Verdict on 3rd runway legal challenge: 28th February


It has been announced that the High Court will deliver its verdict on the legal challenge brought by some local authorities and environment organisations, as well as the Mayor of London, on 28th February.  This is an appeal against an earlier court ruling which found decisively against the applicants.

Further Consultation on 3rd runway

7th January 2020

Heathrow has confirmed today it will put in a 3rd planning application this year but it will be preceded by an additional 8 week consultation (15th April- 11th June) as the work on the runway will take longer than expected because the Civil Aviation Authority has refused Heathrow to spend more money on a new runway not in advance of getting permission for it.  If it is given permission, it may now not open until 2028/29.

3rd Runway: not a done deal

Boris Johnson was careful to keep his options open during the recent General Election campaign.  The Conservative Party manifesto said this: “Parliament has voted in principle to support a third runway at Heathrow, but it is a private sector project. It is for Heathrow to demonstrate that it can meet its air quality and noise obligations, that the project can be financed and built and that the business case is realistic. The scheme will receive no new public money.”

Next steps on flight paths and runways

A lot of questions about what happens now to flight paths and runways following the major consultations this year.  We have drawn up a Layperson’s Guide: guide

HACAN is lobbying for short-term action to improve noise and flight paths.  Read our report:

Have flight paths changed?

We get more emails and queries about this than anything else. The answer is that since 1996 there have been no formal changes.  But two things have happened.  Over the last decade or so departures have become increasingly concentrated down the centre-line of the Noise Preferential Routes (the three mile wide area they must stay in when leaving the airport) and the corridors used for arrivals have become more concentrated.  It means some areas are getting many more planes and others less.

Additionally, air traffic controllers are permitted to vary the number of planes over individual areas as they guide aircraft in and out of the airport. An increase in flights can also occur if there are more flights arriving from or departing yo particular destinations.

HACAN: giving a voice to residents

We are a regional body with thousands of members from Reading in the west to Greenwich in the east.  We aim to give a voice to residents under the flight paths.

Our objective: to campaign for a significant reduction in noise for all communities impacted by Heathrow

Our key campaigns 2019 – 2020

  • oppose a third runway
  • retain existing alternation in West London
  • meaningful respite – day and night – for all communities
  • a noise envelope that works for all residents
  • Heathrow and London City to coordinate their new flight paths
  • less concentration of current arrivals and departures
  • steeper landing and take-off procedures
  • oppose Independent Parallel Approaches

HACAN  sits on a number of bodies:

  • ANEG – the Government’s national noise stakeholder board
  • Airspace Design Ministerial Group – chaired by the Aviation Minister, overseeing national plans for airspace changes
  • European Commission’s Noise Expert Group
  • Heathrow Community Engagement Board
  • Heathrow’s Strategic Noise Forum
  • Heathrow’s Community Noise Forum
  • Heathrow’s Noise Envelope Design Group

Our sister organisation, HACAN East, gives a voice to residents under London City flight paths.  Of course, a lot of people are under the flight paths to both Heathrow and London City. For more details on the vibrant campaign against the expansion plans of London City visit:

Here is a great video HACAN East has produced and released today showing not only what it is like to live with London City – and Heathrow – planes flying overhead but also what possible solutions might look like:

A Flight Path Revolution

18 June 2019

Heathrow  is planning the biggest change to its flights paths since it opened in 1946.  It will have a fundamental impact on residents.

Below is the latest information on flight paths:

We will not know the proposed new flight paths until 2022

Heathrow’s major consultation on its flight path options closed on 4th March.

For more details on the proposals:  Heathrow Flight Path Consultation: January to March 2019: Details on consultation and responses  

The consultation its 3rd runway proposals, also now closed,  included further proposals on night flights, runway alternation and westerly preference as well as Heathrow’s proposed noise envelope.

For details read the noise section of the HACAN Briefing

Heathrow still in a noisy league of its own

The numbers are taken from the latest noise action plans published by the UK airports in early 2019.

Many people are in despair about the constant noise over their heads.  95% of the emails HACAN gets contain a complaint are from areas which get no respite from the noise.  Read more here

Read why HACAN backs respite here

We also get a lot of questions about the metrics used to measure noise annoyance. A short HACAN paper explaining noise metrics.

The impact of a Third Runway

A new runway at Heathrow would mean just over 700 extra flights each day.  A total of 760,000 planes would use the airport.  Currently there is an annual cap on  flight numbers of 480,000.  A third runway would mean people in West London under the existing flight paths will lose part of the half day’s break from the noise they currently enjoy. It would of course also mean many people under an arrivals or departure runway for the first time. On March 21st 2017 a new coalition was launched to oppose a third runway at Heathrow.  The No 3rd Runway Coalition consists of 18 organisations and is backed by MPs, peers and local authorities.
