London Airspace Management Programme

From 4 September to 27 November 2014 London City Airport (LCY) consulted on proposals to modernise its flight paths, to allow the introduction of Area Navigation (RNAV), superseding the ground-based navigational systems used today. The consultation is a statutory requirement according to Civil Aviation Authority (CAA) regulations.

The London City Airport proposal sought to replicate the existing conventional flight paths with equivalent RNAV routes. The concept is not optional - a legal mandate is being introduced by the Civil Aviation Authority which will require all aircraft to be equipped to navigate using RNAV by November 2017, and a mandate for the airspace to provide RNAV routes is expected to be effective by winter 2019.

The proposed changes are key to achieving network efficiency and reducing delays in the south and are an important part of the London Airspace Management Programme (LAMP), NATS’ wider programme to modernise the air route system over London and the south east.

London City Airport has produced a Consultation Feedback Report based on the responses received during the consultation period. The Consultation Feedback Report can be found with the LAMP Consultation Document and the LAMP Consultation Document Appendices on this page.

What is this consultation about?

This consultation concerns enhancements proposed to the navigation systems (introduction of Area Navigation or RNAV) which define the standard arrival and departure routes to London City Airport.

This proposal seeks to replicate the existing conventional routes with equivalent RNAV routes. The new RNAV routes have been designed to replicate the conventional routes as closely as possible (within the rules of what is allowed for RNAV routes).

The purpose of this consultation exercise is to allow stakeholders to consider the proposal and provide London City Airport with feedback.

We are asking that the impact of the proposed change from conventional navigation to RNAV route is considered, along with the impact, if any, it could have.

What is RNAV?

RNAV is an advanced, highly accurate method of aircraft navigation.  RNAV (Area Navigation) is the ability of an aircraft’s Flight Management System (FMS) to navigate by means of waypoints defined by latitude and longitude, rather than by conventional ground based navigational aids. Basic Area Navigation (B-RNAV ) has navigational accuracy ± 5 nautical miles either side of a routes centreline and its capability is mandated in UK controlled airspace currently.

The RNAV (technically known as RNAV1) has an accuracy of + 1 nautical mile either side of the centreline which allows better track keeping and as such the replicated route’s proposed for London City Airport are all designed to this specification.

What do these proposals mean to people living, and businesses located, near to the airport?

Aircraft departing from, and arriving at, London City Airport will continue to fly along the same routes as they do today. However, because these will become RNAV routes, the aircraft will fly them more accurately, meaning they will be consistently closer to the centreline of said route.

This has the effect of reducing the overall area overflown, but it will increase the concentration of over-flights in some areas beneath the centreline of the given route.

Is London City Airport alone in this concept?

London City Airport is not alone in changing over to RNAV routes. The proposed changes are an important part of the London Airspace Management Programme (LAMP), a  wider programme to modernise the air route system over London and the south east that is being led by NATS, the UK’s leading provider of air traffic services. This is essential for the delivery of the Future Airspace Strategy (FAS), the Civil Aviation Authority’s blueprint for modernising airspace by 2020.The undertaking of LAMP and the introduction of RNAV routes at airports is not optional - a legal mandate is being introduced by the Civil Aviation Authority, which will require all aircraft to be equipped to navigate using RNAV by November 2017, and a mandate for the airspace to provide RNAV routes is expected to be effective by winter 2019.

Why is the consultation required?

While the London City Airport proposal is for replication of existing flight paths to make them RNAV compliant, the CAA's Airspace Change Process and the CAA Policy on RNAV replication of conventional procedures state that formal consultation is required to ensure that the London City Airport Consultative Committee has the opportunity to provide feedback.

Right arrow

What is this consultation not about?

This consultation only concerns aircraft arriving to/departing from London City Airport. It is not related to air traffic growth in general nor changes to the ground-based infrastructure at London City Airport.

This consultation is specifically not about the permission that London City Airport has to increase its flight movements to 120,000 per annum, nor is it about the City Airport Development Programme planning application which is with Newham Council for determination.

This consultation is also not concerned with RNAV as a future tool, any other or future development, any aspect of Government airport or airspace policy or the establishment of controlled airspace.

Right arrow

Who are the stakeholders in the consultation?

This is a public consultation, however the key stakeholders are:

  • The London City Airport Consultative Committee (ACC) which includes representatives of Local Authorities, community representatives and other organisations that have expressed an interest in the activities of the airport
  • Members of the National Air Traffic Management Committee (NATMAC) which includes representatives of all types of airspace users.
  • Airlines that operate from London City Airport.
Right arrow

How long will the consultation period last?

The consultation will begin on 4 September 2014 and end on 27 November 2014, a period of 12 weeks.

Right arrow

What happens to the responses to the consultation?

Responses to the Consultation are used to prepare a formal submission to the CAA Safety and Airspace Regulation Group (SARG) regarding proposed routes.

Right arrow

When does the CAA SARG decide on the outcome of the consultation?

Following consultation, London City Airport will submit an Airspace Change Proposal (ACP) to the CAA. The CAA will make a decision within 16 weeks of the submission of the ACP. This is expected to be during the summer 2015

Where can I go if I have concerns regarding how the consultation is being carried out?

This consultation is being conducted by London City Airport. The CAA SARG will oversee the consultation, to ensure that it adheres to CAA process and government guidelines. If there are any complaints about how this consultation has been conducted, these should be referred to:

Airspace Business Coordinator
Airspace, ATM and Aerodromes
Safety & Airspace Regulation Group
CAA House
45 - 59 Kingsway


Please note that this address is for concerns and complaints regarding non-adherence to the defined consultation process. The SARG will not engage with consultees on details of this consultation. Response to the nature of this specific consultation should be addressed to London City Airport. The SARG will receive details of your response as part of the formal ACP submission for this proposal.
