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.
