Blog by John Stewart: Can a Four Runway Heathrow Really be Quieter?
In an interesting and detailed blog, John Stewart (Chair of HACAN) sets out what the effect will be of having a 4 runway Heathrow, as proposed by the Policy Exchange last year. Their plan is for 4 runways parallel, some 3.9 kilometres further west than the current runways, all of which could work at once. And they claim this will cause less aircraft noise for Londoners. John assesses this claim, and finds that the plan envisages up to 960,000 planes per year (cf. 480,000 now) and there would be no rest periods for Londoners during the day. Though the plan is for there to be no night flights, and for smaller planes to come in to land over London at higher altitudes due to a steeper glideslope, there is not likely to be an improvement in the noise experienced. Though smaller planes may be able to come in at a 5 degree glideslope, the noisier planes will have to continue on a 3 degree approach. What thousands of Londoners want is runway alternation and respite periods. They will not get these from the Policy Exchange proposal.

Concern in boroughs near Heathrow about aircraft noise threat from new runways
The flight paths, and areas to be affected by aircraft noise if Heathrow was allowed to build a 3rd and even a 4th runway were revealed earlier this week by the 2M group. People in Richmond are very concerned about the even greater noise intrusion into their lives that would be caused. A Richmond Cabinet member said Heathrow expansion would make cause blight to spread to parts of the borough that are currently less affected whilst increasing the disruption for those who already suffer the burden of continual aircraft noise. Residents in Surbiton are also very concerned that their area may suffer from a large degree of noise. One resident said it would probably force her to move out of the area, and "It is greed, it is capitalism. I care greatly about the environment and we are already wrecking what we have got.” Another said the plane noise puts him off living in the area. Richmond are holding a referendum in May, as are Hillingdon and Hounslow councils, to show the Airports Commission and the industry that Heathrow is not an acceptable location for expansion.

New flight path maps from 2M, for 3rd and 4th Heathrow runways, show huge areas and up to 3 million people affected by noise
The 2M group, which represents some 24 local councils and between them some 3 million people, have released likely flight path maps for 3rd and 4th Heathrow runways. 2M estimate that while some 1 million people are affected by Heathrow noise at present, with 2 more runways, that would rise to 3 million people. Their indicative flight paths for arrivals and departures show the large areas which would be affected by aircraft noise if a northern and a southern runway were to be built . The approach across London to a northern runway would cover Mayfair, Belgravia, Sloane Square, South Kensington, Earl’s Court, West Kensington, Hammersmith, Chiswick and Brent. That would include all these parks (which cannot be soundproofed): Hyde Park, Regent’s Park, St James’s Park and Kensington Gardens. The areas which would be affected by approaches to a southern runway would be Streatham, Balham, Tooting, Wandsworth Common, Earlsfield, Southfields, Putney Heath, Roehampton, Richmond Park, Richmond town centre, Isleworth, Hounslow Heath and Bedfont. The leader of Wandsworth Council commenting on blighting the lives of 3 million people and spoiling the quiet enjoyment of huge parts of London: "The price is far too high and the benefits far from certain.” This will definitely be a key political issue at the next election.

Hale releases damning analysis of Luton Airport noise track record
Opponents of expansion at Luton (HALE) have released a damning analysis of the noise track record at Luton Airport over the past 5 years. The airport has just produced a 5 page Noise Fact Sheet, which claims that though it had a 23% increase in aircraft movements between 2011 and 2012 there was a huge reduction in the very noisiest planes. This is distorting reality, as the Fact Sheet does not properly deal with noise from other flights. HALE highlights that the Airport’s claims are entirely misleading because they are not based on a statistically representative sample of the data. It has found that in reality on average flights are getting noisier over time, not quieter, with 60% of daytime departures now registering at or above the 73dB annoyance level when they reach the noise monitors 4 miles from the airport, compared to 45% in 2007. Night flights are louder too. The airport is planning to add 60% more flights, taking the average daily total from 270 to 430; many of these would be clustered in the peak early morning and late evening periods, resulting in a doubling of flights between 10pm and midnight.

Heathrow noise ‘hinders pupils’ reading progress’
Children living under the Heathrow flight path are suffering two-month lags in their reading development as a result of aircraft noise. Hounslow council says pupils in the borough have to put up with “continual disruption”, and warned the problem will worsen if the airport expands to three or more runways. Around 40 schools are directly under the Heathrow flight paths with planes landing every 90 seconds or so much of the day. The council cites an international study by London University into aircraft noise which found it led to a “significant impairment” in reading development, as well as affecting long-term memory and motivation. As well as a 2-month delay in reading, the children's education is suffering from the continual disruption from low-flying jets. If schools don't have triple glazing the interruptions to lessons can be relentless. One school near the airport has had shelters installed in the playground so children can escape the noise. A 2010 ECRD study suggested that chronic aircraft noise has a deleterious effect on memory, sustained attention, reading comprehension and reading ability.

Pakistan International Airlines has still not switched to less noisy planes for Leeds Bradford night flights
Pakistan International Airlines (PIA) have repeatedly broken noise limits at Leeds Bradford airport, and it is meant to have changed to less noisy planes. However, the introduction of these planes has been postponed. PIA is meant to have switched to Boeing 777s on its services to Islamabad from earlier in March. There have been 8 breaches of night time rules over the previous 12 months. Two years earlier the council had served a breach of condition notice on the airport. Improvements were made but after a further eight breaches councillors said they wanted a commitment on timescale. Earlier councillors had agreed to support the approach of continued dialogue rather than formal action.

Fantastic demonstration in Luton against night flights
Dozens of campaigners concerned about the proposed doubling of night flights at Luton airport rallied at Luton Town Hall and handed in a 1,000-signature petition calling for planning controls to limit any further increase in night noise and disturbance to people’s sleep. The event was a huge success and shows just what people power can do. To the chant of “What do we want? No More Night Flights! How do we get it? Planning Controls!” the protestors made the point that Luton Borough Council needs to act responsibly in order to limit the continued growth of an airport which campaigners claim is in the wrong place for any further expansion. The airport wants to almost double the number of passengers, up to 18 million per year, and has set such a high night noise quote and noise cap that it could double its night flights to 16,000 per year and still be within its so-called limits.

Possibility of more night flights to Heathrow over Windsor rather than West London
Plans drawn up by the DfT could see hundreds of night flights diverted away from the homes of 110,000 residents of the west London areas like Richmond, Kew and Hounslow, over the Windsor area. There could be an extra 1,500 - 1,700 night flights per year over Windsor, starting at 4am. About 90% of the flights at night are between 4.30am and 6.00am, waking people up and making it difficult to many to get back to sleep. The local MP for Windsor, Adam Afriyie, is concerned on the negative impact the change would have on the quality of life of his constituents. The Queen often spends weekends at Windsor, and also many weeks during the year. Under existing rules Heathrow is allowed 5,256 incoming scheduled night flights a year, so Londoners have to put up with around 16 planes overhead every night. Due to the wind direction, about 72% of the time they come from the east over London. The DfT is now considering ordering pilots to approach from the west unless a tailwind of five knots or more makes this impractical. This is part of the current night flights consultation, which closes on 22nd April.

Heathrow night flights are “inhumane” and the airport is urged to stop them
There is pressure on the management of Heathrow to justify the use of night flights. This has been discussed at the London Assembly's environment committee. There are some 15 flights that land at Heathrow between 11.30pm and 6am every day and which activists say have an impact on 100,000 West Londoners. For many people the first plane coming in at 4.30am is their alarm clock. As well as campaigners against Heathrow's expansion, senior local council executives say the flights are “inhuman” and there is an economic cost to sleep deprivation. Colin Ellar, deputy leader of Hounslow Council, said "even a quiet airplane is very noisy. It will wake you up when it’s still dark, you might get back to sleep, you might not.” “I’d say it’s the equivalent of a lorry coming and revving its engine just outside your bedroom window several times a night,” Heathrow say night flights boost the economy by £340m a year and by 6,600 jobs (evidence for that?)

Sleep deprivation causes adverse effects on health due to disruption of gene activity
Sleep scientists at the University of Surrey have found that sleep deprivation affects hundreds of genes involved with inflammation, immunity and cells' response to stress. This might help explain why some people who do not get enough sleep have an increased risk for obesity, heart disease and cognitive impairment. Researchers took whole-blood RNA samples from 26 participants after they had spent a week sleeping 8.5 hours a night, and the same participants after a week of sleeping for just 5.7 hours. That amount of sleep is not unusual for many people, and an estimate from the USA is that perhaps 30% of American adults sleep for under 6 hours. (The study did not look at sleep disturbance, as is the case for aircraft noise). The study found genes related to circadian rhythms, metabolism, inflammation, immune response and stress were all affected by the experiment. Some were more active, and some less, during sleep deprivation. Other studies have found lack of sleep increases the risk of obesity and type II diabetes. It can affect blood sugar levels, and hormones that control appetite. There are also effects on hypertension, elevated risk of stroke and of heart disease.
