What is Heathrow West proposing?

We are proposing a consolidated terminal campus located to the west of Terminal 5, to serve the new Northwest Runway at Heathrow Airport, which is an alternative to the proposals being consulted on by Heathrow Airport Limited. Our proposals will give Heathrow Airport opportunities to more successfully achieve the ambitious targets to increase travel to Heathrow Airport by public transport enshrined in Government policy and provide better links with the Colne Valley Regional Park and local communities.

Why Heathrow West?

We believe there is a choice and a better way to deliver the increased capacity at Heathrow Airport identified in the ANPS. We have a fresh perspective and believe there is a delivery route that will secure long term value, competition, and local and national benefits, whilst not compromising on quality or safety. We are therefore promoting a DCO for a single western terminal hub at Heathrow that we intend to develop and operate within the wider airport expansion plan.

The model is not new and there are many successful precedents around the world that provide excellent benchmarks, including Schiphol in Amsterdam. We believe that the policy requirements of the ANPS are best achieved through the new terminal capacity to be designed, delivered and operated by Arora; with Heathrow Airport Limited designing, developing and operating all remaining airside operations.

Are these proposals for a third runway?

No, Heathrow West’s plans do not include the third runway, or the major works associated with the M25 and as such these were not part of our Stage One consultation. Heathrow West’s proposal would fit with these elements of Heathrow Airport Limited’s proposals.

What do your proposals include?

At a high level, the Heathrow West proposal comprises:

  • New and reconfigured terminal capacity to the west of Terminal 5 that will provide increased passenger capacity of between 45 and 50 million passengers per year and support the additional 260,000 air transport movements to be provided from the third runway;
  • Expansion of the existing airfield, including taxiways to the new runway and stands for the new terminal;
  • Changes to the existing roads, including junctions 14 and 14A of the M25;
  • Upgrades to achieve the significant increase in the use of public transport required by the Government;
  • Facilitating the proposed changes to the existing rail infrastructure;
  • Changes to river alignments and enhancements to flood alleviation;
  • Landscape, recreational and ecological improvements;
  • Car parking;
  • On-site energy generation and ancillary facilities.

How will the terminal be designed?

We are proposing a centralised approach, comprising a main terminal building with boarding gates located in either piers or satellite buildings. A centralised terminal building is a more efficient design as facilities can be located together and therefore less land is required to accommodate the same number of passengers. It also provides a better experience for passengers, as all will benefit from access to the whole range of services on offer. Passengers are also able to enjoy the facilities for longer as they can be called to the boarding gate later.

Decentralised terminals, by contrast, have some facilities located in satellite buildings, with amenities located between the main terminal and satellite as well as in each location. This results in some duplication and a greater amount of land required.

Where will the boarding gates be located?

Terminals locate boarding gates in either ‘satellites’ or ‘piers’. The main difference in design is that piers are attached to the main terminal building and satellites are not. Satellites allow for greater capacity and flexibility of the aircraft stands and are generally more efficient. Heathrow West is proposing linear north/south satellites, making the most efficient use of the apron. We are consulting on four different options for how this could be configured, some which would retain the existing Terminal 5 multi-storey car park and some which would see it replaced.

Where would the aeroplanes be parked?

Aircraft are parked in areas known as ‘aprons’, located adjacent to terminals and used for passengers to get on and off planes, for loading and unloading cargo, and for servicing. Heathrow West is considering three different types of apron:

  • Active contact stands, where the aircraft is connected via a passenger board bridge to the terminal and passengers enter and exit the aircraft directly;
  • Active remote stands, where the aircraft is located away from the terminal bridge and passengers are taken by bus to enter and exit the aircraft; and
  • Inactive stands, where aircraft are parked overnight or temporarily grounds for maintenance.

How will aircraft access the new runway?

Taxiways are the defined paths that allow the safe movement of aircraft from aprons to the runway.

  • Parallel taxiways: these run parallel to the runway, with two taxiways serving each runway. They connect to the runway by the exit and access taxiways and connect to the apron via the crossways (see below). The existing parallel taxiways will be extended and aligned;
  • Cross taxiways: these provide a link between aprons and parallel taxiways. Heathrow West is proposing two locations for cross taxiways, one west of the new terminal and one west of the existing runway and parallel to the M25.

Heathrow West will also provide taxiways to serve aircraft accessing the aprons and their parking position, to reduce congestion and delays around the passenger terminals.

What are the landscape impacts?

Our proposals will extend the airport into the Colne Valley and into areas which are currently Green Belt. These areas are already currently affected by the airport. We will minimise the land take and ensure our proposals for Green Infrastructure will mitigate and provide enhancement to landscape, biodiversity, recreation and water environments. We will be consulting widely with interested parties in developing our proposals.
