The LYDD VOR (LYD) in SE England is now listed in your data as DME only, however I have had confirmation from a real pilot today that it is still a VORDME.
Hi,
sorry to say but your reference is wrong. I have checked NATS UK (AIP) and here the LYD navaid is also official published as DME only.
I don’t find any official/published information nor notam, where this navaid is designed as VORDME. Our data reflects the real world and as you see in the AIP UK, it is published as DME only.
Hope that helps
Richard
Well, my “reference” is literally a pilot who used it today, but whatever.
Dear Navigraph
I too have noticed something very odd on your excellent app - Lydd VOR (LYD) in Kent, UK is showing as only DME.
In the real world (on a flight today) I can confirm that it is definitely a working VOR and DME, not just the latter.
I used it today.
It has always been a VOR/DME and features in various SID’s from airfields around London (e.g.Biggin LYDD2 departure)
A fault in your database and also (it seems) on the NATS site - strange.
Regards,
David
Hi again,
possible it’s a VORDME but the main source (the NATS UK) shows it as DME and thats the base for the data provider.
The data provider must trust the official source, coming from the countries.
Sorry, but in this case, when this navaid has really the wrong type, it’s an issue in the AIP and not an issue from the data provider, nor from us.
Not sure how, but possible you can report this to NATS UK, that (at least) can check this.
Cheers
Richard
The AIP most likely reflects the intended decommisioning of the LYDD VOR this year as published by NATS:
The LYD DVOR in the south of England was selected to be removed from our network of ground based NavAids and the Airspace Change Proposal (ACP) which dealt with the associated network changes was approved in October 2018. The LYD DVOR is scheduled to be decommissioned by the end of 2023.

It should be noted that the specific field your are looking at is not the reference used by your provider, as most of the “DME-only” (when using said field as reference) entries on that page are actually still listed as VOR/DME in Navigraph data:

DUF, GLO, LYD, NEW and WIN are the only ones from that page which are actually DME-only in Navigraph data. No idea where the difference comes from.
Might be interesting to get to the bottom of this somehow.

The data provider get normally the information from the countries in a special file format and doesn’t compare every chapter from the AIP.
Means, such information is only one part of it but not the only one. It’s a combination of several sources, as you also see this here with the notam.
We (as user/customer) can only compare the AIP (+ notams) and thats also at least one parameter of the data provider source.
Cheers
Richard
