This has nothing to do with older missions.

I have spoken with the dev, he needs to add some regression checking for changes that were made so older missions continue to work correctly, we should see improvement soon if things go to plan.

I never followed why DCS had the A-A TACAN functioning the way it did.  IRL I NEVER had bearing information using the TACAN in A-A mode between any A-A platforms (other fighters or tankers), just range against another platform on the same X or Y and separated by 63 channels from my own.  The TACAN plan generally allowed you to have a setup for a 4 ship (2xpairs) to range within each pair and between the two pairs by switching X to Y. For example, 29X, 92Y, 92X, 29Y for numbers 1,2,3,4 in a formation would give everyone the range between pairs (useful on a contra rotating CAP) but by switching your X to Y or vice versa you could range within your own pair quickly.

Well, thank you Frederf for your Long-long-long explanation,

But the fact remains that the bug was introduced with the Stable update DCS 2.7.9.18080.

Before that, I had performed countless missions in whose one had to engage AA TACAN mode in order to tune the Tanker.

But hey, now I have given a different frequency to the Supercarrier (1X) and the Tanker (2X) in my missions,

and as long as one does not engage AA-TACAN mode, everything works for both. 

So really not dramatic, but nevertheless something that has to be addressed by ED..........

[Frederf]

I know and it's as you say. I was responding to the comment about more research about behavior. ED obviously has interest in more than just putting it back the way it was (which had minor oddities despite functionality) but with as much confidence as possible making it accurate to not have to revisit.

To that end I had read into details before but not retained it. There were pulses and timings but the picture didn't come together until yesterday. And after going through the effort of understanding and summarizing for myself I should also share. Simply reading the primary docs did not seem clear on the first dozen passes.

There are flying TACAN stations with bearing. They are less common but they do exist in KC-135 form.

ATP-56(a) is a useful NATO joint document that covers Air to Air Refuelling. There is a Nov 2000 version readily accessible through a google search. A more modern version (2013) can be found by searching for ATP-3.3.4.2 as the NATO doctrine people changed the way pubs were numbered.  You could probably find an even later version if you look for it. The Annexes in Part 2 Chapter 10 (or Chapter 5 in the later version) spell out the capabilities of the different tankers. Some do have bearing capability (and a subset of those reference depending on receivers capability), but the vast majority do not. My experience was through the '90s and I never received a bearing from a tanker through A-A Tacan, even from those types listed on those annexes as having the capability. That may have changed since my time.

[ac5]

This is all very interesting, but what are you implying?....

 Engaging AA TACAN mode instead of solely T/R mode to find the the Tanker has always, since ages, being wrong in DCS?

 

[BlueSteel]

Hey Guys,

hope can help me.

Is there any function or knob i got to turn ON so that the Distance/Range to Tanker for A-A Refuelling will be shown in the EHSI in TACAN-Mode?

I already read any available manuals or watched every Step for Step Video on youtube but nothing helped so far..

THX already for your help!

[_SteelFalcon_]

it's a reported bug, you probably did it right but it just doesnt work atm

Thanks for the Answer!

Good to hear that this is a known problem so far.

[84-Simba]

I think you can use the regular TR-mode instead of AA-TR for now, I think it works.

I prefer to use the HSD and the FCR in RWS.

[ac5]

Just sayin.... 

This was not corrected in todays update to DCS 2.7.10.19473 Stable version.

[Inanity]

Any updates on this? I understand if it's not high priority but I wanted to bump that the issue persist on version: DCS 2.7.12.23362 Open Beta (digitalcombatsimulator.com).

[ac5]

And so it does on the last stable version.....

[skywalker22]

Indeed would be awesome to read if there has been any progress done on TACAN. Lets give them some time.

[lax22]

This should really be patched via hotfix.

A/A Tacan is a crucial part of this game and needs to be fixed asap.

[ac5]

Indeed... And even more so, because the bug was introduced with the Stable update DCS 2.7.9.18080.

Before that, I had performed countless missions in whose one had to engage AA TACAN mode in order to tune the Tanker 

or other airborne units.....

[VMFA117_Poko]

Still no news about the fix?

[ac5]

After at least a dozen updates, and well over two years, still not fixed.......

[ac5]

I appreciate all the "likes", but some statement from ED regarding this would also be welcome.......

[skywalker22]

@BIGNEWY do you maybe have any news about Tacan?

This was fixed some time ago, if it is broken again please post a new track replay example and we will take a look. 

Please bear in mind with tankers you have to use T/R not AA

I do have a F-16 TACAN issue reported, but if it is more than that please attach new track replay examples. 

thank you

And the dev team says it's correct as is?

Yes it is correct, they should only give DME. 

There are some cases of A/A being used by tankers in real life ( like the KC-10 ) but not the ones we have in DCS apparently they should use T/R.  

 

[skywalker22]

 

[ac5]

Before January 2022 all air assets in DCS used A/A tacans, and all ships and ground T/R.......

Why do all Air and Ground assets now use T/R ONLY? 

This is certainly not correct.. Otherwise why is an A/A setting / selector in

the F-18, F-16 A-10???
