Noise Management Scheme

LONDON CITY's latest Noise Management Scheme was approved by the local planning authority (the London Borough of Newham - LBN) at a meeting on 28th April 1999. Click here to see a copy of the scheme as well as the report received by LBN members about it.

The Scheme includes a number of new features:

  • A new combined noise monitoring and track keeping system. This links the present noise monitoring system with the Airport's radar facilities. It allows deviations from standard routes used by aircraft to be identified and provides a continued facility for the verification of the noise contours. This system has now been installed and is in the final stages of testing and validation.  Click the icon to the right to see plot taken from the system. The yellow tracks are inbound flights and those in red the tracks of departing aircraft
  • The introduction of additional fixed power supplies for aircraft on the apron thus obviating the use auxiliary power units unless it can be demonstrated to the local planning authority that this is operationally necessary.
  • A scheme aimed at minimising the noise impact of engine running on the ground in connection with routine daily aircraft operations. This  complements new arrangements to restrict ground running for test or maintenance purposes (see below).
  • A system of operational and financial incentives and/or penalties aimed at securing compliance with the various measures for the control of noise and good track keeping. The value of these incentives/penalties have still to be agreed between the Airport and the LBN. 
  • The continued maintenance of a record of the numbers and types of aircraft which land and take off at the Airport every day.
  • Regular meetings with the local planning authority, the Airport Consultative Committee (ACC) and other bodies for the review of the scheme. The ACC receives reports on the operation of the Noise Management Scheme at least twice a year.

Permitted Aircraft

AIRCRAFT are not permitted to use the Airport unless they fit into one of the following noise categories:

Category

Noise Reference Level (PNdB)

Noise Factor

A 91.6 - 94.5 1.26
B 89.6 - 91.5 0.63
C 85.6 - 88.5 0.31
D 82.6 - 85.5 0.16
E Less than 82.6 0.08

 

Aircraft new to the Airport are allocated a provisional category following monitored trial flights at the Airport. This has to be approved by the local planning authority. All flights from the Airport are monitored and the category of each aircraft type is reviewed annually (between March and May) in the light of data from the noise monitors. Depending on the results of the review the category allocated to an aircraft may be changed. The aircraft categories are linked to Noise Factors which are used in calculating the number of flights against the permitted numbers, i.e. noisier aircraft count as more than one movement while the quieter types count as less than one - see our About the Airport page for details.

Fokker 50

Aircraft must also be capable of making an approach at 5.5 degrees or steeper - this compares with 3 degrees at most other airports. Helicopters and other vertical take off and landing (VTOL) aircraft, and aircraft with a single engine, are not permitted and flying for club or leisure purposes is prohibited.

Annual Noise Contour

The noise monitoring arrangements requires the Airport each year to calculate and supply to the London Borough of Newham and the Consultative Committee the Summer 57 LAeq, 16 Hour, Noise Contour - see the panel below for details. The annual contour is published on this site - latest available is that for the Summer of 2006:

Noise Monitoring System

THE Noise Management Scheme, which has operated since 1990, depends on fixed monitors located a short distance outside the Airport's boundaries to the east and west. In the new Noise Management Scheme they are used:

  • To establish the provisional noise category of new aircraft using the Airport.
  • For the annual review of aircraft noise categories.
  • To produce each year the 57 LAeq16hour noise contour.

The 57 LAeq, 16 Hour, Noise Contour

This is currently used by the Government as an indicator of the "onset of significnt community disturbance".  The contour relates to the average daily aircraft movements over the three month period 16 June to 15 September during the 16 hours period from 0700 to 2300 hours. 

The index used in calculating the contour incorporates an "energy averaging" of sound.  This is sometimes criticised because it is said it does not reflect people's experience of specific noise events.

On 8th May 2001 the Aviation Minister announced a new three year Noise study including the relationship between noise levels and annoyance. This study is still in progress (July 2007)

Sound Insulation Scheme

THE trigger point for sound insulation and mechanical ventilation for homes and noise sensitive premises is the Airport's 57LAeq 16 hour noise contour - see the panel to the right for more information. This is a much lower trigger level than that which operates at most other UK Airports with noise insulation schemes. The Summer 2006 contour for London City Airport is shown on the Map (551kb) 

Note: The contour is shown at a higher resolution on the attached Acrobat .pdf file (2.02 mb) **. This file is best viewed in the Reader at 300% or 400%.

The specification of the sound insulation and mechanical ventilation provided under the scheme is defined in detail in the Agreement under s.106 of the Town and Country Planning Act 1990 between the London Borough of Newham and the Airport on 21st July 1998.

The first homes to be insulated were those in Silvertown immediately adjoining the Airport in Camel Road and parts of Drew Road and Parker Street. Parts of the Drew Road School were also treated. Part I of the original programme was subsequently implemented involving more properties in Drew Road and Parker Street and others in Wythes Road, Saville Road and Leonard Street. The remaining parts of the original scheme were then incorporated into a revised programme defined in the 1998 Agreement as follows:

  1. The original homes to be offered insulation of their south facing rooms and a check to ensure that they meet the acoustic standards which now apply.
  2. Homes already insulated in Part I to be offered checks to ensure that they still meet the acoustic standards which now apply.
  3. The homes and noise sensitive community buildings listed in Parts II and III of the scheme, all in North Woolwich and Silvertown, were now to be insulated. 
  4. The homes and noise sensitive community buildings in each of the four phases of Part IV of the scheme to be offered insulation as and when the 57LAeq 16 hour contour reaches the first of the homes in that phase. Part IV will extend the scheme into West Silvertown and Cyprus as well as North Woolwich and Silvertown.
  5. Where the listed homes (or noise sensitive community buildings) were built or given planning permission after 30 July 1990 they will not be eligible for noise insulation where this was required to be installed by statute or as a condition of planning permission. The premises may, however, be eligible for mechanical ventilation.
  6. The list of homes and noise sensitive community buildings is not exclusive. Other such premises, existing or which have planning permission as at 21st July 1998, will be offered insulation where it is demonstrated that they are within the 57LAeq 16 hour noise contour. However, they will not be eligible for sound insulation where this was required to be installed by statute or as a condition of planning permission. The premises may, however, be eligible for mechanical ventilation.
  7. Sound insulation to be provided in those rooms on the second and top floors, and at roof level, of the old Drew Road School (now demolished to make way for the DLR) which had been, or were to be, returned to educational use. The original noise protection measures at the school were to be checked and faults rectified.
  8. The Storey Road School  to be provided with noise protection if in consequence of noise monitoring and calculation this is shown to be necessary to bring the school up to the 1997 Environmental Design Guidelines for schools.
  9. If requested by the London Borough of Newham (LBN), the Airport to provide both the Drew Road and Storey Road schools with a conservatory or other improvements to an equivalent value.
  10. The new Britannia Village primary school at West Silvertown to be provided with further noise protection measures if this is necessary to bring the building within the 1997 Design Guidelines.
  11. Where premises are already provided with secondary or double glazing which provides the specified level of protection, or where its provision is already contractually committed, the Airport to make a financial contribution equal to the amount it would have spent in providing insulation (i.e. secondary glazing) itself. Such premises still to be entitled to mechanical ventilation.

The Committee receives regular reports on the implementation of this programme - to see these reports please refer to Committee's minutes

Although it was planned to be delivered in four separate phases Part IV of the Sound Insulation Programme will in fact be delivered as a single project. Survey work started in May 2004. This is expected to take up most of the rest of the year although some installation work can also be expected. Attached is a leaflet being used by the Airport to tell affected residents about the scheme. There is a working list of the properties covered by the scheme on our Insulation Programme page.  Managing the scheme for the Airport are Banks Wood and Parners.  The contact is David Chester on 01277 262870.

It should be noted that many of the listed properties, notably in West Silvertown, were built or given planning permission after 30 July 1990 and - see Note 4 above - will not, therefore, be eligible for sound insulation if this was required to be installed by statute or as a condition of planning permission. The premises may, however, be eligible for mechanical ventilation.

Most of the rest of the work described above was carried out in implementing Parts II and III of the programme which were substantially completed by the Spring of 2002.  In some instances it proved impossible to obtain a response from the owner and in others the owner refused treatment.  These properties are now being dealt with on an ad hoc basis as and when the owner makes contact. 

The original Drew Road school building has now been demolished to make way for the Airport Extension of the DLR.  The school is now housed in new premises built on a site nearby.

Hours of Opening

TO avoid noise for residents at night and at weekends and on Bank Holidays there are restrictions on the hours during which the Airport may be used for flights - see our About the Airport page for details.

Top of Page

Restrictions on Number of Flights

FOR the same reason there are also detailed restrictions on the number of flights - again see our About the Airport page for details.

TOP

Noise Barriers

A number of noise barriers were provided when the Airport was first developed and these will be maintained. The pier used by passengers to reach the aircraft is itself an important noise barrier. The construction of the DLR extension to the Airport and North Woolwich immediately to the south of the pier - see pictures on this page - will have added to this barrier effect but inevitably the trains will generate some noise of their own. The LBN has the right, after consultation with the Airport Consultative Committee, to request the provision of more noise barriers.

Top of Page

Ground Running of Engines

THE ground running of aeroplane engines for testing or maintenance purposes is only permitted during the opening hours of the Airport. On Bank Holidays, however, ground running for these purposes may not start until 09.00 hours.

The places where such running may take place, and the positioning of the aircraft and the noise protection measures to be adopted, are subject to the agreement of the local planning authority. The sitecurrently approved for this purpose is located at the north-east corner of the apron adjoining the King George V Dock. But the Airport can propose alternatives for  discussion with the local planning authority. The noise from ground running, as measured at homes adjoining the Airport, must not exceed 60dB LAeqT.

Aircraft Maintenance

WHERE work to maintain or repair aircraft gives rise to noise discernible at the Airport boundary it is permitted only during the opening hours of the Airport. On Bank Holidays, however, such work may not start until 09.00 hours.

Top of Page

Other Noise Abatement Measures

THE rules drawn up by the CAA for pilots using the Airport include the following noise abatement procedures:

  • Noise abatement procedures for aircraft departing from the Airport and joining controlled airspace are included in the Standard Instrument Departure (SID) instructions - see the ATC page.
  • Aircraft departing on other routes, or on training flights within the City CTR, must climb straight ahead to a minimum of 1000 ft before turning on track unless otherwise instructed by ATC.
  • Aircraft making approaches to the Airport without assistance from the ILS must follow a descent path which will not result in its being at any time lower than the approach path that would be followed by an aircraft using the ILS glide path.

European Directive 2002/30/EC - Rules and Procedures for Introducing Noise Related Operating Restrictions

This Directive, adopted on 26 March 2002, establishes principles for managing noise and rules and procedures for introducing related operating restrictions at Community airports. In the UK the Government gave effect to the Directive in the Aerodromes (Noise Restrictions) (Rules and Procedures) Regulations 2003 (SI 2003/1742) which came into force on 6th August 2003  The Directive does not require action to counter noise to be taken at any airport. Rather it sets out a process which must be followed where such action is being contemplated, a process designed to enable local solutions to be developed for local problems.

The Directive applies to civil airports in the EU with more than 50,000 movements a year by civil subsonic jet aircraft with a maximum take-off mass of 34,000 kg or more, or with more than 19 passenger seats. It has additional provisions for a small number of "City Airports", including London City Airport, being airports near the centre of a large conurbation and which are considered to operate in a particularly noise-sensitive location.

Where it is proposed to introduce noise-related operating restrictions the competant authority (at London City the Airport itself) will now be required to undertake a detailed assessment of the noise situation in the locality, and the full range of possible measures to address the noise problems identified. The process must be transparent and involve consultation. 

The Regulations give rise to interesting procedural issues where it is proposed to impose noise restrictions as a condition of planning permission, or by agreement under s.106 of the Town and Country Planning Act 1990, or (as at London City) significantly to alter existing restrictions imposed originally in that way.  How are the new procedures to be dovetailed with the planning procedures and decision making processes which involve the local planning authority in a leading role?

European Directive 2002/49/EC - Assessment and Management of Environmental Noise

This Directive, often known as the Environmental Noise Directive (END) came into effect in June 2002.

The aim of the END is to define a common approach across the European Union with the intention of avoiding, preventing or reducing on a prioritised basis the harmful effects, including annoyance, due to exposure to environmental noise. This involves:

  • informing the public about environmental noise and its effects;
  • the preparation of strategic noise maps for large urban areas (known as 'agglomerations' ), major roads, major railways and major airports as defined in the END; and
  • preparing action plans based on the results of the noise mapping exercise.

Such plans will aim to manage and reduce environmental noise where necessary, and preserve environmental noise quality where it is good.

The END should have been transposed into law by the Member States of the EU by 18 July 2004. However, because of the large number of complex technical details which had to be resolved, DEFRA found it impossible to comply with this deadline in the UK and it was not until September 2006 that the Environmental Noise (England) Regulations 2006 (SI 2006/2238) were laid before Parliament. They come into force on 1 October 2006. For more detailed information see:

London City Airport is both a “major airport” (more than 50,000 movements per annum) and located within Greater London. It was, therefore required to produce noise maps on a rolling basis.

The noise maps for London City and 17 other airports in England were publsihed by in December 2007 - these can be seen on the Department's website - click below for the maps relating to London City Airport:

Lden Contour - .pdf (3.05mb)
Lnight Contour - .pdf (3.05mb)

The maps will be used in “developing co-ordinated and cost-effective action plans to reduce noise”. This, too, will be the responsibility of London City Airport .

As yet there has been no response to the concerns expressed by the Consultative Committee's at the consultation stage as to whether Airport operators will have to pay for the noise mapping or how at London City Airport the action plans will fit in with the noise mitigation measures in force at the Airport by virtue of the Airport's planning permission and/or the 1998 s.106 planning agreement.

Sounder City - the Mayor of London’s Ambient Noise Strategy

In March 2004 the Mayor at last finalised and issued his Ambient Noise Strategy.  This 295 page can be seen/downloaded on the Mayor’s website . There is also a 16 page Highlights summary and an 8 page leaflet which are likewise available on the website.

The Consultative Committtee's report on the Strategy is attached. This notes that the aviation noise chapter of the Strategy is concerned mostly with Heathrow. So far as London City is concerned the Strategy notes that :

  • noise associated with London City Airport is managed under the terms of a planning agreement between the operator and the London Borough of Newham. The Mayor will keep relevant issues under review, having regard to developments in Thames Gateway and the Lee Valley.
  • the Airport is closed at night
  • at Heathrow aircraft continue to need to approach at a standard 3 degree glideslope. London City Airport, with specific obstacle clearance requirements, is exceptional in being limited to use by aircraft which can approach more steeply. Steeper approach reduces the area affected by noise.
  • there is a noise insulation scheme where homes are eligible for sound insulation at lower levels than any other airport in the UK.
  • the Mayor will work with the Government, Transport for London, the Airports and other stakeholders to improve public transport to and around Heathrow and London City Airports and to reduce the adverse environmental impacts otherwise associated with surface access.
  • the extension of the Docklands Light Railway (now opened), Airport Travel Plans and other measures need to continue to be vigorously pursued by airport employers to reduce the impact of private road vehicles in pursuit of overall environmental improvement.
  • aircraft manoeuvre over many parts of London. It may not always be clear to people in Tower Hamlets or Greenwich, for example, whether the aircraft they see are using Heathrow, London City or other airports.

Attitudes to Noise from Aircraft Sources in in England (ANASE)

This long running study was launched in May 2001.  Its aim was to research how people feel about aircraft noise and especially how they perceive the relationship between noise levels and annoyance, or sleep disturbance at night, and how they would value lower noise levels relative to other environmental factors. For more infomration about the progrewss of the study visit the UKACCs website

The results of the Study were finally published by the Department early in November 2007 - the consultants' report, together with peer reviews and Departmental statement papers, have been placed on the DfT website. See also the DfT's press release.

The Department say two key conclusions emerge from the study. First, that people are more annoyed by all levels of aircraft noise than they were in 1985, when the last major study in this field was carried out. Secondly, there is no identifiable threshold at which noise becomes a serious problem. Even relatively low levels of noise can cause some annoyance, which rises as the noise increases.

In December the Airport, in response to a question from Newham Council in connection with their interim planning application, prepared a note on the impact of ANASE at London City Airport (.pdf, 266kb).
