Noise - Approaching Aircraft
GACC has had several meetings with Aviation Ministers to discuss disturbance by approaching aircraft, and other noise issues. We pressed the Transport Secretary to reduce noise limits. In 2009 we organised a seminar to discuss methods of reducing disturbance by approaching aircraft. This resulted in a paper on Approach Noise which we discussed with Transport Department officials, and some of our recommendations were included in the draft aviation policy published in 2011.
In September 2011 we submitted an important Evidence Paper on Noise and Health to the Transport Department as preparation for the new White Paper.
The Noise Action Plan.
Under the EU Environmental Noise Directive Gatwick is required to produce a plan to reduce noise. We pressed in 2009 for improvements in the first Gatwick Airport Noise Action Plan. and are continuing to apply pressure on the airport (in conjunction with the local councils,through the airport noise committee) to implement the promises made in the Action Plan. See Gatwick noise committee minutes. In November 2013 Gatwick Airport suddenly produced a (slightly) revised noise action plan to run until 2018 and gave only four working days for comments. GACC obtained a longer period for comments and informed our members. We submitted this response
NOISE CONTOUR MAPS
A research study (ANASE) commissioned by the Department for Transport found that the level of annoyance is considerably higher than indicated by the leq contour maps, and that as the standard of living rises people expect to live in a quieter environment.
Gatwick Airport has announced a new noise insulation scheme (2 February 2014). It is welcome that this covers a wider area, and provides larger grants. But, of course, it does not solve the noise problem for those who like to have their windows open, or who wish to be in their garden, or who wish to visit any of the Areas of Outstanding Natural Beauty around Gatwick.
GACC will be commenting further when we see the details.
CONTINUOUS DESCENT APPROACH (CDA)
For some years the CDA procedure has been in force for aircraft arriving at Gatwick. Aircraft descend in a continuous 'glide' rather than, as previously, in a series of steps. This makes some reduction in noise, mainly from 10 – 25 miles from the airport.
Details are given in a CAA booklet.
Maximum noise limits for aircraft taking off are 94 dBA by day; 89 dBA between 2300 and 2330, and between 0600 and 0700. At night, between 1130 and 0600, the limit is 87 dBA. The noise levels are measured by noise monitors situated approximately 6.5 km from the start of take-off. There are penalties (£500, or £1,000 for a serious breach) on aircraft which exceed the limits, and these are paid into a Community Fund. But because the limits have not been reduced since before March 2002, when the noisy Chapter 2 aircraft were banned, few aircraft now exceed the limits. There are no limits on noise caused by aircraft on approach.
GACC has pressed the Department for Transport to reduce the noise limits, and a reduction was contained in the Draft Aviation Policy Framework. but no action has been taken. In the 1990’s GACC campaigned for noise limits to be imposed on aircraft when landing, as for taking-off. This was subject to a major study by the Department for Transport with ten noise monitors deployed between Gatwick and Tunbridge Wells. But in the end objections from the airlines killed off the idea. GACC has pressed the Department to re-consider the scheme based on the annual average performance of each airline.
According to the Department for Transport, aircraft departing from Gatwick in 2005 emitted 4.4 million tonnes of CO2. The latest DfT forecast is for 3.8 million tonnes in 2030 This makes it one of the most CO2 producing sites in the South East.

The Climate Change Act 2008 set a target to reduce UK domestic greenhouse gas emissions - excluding aviation - by 80% below 1990 levels by 2050. The official Climate Change Committee, charged with implementing the Act, has set a target for the aviation industry - to reduce aircraft CO2 emissions to 2005 levels by 2050. They have stated that demand for air travel will need to be limited to an increase of 60%, and the increase in flights to 55%. Even if aviation emissions are reduced to 2005 levels by 2050, the rest of industry will have to make cuts of 85%.
The noisiest types of aircraft are banned between 11.00 pm and 7.00 am. The number of flights between 11.30 pm and 6.00 am is limited by a quota - at present 11,200 in the summer (seven months) and 3,250 in winter.
There is also a separate quota system based on noise, with noisy aircraft using more points. Aircraft are classified as QC1, QC2, QC4 etc. A QC4 aircraft uses four points and makes twice as much noise as a QC2. A QC2 uses two points and makes twice as much noise as a QC1. There has been a change in classification which makes it difficult to compare past and future figures.
The Government has carried out one consultation on the system for controlling night flights. They have now proposed to make virtually no changes until 2017 - see Latest News.
In 2006 the Government announced its decision on the number of night flights from Gatwick for the six years 2007 - 2012. The number of night flights remained at roughly the previous level but there was a gradual 10% reduction in the amount of noise permitted at night. The noisiest aircraft were banned (except when delayed). GACC welcomed this small improvement. GACC press release
Gatwick has more night flights than Stansted, and twice as many as Heathrow. The total level of noise permitted at night each year at Gatwick is greater than at Stansted but less than at Heathrow.
PEACE and QUIET'
As a result of the eruption of the Eyjafjallajokull volcano in April 2010 peace and quiet descended on the Gatwick area for six days. GACC undertook a survey of public reactions. Impressions of Silence.
The most serious threat to the health of local residents, particularly those suffering from respiratory problems such as bronchitis or asthma, is NO2. Reigate and Banstead Borough Council have expressed concern that in parts of Horley pollution levels are only slightly below EU limits - which became legally binding in 2010.

With an average of around 80,000 passengers a day, and around 21,000 employees on airport, Gatwick generates a large volume of road traffic. This adds to congestion on the M25, and is particularly serious on the rural roads east and west of the airport. It also adds to local pollution.
For many years the airport has had a target that 40% of passengers should arrive or depart by public transport (to reduce pollution and pressure on the road system). The target was achieved for the first time in 2010. The proportion of staff traveling by public transport has increased as a result of the new Fastway bus system but is still only about 25%
