STKDirty Posted December 24, 2021 Share Posted December 24, 2021 I noticed after the latest OB patch that the DME distance for aerial TACAN, aka tankers, is no longer there. Was that intended? Is anyone else seeing that? I'll provide more detail if that is not the intended behavior of TACAN for aerial targets. Thanks! Link to comment Share on other sites More sharing options...

AG-51_Razor Posted December 24, 2021 Share Posted December 24, 2021 I just noticed the same problem. 71X set up for air to air gave me a bearing as well as the correct identifier, ARC, but no distance or time to station. Others in my squad reported the same thing. It was correctly put in the ME for that tanker also. [sIGPIC][/sIGPIC] Link to comment Share on other sites More sharing options...
Dunx Posted December 24, 2021 Share Posted December 24, 2021 Confirmed, TACAN is broken. 1. Created mission with 2 tankers and carrier... all TACAN appear without using AA option (73X, 30X, 31X) 2. Edited mission, changed tanker from 31X to 30Y... all TACAN stations lose distance and codes (73X, 30X, 30Y) Please move this post to Bugs. test-tacan-1.trk test-tacan-2.trk ROG Z690 Hero ● i9-12900K 5.5GHz ● Giggy RTX 3090 OC ● 32GB 4800MHz ● Firecuda M.2s ● Reverb G2 ● Win11Pro //// A10CII ● AH64D ● AJS37 ● AV8BNA ● C101 ● CEII ● F16C ● F5EII ● F86F ● FA18C ● FC3 ● I16 ● KA50 ● M2000C ● MI8 ● P47D ● SA342 ● SPIT ● UH1H ● Y52 Link to comment Share on other sites More sharing options...
AG-51_Razor Posted December 24, 2021 Share Posted December 24, 2021 Dunx, are you saying that the Tacans on the tankers worked normally by NOT using the AA position for the Tacan in your cockpit?? [sIGPIC][/sIGPIC] Link to comment Share on other sites More sharing options...

The first play of the mission, yes. After changing one of the tankers to use 30Y then the distance and tacan codes vanished for all stations.

Kang Posted December 25, 2021 Share Posted December 25, 2021 I know this might sound crazy, but I don't remember ever getting a range reading from a tanker's TACAN. Link to comment Share on other sites More sharing options...
VFA41_Lion Posted December 25, 2021 Share Posted December 25, 2021 you could always get both distance and bearing from a tanker TACAN, its been that way since at least the Hornet's release. This is almost 100% a bug, or ED forgot to mention in the changelog. Link to comment Share on other sites More sharing options...
johnnychemo Posted December 27, 2021 Share Posted December 27, 2021 That's pretty much what I found on my own investigation. You have to have the tanker use an "x" band and NOT select AA on the UFC to get the distance and bearing to show up now. Link to comment Share on other sites More sharing options...

Simply put: AA TACAN in fighters: range only. Tankers: Range and azimuth, because tankers have a partial array in the aft compartment to help jets line up better in bad visibility. Obviously fighters don't have the space to carry such a contraption. This is a bug and it impacts the Viper as well. 1 1 Link to comment Share on other sites More sharing options...

I think its just KC-10 that has bearing. 476th Discord | 476th Website | Swift Youtube Ryzen 5800x, RTX 4070ti, 64GB, Quest 2 Link to comment Share on other sites More sharing options...
Sn8ke Posted December 27, 2021 Share Posted December 27, 2021 IRL tankers don’t have bearing, mainly because they are unarmed and unescorted. AWACS can give you bearing/range over secure nets, or you can use your radar and SA functions.

VFA41_Lion Posted December 27, 2021 Share Posted December 27, 2021 (edited) how it works IRL and how it works in DCS are two very different things. in the sim, the mission editor allows you to have range and bearing for the KC-130, KC-135MPRS, and S-3B Tanker. (presumably the boom tanker one too but i never fly boom aircraft so i couldn't say for sure) Edited December 27, 2021 by VFA41_Lion Link to comment Share on other sites More sharing options...

MrWolf Posted January 1, 2022 Share Posted January 1, 2022 (edited) TACAN needs an array of antennas to perform some kind of spatial modulation that can reflect from which heading the receiving aircraft it's receiving the TACAN station signal. For distance no need of array because the distance it's obtained from the round trip time of an STATION broadcast interrogation pulse and a reply transmitted by the receiving transponder. https://www.globalsecurity.org/military/library/policy/navy/nrtc/14090_ch2.pdf So as someone already said: Big aircraft may be capable of having an array of antennas to perform bearing measuring (Ground stations of course) and distance, figher aircraft only capable of performing the distance measuring of the TACAN system. But it's dependent on the manufacturer of the aircraft maybe all those big aircraft doesn't have an array to perform TACAN bearing measuring. One thing is clear. All aircraft are capable of distance measuring with TACAN if they have a TACAN transponder and an antenna installed.

Chuck_Henry Posted January 2, 2022 Share Posted January 2, 2022 I've tanked with KC-130Js in real life. The default is "normal" A/A TACAN which provides only range. However, they have a separate TACAN on board that can provide bearing. You can even couple your aircraft's Flight Director to it, if so equipped. However, that particular device is often broken and the -130 crew has no way of knowing if it's actually giving you bearing. Their crew troubleshooting and asking us to verify if we were receiving bearing or not was like those old cell phone commercials, "Can you hear me now? How about now?" 3 Link to comment Share on other sites More sharing options...
El Chapo Posted January 2, 2022 Share Posted January 2, 2022 Same IRL experience as Chuck Henry. A/A bearing is exceptional. Most tankers only give a range. Bearing has to be obtained by other means... Link to comment Share on other sites More sharing options...
