Flight Paths across South Norwood (SE25)

The request was successful.

Dear Civil Aviation Authority,

Please could you provide me a map of flight paths across south London?

Also could you provide me with the flights paths specifically for the SE25 postcode?

I've also noticed increased number of flights within the vicinity of SE25, have any of the flight paths changed.

Yours faithfully,

Darren Smith

The substantive text of the reply stated:

Having considered your request in line with the provisions of the Environmental Information Regulations 2004, we are able to provide the information below.
Perhaps it would be beneficial in the first instance to provide some background information to explain the way in which the airspace above the UK is structured and the procedures flown by aircraft operating within it.
Airspace is divided into 3-dimensional blocks which are classified from class A to class G
airspace. In the UK class G airspace is uncontrolled, which means there are no restrictions on which aircraft can enter it, what equipment the aircraft must carry and/or the routes taken by the aircraft. All other airspace classifications represent controlled airspace, within which aircraft are directed by air traffic controllers; they decide the safest and most efficient routing for every aircraft (taking into account the surrounding conditions including the weather and other aviation traffic). The most efficient routing for any aircraft is one that enables it to reach its destination most directly using the least amount of fuel. These decisions are sometime referred to as tactical vectoring of aircraft.
Controlled airspace can be split again into other blocks. For example around groups of airports there are terminal manoeuvring areas and for individual airports radar manoeuvring areas. These are decided on and run by air traffic control organisations through their operational procedures. Within this airspace air traffic controllers tactically vector aircraft to get them into and out of airports in the most efficient way.
An international network of routes links these sectors of airspace. Near to airports these are called Standard Instrument Departure Routes (SIDs) and Standard Arrival Routes or (STARs); these procedures will provide aircraft with a link to the Lower and Upper Air Traffic Service (ATS) routes (also known as ‘airways’).
Turning now to your specific request, the airspace above the SE25 area is, from surface level up to 2,500 feet above mean seal level, class G airspace. Controlled airspace, namely the London Terminal Control Area (LTMA), is established from 2,500 feet amsl upwards; the LTMA is established for the separation and sequencing of civil air transport movements utilising airports in the South East. The most notable traffic over the SE25 area will be that which is operating in to/out of London Heathrow airport.
You may already be aware that for aerodynamic reasons aircraft normally take-off and land into wind. As the prevailing wind in the UK has a westerly component on approximately 70% of occasions, aircraft will approach the airport from the east and depart to the west for the majority of the time (so-called ‘westerly operations’). When the wind takes on an easterly component the flow is reversed (so-called ‘easterly operations’).

The SE25 area will be affected by London Heathrow arrivals when the airport is operating on ‘westerlies’ and departures when it is on ‘easterlies’. I have enclosed annual flight maps (from 2013 and 2015) which have been taken from the airport’s noise website (www.heathrowairport.com/noise) that display a typical days worth of westerly arrivals and easterly departures. The approximate location of the SE25 postcode area has been marked by a red circle on each map. The tracks/heights of the aircraft on each of the maps are very consistent, which suggests that there has not been a significant change in terms of the tracks flown by aircraft operating in to and out of London Heathrow airport. Should you wish to make further enquiries concerning the aircraft operations associated with London Heathrow airport, I would encourage you to contact the airport’s Community Relations Team directly by using the following contact details:

Community Relations Team Second Floor South
The Compass Centre Nelson Road
London Heathrow Airport Hounslow
TW6 2GW
Tel: 0800 344 844
Email: noise@heathrow.com

It is possible that the SE25 area may also be affected by aircraft positioning for their final approach in to London City airport when it is operating on easterlies. Whilst the airport does not publish flight maps on their website, they may be able to produce a similar graphic for you upon request; the airport’s Environment Team Office can be contacted by telephone on 020 7646 0200 or by submitting an environmental enquiry via their online form.
There are also a number of ATS routes that pass directly over the SE25 area and these are listed below:
Lower ATS routes: L9, Q70, L980, L15, T420, N16.
Upper ATS routes: UL9, UQ70, UL980, UL15, UT420, UN16.
Information related to these routes is published in the En Route section of the UK Aeronautical Information Publication, the full content of which can be accessed through the NATS Aeronautical Information Service website (www.ais.org.uk). For ease of reference we have included the relevant extracts from ‘ENR 6 – En Route Charts’ and have marked the approximate location of the SE25 area with a red circle. With regards to the level of aircraft traffic utilising the ATS Routes it should be noted that the CAA is not directly involved in the provision of air traffic control services nor is it responsible for monitoring individual aircraft movements; consequently, we do not hold any records that would enable us to confirm whether or not there has been an increase in the utilisation of the ATS routes over the SE25 during recent years.

If you are not satisfied with how we have dealt with your request in the first instance you should approach the CAA in writing at:-

You may want to keep an eye on the Heathrow Community Noise Forum site which has a work programme to carry out various "gate analyses" to establish flight paths over particular areas and changes over time.

http://www.heathrow.com/file_source/Heat...

shows a recent map of proposed locations

and completed reports are listed at

http://www.heathrow.com/noise/heathrow-c...

The Teddington and Twickenham reports may be of interest as the departures from there will be heading towards South London. They do show the effects of increased usage, concentration and the lowest aircraft are flying lower....
