No TACAN to tanker


Recommended Posts

If I use Jester to locate the tanker via TACAN, I can see bearing and range for some seconds, but both vanish after some time. It was working before - is that a bug or is there a workaround?

Currently in DCS Open Beta you have to use T/R for tankers. A/A only works for fighter to fighter.

Not sure if this is a bug or feature.

Edit: OH wait you're using Jester to do it? Hmm I dunno then. Maybe he didn't get the memo to use T/R mode. I haven't tested it via Jester yet.

I think something similar is happening with the carrier as well in Instant Action recovery missions. TACAN works as I approach the carrier, and then after the break bearing and range information disappear. It was working well before. I am using the stable version

There's two ways you can set up a Tacan for a unit (ship or tanker). Either via waypoint actions or via triggered actions. The latter seems to be bugged sometimes so try using a waypoint action at waypoint 0.

Is this only for the Tomcat? A/A works in the Hornet for tankers, or at least partially. T/R is sour for me.

Really? Very weird. I just made a miz to test it. I made a client slot for a F-14B and an F-18. I made three tankers, an S-3 (3Y), a 130 (2Y), and a 135MPRS (1Y). In the F-18 I don't get TACAN information on any of them if I have the : next to A/A. I only get sweet TACAN if I remove the :.

In the Tomcat I'm getting a sweet TACAN on both A/A and T/R, so that's inconsistent with what my understanding of the current TACAN modelling is. (My fault for replying to things before properly testing myself). All I know is some of the guys in my wing have reported broken tanker TACANs in some of our F-14 training miz files, and they were able to fix it by switching to T/R. But yeah...both of the modes seem to work on my end.

I don’t know if it’s properly implemented in DCS, but try the following:

Set the Tanker Tacan to 92y. Set 29y A/A Tacan in your own jet and see if it works. That’s how it’s often done in real life. 
Btw, it doesn’t have to be the 92/29 combination. Any two numbers that are 63 apart works. 92/29 is just easy to remember.

It doesn't work that way in the mission editor. When creating a tanker you assign it a TACAN value that the clients are supposed to use. Just like the various ground TACAN stations around the map.

I've been using channels like 63Y. Tune to 63Y, A/A, I get DME but no bearing. My understanding is the DME part is realistic, but like Matze said I should be required to set my TACAN 63 away. Currently that part doesn't work. Occasionally I get channels that don't work at all, like 28Y. No permutation of T/R, A/A, X/Y, or even 63 away will work.

Oh wait, I'm dumb. I forgot to respect this TACAN chart when i was testing the Hornet.

That's probably why I wasn't getting anything with A/A set. Interesting how regulsr T/R gave me perfect range and bearing to 1, 2, and 3 Y.

I've not seen that chart before? Is that tracking the bug or is that realistic. Are we not supposed to use those channels?

That chart doesn't seem to be completely implemented in DCS. I often use 29Y for tankers and it works fine in the Hornet and Tomcat despite supposedly being unavailable.

With Link16/MIDS DL active at the same time?

DCS Panavia Tornado (IDS) really needs to be a thing!

No, I believe it's a feature/realistic. But I think it's F-18 only.

In the Hornet I assume so, since TACAN ON automatically activates those as well. Those channels also worked on the Viper and Hog in the past, but I haven't flown either of those in roughly a year.

I did a little bit more testing with the Tomcat TACAN this morning. On one of my older missions I see some weird behavior. There's a CVN-72 (72X) and a nearby S-3 (1Y).There's also a few other things in the miz, but nothing with competing TACANs. On entry into the cockpit via parking/hot it auto selects the TACAN to 1Y A/A, but I get a sour signal. I only get a sweet TACAN on 1X T/R mode which doesn't make a lot of sense.

I created a brand new miz with only the CVN-72 and S-3, both same TACAN settings as the old miz. On the new miz the 1Y A/A settings works perfectly and gives me bearing and range to the S-3, as does the 72X T/R for the boat.

Very weird. The only difference between the two miz files aside from less stuff, is on the older miz I set the CVN TACAN via trigger rules and on the new miz I set the TACAN via the regular advanced waypoint actions method. So I wonder if there is a conflict with that, or maybe missions created on a much older version of the OB have TACAN problems. It's a mystery. 🤷‍♂️

I've got the same problem. Appeared in the last couple of weeks. 

TACAN is on and works perfectly in T/R mode to carrier, but I can't find any tankers.

To navigate to tanker my procedure is as follows:
1: Set TACAN to A/A
2: Set TACAN chn. as on kneeboard

I'm playing with VR, so the screenshot is not optimal, but hopefully you can see my kneeboard, Arco (S-3B) in front of me, and the TACAN setting. And the fact that the TACAN can't find anything.
Can anyone see anything I might be doing wrong? If not this is definitely a bug.
