It varies, but normally it will be available through the regional governing body such as FAA in the US, Transport Canada/NavCanada in Canada, and so on. If it happens between publication dates on charts it may be in a NOTAM as well.

ok good to know, will check in the future. Maybe they need to be differentialted with different terminology according to status. So many things to contemplate between sim bugs, aircraft bugs and real world changes. It’’ be a shame when these systems bite the dust eventually. GPS just doesn’t have the same enjoyment/satisfaction factor for GA navigation.
I know the feeling, almost all the stations in the area I like to practice these old IFR skills have been decomissioned in the last 3 months, need to find a new place to to do that now.

Are they all still active in the sim? Just wondering what the update interval is for stuff like this in FS. Every sim update?
No, they’ve been going offline as the appropriate AIRAC updates are added to the sim.

oh right, and there was one of those last week as a small update after WU7 came out. I must try to keep an eye on this stuff. I had no idea. What I don’t get is surely there must be the need for a backup system to GPS other than visuals and compass or am I missing something?
This will either be because it’s a TACAN and not a VOR or because the sim incorrectly lists DME only stations as VOR’s. Both TACAN & VOR systems use the same DME specifications but different bearing signals so DME can be received by civil or military aircraft but the directional info is unique to each group.

Again interesting to know, thank you. I will try to pay more attention to which ones I encounter are like this and research them to find out. I’m not a pilot so this is all new to me.
Did a few more try and with variable success
with the islander bn2 I was able to catch up the nab frequency here
but in the next flight with the emb110 I wasn’t able to catch the one down here (I did tune it on both the active and standby position but the needle didn’t move even when extremely close)
can’t say if it’s a plane issues or I am doing something wrong (or even reading badly the skvector charts)
MS is terrible just terrible. Their own beacons as stated on their own maps don’t work. I noticed it on PA34T Seneca V and I wrote in to Corenado who advised “Our aircraft’s ADF uses the Asobo’s template and we try the Asobo’s C152 and it isn’t working either.” So I tested it on M$FS Cesspit 172 and confirmed the same. Some of the beacons on their maps simply do not work! I have submitted a bug report.
Examples:
Beacons SND, 362.5 (362 on MSFS map) 513434N 0004201E
CAM 332.5 (332 on MSFS Map) 521239N 0001059E
OX 367.5 (367 on MSFS Map)
What is really ridiculous is Just Flight’s Piper Arrows that clearly do not depend on M$FS work perfectly well picking up the same beacons.

I am a newbie so the forum won’t let me post a bug report which is very annoying. I have submitted the above via support. If anyone wants to post the above on the bug report navaids category by copying the above please be my guest.

The NDBs you mentioned all use spilt frequencies i.e xxx.5.
This system is primarily used in Europe. The Carenado Seneca emulates a Bendix King KR-87 ADF which only tunes in 1 KHz increments.
Indeed, the real KR-87 would be unable to tune any of the r/w NDBs you listed. If it could receive them at all, the signal would be weak and noisy.
The same holds true for the ADF in the default C152.
The Garmin G-1000NXi equipped aircraft in MSFS whose ADF can tune to the nearest 100Hz, receive these split frequency NDBs perfectly well.
This is not any kind of bug.

It is not tuning in to a real radio navaid. It is emulating one. Once again the frequency stated in the sim is 362 (EGMC example).
None of the ADF have half a frequency increment but cover the frequency so the half point is moot if you wanted to talk about the real thing.
And again the Just Flight Arrow which clearly does not depend on MSFS emulation of the beacon works perfectly (and it is not a glass cockpi).
The Cesspit 172 standard with X-Plane 11 has the same KR87 ‘like’ ADF with no issues.
This is totally wrong. IRL the 0.5khz makes very little difference because the ADF receiver bandwidth allows the signal to be received on the nearest whole frequency. The sim needs to model this same behaviour and allow reception if the nearest whole frequency is tuned. Currently it does not.
This has already been reported on these forums.

Thanks. That is correct. If the ADF simulation is correct then real ADF equipment has the bandwidth to tune in to 362.5 when freq is set to 362 or if signal is weak to 363. In any case the freq stated by the software itself is 362.
I have used these equipment in real flying and there is no 0.5khz button.
I did search the forum but I did not see the issue addressed properly. People start arguing about the sim’s ADF as though it is a real radio while in MSFS it is an emulation/simulation which is not working correctly.
—> Anyway this is a clearly bug. If it has been reported then it has not been addressed.
PS: since one poster earlier tried to confuse the issue by quoting technical details of KR87 below are the standards the real equipment need to comply. Note the European standard which real equipment complies without a 0.5khz button:
EUROCAE document ED-51 [Ref 4] specifies performance requirements, whilst in the US the RTCA document DO-179 [Ref 5] gives the minimum operational performance standards. The only difference between these documents is the requirement for 0.5kHz tuning resolution in Europe.
Thanks for your post, I needed that as I was thinking of doing a bit of VFR flying like the good ole days and landing on grass runways with a tailwind! 
Hi all, in Bell 407, am trying to receive morse idents on ADF. I have selected ADF audio on with green LED confirming on audio panel. ADF volume is up full. The indicator needle is working but no audio.
Any ideas please? Thanks, V
