Heathrow: Noise Mitigation

Ruth Cadbury Excerpts

Monday 19th October 2015 Commons Chamber

[Dr Lee]

I would argue that it can be mitigated—there are different things that I will come to—but I recognise that the frequency of flights has increased. The types of aircraft are important in terms of where they fly and how high they are in the sky.

Dealing with arrivals will require more action. I was surprised to learn through correspondence with the Minister that NATS prioritises noise mitigation only for flight path designs up to 4,000 feet. The Minister goes on to say in the next sentence of his letter that flight path designs up to 7,000 feet are being considered too. Which measure does he favour? Seven thousand feet would be better for my constituents.

To further deal with noise from arrivals, I would like to see a clear definition of the continuous descent approach that would require a greater adherence to the 3° path from 8,000 feet down and not just at 4,000 feet, when NATS at Heathrow takes over. This would raise the height of planes above my constituency.

[Ruth Cadbury (Brentford and Isleworth) (Lab)]

I very much appreciate the hon. Gentleman’s introducing this debate. My constituency is also significantly affected by noise from Heathrow. I welcome the opportunity to hear what happens in his constituency when flight paths are changed. Is he aware that in my constituency there can be no variation of landing paths because all planes are locked into the landing arrangements at Heathrow and for 70% of the time planes are flying over a built-up area all the way from Kew to the runway?

[Dr Lee]

Clearly, for the constituencies close to the airport, mitigating noise becomes difficult. The glide approach, with an aircraft using engines less, would be quieter, even in the hon. Lady’s constituency. Some changes can be made. I am realistic enough to know that the constituencies in close proximity to Heathrow will be impacted to some degree, but the impact could be less if we gave some consideration to these suggestions.

[Dr Lee]

As the hon. Gentleman knows, I will be passing through Belfast airport soon, and I shall be able to admire the country that he has the privilege to represent a part of.

As I said, I would like to see a clear definition of the continuous descent approach that would require a greater adherence to the 3° path from 8,000 feet down and not just at 4,000 feet, when NATS at Heathrow takes over. This would raise the height of planes above the constituency. Planes are noisiest when there is a faster level of negative vertical speed. Furthermore, I have concerns about arrivals that have not been stacked or that come out of the Ockham or Biggin stack at 8,000 feet and have to descend to about 4,000 feet for their final approach. If NATS were mandated to take noise mitigation seriously, that would become much less of an issue for residents on the ground.

Another area with scope for improvement is the way in which certain noisy aircraft are dealt with. Has the Department for Transport considered banning such aircraft from taking off and landing between 9.30 pm and 7.30 am? The retrofitting of noise-reducing devices to Airbus A320s is being actively encouraged by Heathrow, but about 20% of A320s operating at Heathrow have yet to have them installed. Will the Department issue guidance on this? One airline operating a few A320s without the retrofit can have a huge noise impact.

With old planes, as they get sold on and have a life of 30 years or more, a ban might be the only way to actually get them retired from service. That is particularly applicable to new, low-cost, long-haul carriers. In addition, aircraft manufacturers could do a great deal more: no manufacturer offers streamlining for its landing gears, for example. Manufacturers could also modify their advice for airlines on operating techniques to reduce noise, including additional use of speed brakes located on the upper side of aircraft, which, if used instead of flaps, would further reduce noise.

I very much hope that the Minister will be able to bring about a resolution to at least some of the problems I have outlined. It is quite easy, as Members can tell, to get bogged down in the detail of the issue, but the best solution most certainly involves a far more robust mandate for NATS or, perhaps, the Civil Aviation Authority.

I have long been a proponent of Heathrow expansion, primarily based on the economic benefits it would bring for my constituency of Bracknell and the Thames valley region, and on its wider implications for the UK’s long-term prosperity. Heathrow expansion offers the best prospects for stimulating the local economy by supporting and creating jobs. An expanded Heathrow would also play an important role in the continued economic success of the Thames valley, ensuring that it retained its position as a hub of innovation, productivity and prosperity.

I am determined, however, that current usage of Heathrow airport, and any future expansion, should not come at the expense of the health and wellbeing of local communities. In particular, when Heathrow is on easterly operations, some residents in the Thames valley can be blighted by aircraft noise for up to 19 hours a day. That has happened a lot recently.

[Dr Lee]

If the hon. Lady will forgive me, I will make progress.

As outlined earlier, the situation has been further exacerbated by the changes implemented by NATS, which narrowed the Compton departure route corridor, resulting in greater concentration of aircraft activity over densely populated areas in my constituency.

Over the past year, I have held regular meetings with Heathrow executives, held a public constituency meeting following NATS flight trials, and made representations to Heathrow Airport Ltd, NATS and the CAA. During this time, it has become clear to me that much more attention needs to be paid to the mitigation of noise and that a relevant body should be made statutorily responsible for its reduction. NATS, which controls the airspace around Heathrow, currently has no responsibility for mitigating aircraft noise that could affect hundreds of thousands of people.

As I have said, there are many issues at play, including old aircraft and poor piloting, but in the short term NATS could do the most to alleviate the issue, particularly around Heathrow, where it vectors the aircraft much too far from the airport, which subjects many more communities than necessary to excessive noise.

As I have outlined, there are solutions to mitigating noise around Heathrow. The Government should seriously consider them, as I believe that the UK’s future as a trading nation and tourist destination depends on our ability to meet the increasing demand for airport capacity. For the good of the country, we have to move forward and build the airport capacity that Britain needs. Over the coming years, I will continue to campaign on behalf of my constituency to ensure that Heathrow can increase its capacity. But rest assured that I will also campaign vigorously to mitigate the impact of excessive noise on my constituents’ lives.

[The Parliamentary Under-Secretary of State for Transport (Mr Robert Goodwill)]

I congratulate my hon. Friend the Member for Bracknell (Dr Lee) on securing this debate on the mitigation of noise around Heathrow airport. I thank other colleagues for their contributions and for the way in which they have described the problems that aircraft in the air cause for people on the ground.

I assure the House that the Government are acutely aware that noise is a major environmental concern around airports, and especially for the communities surrounding Heathrow. I remind the House that, as is set out in the aviation policy framework that was published in 2013, our overall policy is to limit and, when possible, reduce the number of people in the UK who are significantly affected by aircraft noise. That remains our overarching policy, and the aviation industry is fully aware of it.

[Ruth Cadbury]

Is the Minister aware that 300,000 people who are not currently overflown by flights into Heathrow will be affected severely if runway three goes ahead? The third of my constituency that is not currently overflown by landing paths into Heathrow will be directly underneath the new flightpaths. Those people did not know that they would be living in such a noisy environment when they bought their homes. Does the Minister agree that that is not fair and that runway three should not be imposed on those 300,000 people in London and beyond?

[Mr Goodwill]

May I reassure the hon. Lady that although the Airports Commission has made its report, the Government are yet to make a decision on it? We hope to do so by the end of the year.

--- Later in debate ---

[Mr Goodwill]

I ought to make some progress as time is fairly limited and I want to answer some of the points that have been made in the debate.

In the case of Heathrow, the airport, the CAA, the airlines and NATS are aware that noise is a significant concern for the communities around the airport that needs to be acted on. Heathrow is taking steps to cut back and mitigate its noise impact. Under the European Union’s environmental noise directive, it is required to produce a noise action plan that sets out its intentions to mitigate noise.

The House will be interested to know that last year the airport published its “Blueprint for noise reduction”, setting out 10 practical steps that it is taking to mitigate noise in 2015. Earlier this year the airport also established the Heathrow community noise forum, which is made up of representatives from local authorities around Heathrow—including that in the constituency of my hon. Friend the Member for Bracknell—as well as representatives from NATS, British Airways, the Department for Transport and the CAA. One of its principal aims is to help to build trust with local communities—I know that that trust has been tested—by keeping them informed of developments, and seeking to improve the overall level of understanding about Heathrow’s operations and airspace. That good initiative by the airport will bring about real benefits.

Under powers set out in the Civil Aviation Act 1982, the Government set noise controls at Heathrow, including restrictions on the number of flights allowed during the night, and specified the routes that departing aircraft need to follow. The controls also cover minimum height levels and maximum noise limits that departing aircraft must adhere to at certain points near the airport. Communities can be affected by noise disturbance from either arriving or departing aircraft—or indeed both—but, as I will set out, it is more difficult to lay down limits for arrival aircraft.

The routes used by aircraft and the height at which they fly are significant factors that affect the noise experienced by people on the ground. The departure trials last year at Heathrow and Gatwick, and the public response to them, as indicated by the number of complaints received, clearly show that people notice changes in airspace use and—as my inbox would attest—are quick to make their feelings known.

The Government understand communities’ concerns and are considering how the airspace change process can be improved. The CAA is also aware of concerns about the airspace change process and is carrying out an independent review into whether that can be improved. I assure the House that those trials ended last year, and the information gained is vital to increase our knowledge for future airspace change driven by the CAA’s future airspace strategy.

Changes to the UK’s airspace structure are required, which we must accept while we are seeking to address the impact of such changes as much as practicable. Aviation is a success story, and the public like the opportunity that it affords for holidays or to meet family and friends living far away, as well as for business travel, which is vital for our economy. However, the basic structure of UK airspace was developed more than 40 years ago, since when there has been a dramatic increase in demand for flights. The future airspace strategy is critical to ensuring that the industry is efficient and able to minimise its overall environmental impact.

[Ruth Cadbury]

When considering the implications and impact of aviation on communities affected by noisy environments, will the Minister also consider the impact of sleep deprivation and that on children’s learning in schools when their classrooms are overflown every 60 to 90 seconds?
