Proposed arrival routes

RNAV Approach Procedures

Following on from the implementation of Controlled Airspace in April 2015 and the project to implement Standard Instrument Departures, which is still underway, London Southend Airport (LSA) has started the process to introduce RNAV Approach Procedures.

Latest News

The RNAV Approach project kicked off in 2016 and since then LSA has been developing procedure designs and working on a consultation which will be launched in early May 2017.

How will the consultation work?

The consultation is planned to begin in May and run for a minimum period of 12 weeks. LSA has identified stakeholders that may have an interest in the proposal and they will be invited to respond to the consultation. The stakeholders identified, range from airspace users to parish councils. The consultation document will be available for download from this web page. The consultation is open to anyone who wishes to respond and we invite your comments on the proposal. More information will be available about how to respond to the consultation on this page once the consultation is launched.

Why is LSA doing this now?

With modern technology, many commercial aircraft flying in the UK have the potential to use what is termed Performance Based Navigation (PBN); navigation which does not require a ground based infrastructure. This technology gives aircraft the ability to follow a route with a greater level of accuracy than they do today. LSA wants to ensure that it offers the most up to date procedures for its customers. PBN procedures are recommended by the UK Civil Aviation Authority (CAA) as part of its Future Airspace Strategy (FAS). For more information on FAS please click here.

What are RNAV & RNP Approaches?

There are several versions of PBN. LSA is interested in both RNAV (Area Navigation) precise navigation without on board conformance monitoring and RNP (Required Navigation Performance) where aircraft must have on board monitoring equipment to alert the crew of any deviation from the desired track.

Area navigation (RNAV) is a method of instrument flight rules (IFR) navigation that allows an aircraft to choose any course within a network of navigation beacons, rather than having to navigate directly to and from the beacons. It is known as Performance Based Navigation (PBN) and it can reduce flight distance, reduce congestion, and allow flights into airports without conventional (ground based) aids.

RNAV approaches have been made possible by the widespread availability of high performance RNAV systems on all types of aircraft and in particular by the use of GNSS (a form of aircraft satellite navigation, not unlike that used in a car).

Do these proposed procedures replace any existing procedures?

No, these procedures will be in addition to the other flight procedures LSA offers. They provide an alternative option for aircraft operating into LSA and also provide a back up should the Instrument Landing System not be available. Where possible, LSA has attempted to replicate the existing approach tracks.

What happens to the existing S106 Noise Abatement Procedures?

The Noise Abatement Procedures currently in place at London Southend Airport for departing aircraft do not change as a consequence of this proposal and will continued to be applied and reported on, in the same way.

I have a view on this - how can I make my opinion heard?

The government body which regulates changes to UK airspace and the route network is the UK CAA. The CAA requires each airport seeking to introduce new routes to put forward a case which justifies their application, and shows that all interested parties have had an opportunity to make their views known. The CAA then decides on the merits of the proposed change and whether or not to grant the application to implement the change. Once the consultation is launched, this web page will contain a link, through which you will be able to download the consultation document and information about how you will be able to submit your comments regarding the proposed changes. Further details and instructions will be provided in the consultation document.
