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.
The consultation for the proposed approach procedures is now live and runs for 14 weeks concluding on 13th September 2017. Information on How to Respond to the consultation can be found below, including a link to the Consultation Document.
How will the consultation work?
The consultation is now live and runs for a period of 14 weeks. LSA has identified stakeholders that may have an interest in the proposal and they have been invited to respond to the consultation. The stakeholders identified, range from airspace users to local and parish councils. As well as the identified stakeholders, the consultation is open to anyone who wishes to respond and we invite your comments on the proposal.
How can you Respond to the consultation?
As the primary method, responses to the proposals should be sent to the following email address LSA.email@example.com. Responses should clearly indicate that they are a response to the consultation and if responding on behalf of an organisation this should be clarified.
Queries on the proposals may also be submitted to the above email address, clearly stating it is a query. If you are unable to submit your response by email, you may do so in writing to the following address.
PBN Approaches Consultation
London Southend Airport
Email responses will be acknowledged by an automated response, responses by post will not be acknowledged, so it is suggested a recorded delivery service is used. We cannot guarantee that a response submitted by any other means, than those above, will be accounted for in the consultation. Sections 2 and 7 of the consultation document, provide full details on how to participate in and respond to the consultation. If you require a printed copy of the consultation document please contact us as detailed above.
What happens next?
A Feedback Report will be published following the consultation which will summarise the key issues raised. This report will be made available through this webpage for download. 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.
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.
