ILS of Andersen AFB RWY 24L not working

[Furry D]

ILS of Andersen AFB RWY 24L FREQ 110.1 not working. GS indicator stays frozen. LOC indicator reversed. It’s only functioning from the opposite side (06R).

BTW I tested all these by F-16.

Did you set the proper wind to force RWY 24 to be active?

Should still only work one way on that field, shouldn't it?

What exactly do you mean?

What OP is describing is that RWY 06 is active and he is getting the localiser backcourse of it (condition being of course that the ILS has the same frequency for both directions). And just to rule out all factors and DCS's irregularities, forcing the wind to make sure that 24 is indeed the active one would help to confirm wheter or not it is working correctly or not.

I just looked at the chart and assumed the localiser was one direction only, like in some airfields in the Caucasus.

Yes and no. A Loc approach is supposed to be flown from one and only one direction. However, a localiser antenna is also radiating backwards so you could capture the backcourse of it. Just that this isn't done anymore and there is no need for a backcourse approach if you have an ILS for it instead. The airfields on Caucasus you mean don't have an approach from the opposite because of mostly terrain reasons, sometimes money reasons. But if you were to place your aircraft on the opposite of the ILS you tuned to, you should still get the localiser backcourse of it. https://www.boldmethod.com/learn-to-fly/systems/how-to-fly-a-localizer-back-course-approach/

And as far as I know backcourse was always a thing in DCS. But I am not sure in this case as I don't know the frequencies by heart but judging by the description, it does seem to be the case as it perfectly matches what you expect from a Loc BC approach, no glideslope and reversed Loc sensing.

For some reason they've made the frequencies .05 MHz apart in DCS:

Perhaps a DCS limitation?

Either way, OP not only flew from the wrong direction but also used the wrong ILS Frequency.

A good example I guess that shows not everything in DCS is realistic and that there may be a difference between real world and ingame content/charts/frequencies.

Hi. 24L was the desired RWY I was heading. And I also flew the correct heading 244. The ILS Frequency was wrong.

I just leart from Minsky that the ILS Freq was different from the real world. I haven't found this infomation in game as it's not shown at the info chart in F10.

We can't fly without these real world data. Just like we can only learn the ILS profile from a real chart. We can't get rid of it. So it will be quite bothering if ED randomly change some data from the real data without marking it.

So just to clarify when you contacted the ATC it told you RWY 24 is active and not 06?

Open mission editor, and the map lists four different frequencies. One for each runway and direction.  

Very strange none are listed on the in game map.

Bug ?

Bug or negligence. Who knows?
