacts of night flights. With that in mind, for several decades the Government have set noise controls, including restrictions on night operations at Heathrow, Gatwick and Stansted. Those airports are designated for noise purposes under the Civil Aviation Act 1982. That reflects their strategic importance and the need to balance the impact on communities with the impact on the UK economy and jobs. At other airports, noise controls are best set locally, and there are regulations in the devolved Administrations enabling them to look at some of the environmental impacts.

Last year, we consulted on night flight restrictions at the designated airports and on a night new night flight regime. Following that consultation, we announced that existing night flight restrictions at Heathrow, Gatwick and Stansted will be rolled over for three years. That will allow the Government to develop a more meaningful evaluation of the cost—which the hon. Lady asked for—and of the benefits of night flights, taking into account the effects of the pandemic and the extent and speed at which aviation demand returns.

[Sarah Olney]

You talk there about a full analysis. I just wonder whether you can confirm that that will include—

[Sarah Olney]

I beg your pardon, Madam Deputy Speaker. I wonder whether the Minister can confirm that that will be a full analysis of the health and mental wellbeing impacts and of all the other things we have been talking about today.

[Mr Holden]

I thank the hon. Lady for that point, and I will address that exact issue later in my speech.

As the hon. Lady said, the night flight regime is now in place until October 2025, and we intend to consult in late 2023 on proposals for the next regime. I urge hon. Members who are interested in this issue to take part in that consultation, and I look forward to the hon. Lady’s feelings and those of her constituents being made known.

The night flight regime limits the number of flights for the purpose of noise management. The restrictions significantly reduce the number of flights that would otherwise operate because of the quota. At Heathrow, the number of movements permitted has not changed for many years. Although I admit that there are occasional extra flights, they are not something that the Government want to see expand in the future.

The new generation of aircraft, such as the A350 and the Boeing 737 MAX, have a significantly smaller noise footprint on departure and on arrival—it is about 50% smaller on departure and 30% smaller on arrival—than the aircraft they are replacing.

[Mr Holden]

I am sorry, but I have to get through my speech.

Overall, aircraft noise is expected to continue to fall in the future. The last consultation on night flight restrictions did implement a ban on QC4-rated aircraft movements at the designated airports during the night-time quota period to specifically address some of the noise concerns. Prior to the pandemic, departing Boeing 747-400s were the noisiest aircraft in regular service at those airports. Although they could not be scheduled during the night quota period, they could still operate if delayed, although there were only very few of those delays. The operational ban on QC4-rated movements came into effect for the most noisy aircraft at the end of last month for the winter 2022-23 season. It will help in limiting the number of people significantly affected by aircraft noise by preventing those aircraft from operating.

On the dispensations, I know that Heathrow would be keen to meet the hon. Lady and other colleagues to discuss the issue further. I am aware of the issue she raises. Section 78 of the Civil Aviation Act 1982 sets the legal framework through which the Government set the night flight operating restrictions at the designated airports. That allows the airport operator, or the Secretary of State for Transport, to disregard certain movements, providing that they meet specific criteria. Those dispensations are granted by the Secretary of State and include flights by senior members of the royal family, UK Government Ministers or Heads of State on official visits. Humanitarian relief flights or exceptional circumstances could also be covered. Dispensations under a notice granted by an airport manager, which would include emergencies where there is immediate danger to life or health, are also included, as are delays as a result of disruption that lead to serious hardship and major congestion at an airfield or terminal.

This summer was particularly challenging from an air traffic control perspective and resulted in an increase in late-running flights. Widespread and prolonged air traffic disruption accounts for the majority of the 415 flights that the hon. Lady mentioned, which qualified for a dispensation at Heathrow. Any movements that are granted a dispensation in this way do not count towards an airport’s movement allowance. I appreciate that that creates uncertainty about the night flights that communities can expect.

[Sarah Olney]

It is very kind of the Minister to give way again. Will he elaborate slightly on some of those numbers and whether it might be possible for members of the public and Members of Parliament to get a better understanding of when dispensations have been granted?

[Sarah Olney]

And also why, because they have no visibility, which makes it very hard for us.

[Mr Holden]

I fully take on board the hon. Lady’s points and would recommend that she takes up the opportunity to meet with Heathrow officials, who have offered to meet her, because they will be able to explain in full detail. If she wants to write to me after that meeting, I will obviously write back with as many details as I have in the Department.

We remain committed to revising our night flight dispensation guidance—perhaps the hon. Lady can also write to me about that after those meetings. This will be done following a review of the number of night flight dispensations made this summer, because it was higher. I would like to reassure the hon. Lady that all night flight dispensations granted by airport managers are subject to monitoring by the Department for Transport.

To respond to the issues the hon. Lady raised about night flights, there is a study currently under way. Exposure to aviation noise at night can impact on physical and mental wellbeing, as well as sleep disturbance. To better understand this, the Department has commissioned the aviation night noise effects study to examine the relationship between aviation noise and sleep disturbance and annoyance, and how this varies by different times of the night. The study is a collaboration between St George’s University of London, NatCen Social Research, Noise Consultants Ltd and the University of Pennsylvania. It is the first study of aviation noise effects on sleep disturbance in the UK for 30 years. The first stage of ANNE will involve a cross-section of 4,000 people who live near eight of the major UK airports, to assess the association between aircraft noise exposure at night and subjective assessments of sleep quality and annoyance.
