Megagoth1702 Posted November 27, 2011 Share Posted November 27, 2011 (edited) Hey folks. I am currently reading the book Warthog - flying the A-10 in the Gulf War. There is a chapter where they say the pilots used TACAN to find eachother in the low-vis conditions. I tried that with a buddy of mine one day, he was still on the ground starting up his engines, I was in the air. We both went on 20X and did AA T/R, normal TR but neither of us was able to get the signal. Does it even work in the sim? I mean it seems to work in real life if the people wrote about it. Thanks in advance. EDIT: Also a small question which is not worth opening up a new thread. I kind of forgot if they said it in the book or not... But at what altitude did the A-10s usually fly over the atlantic? I read that a few times some of them ended up flying through a storm and I asked myself - why not fly at 15k-22k? Above the weather? Is that too high for the A-10? I mean I just did a test flight, 400miles, 23k, no problem. So I was wondering what altitude the people used to cross over the atlantic or what altitude they use for cruising in general.

GGTharos Posted November 27, 2011 Share Posted November 27, 2011 Sure it works, but it needs to be 63 channels apart. Being on the same channel won't work. Also, storms can easily reach up to 50-60000'.

Eddie Posted November 27, 2011 Share Posted November 27, 2011 As GG alluded to above, for TACAN Yardstick you need the flight lead and the wingman(men) to select TACAN 63 channels apart from each other. In addition you should be on Y for AA TACAN rather than X. So in your situation one of you (flt lead) would select TACAN AA T/R Channel 20Y, and the other(s) (wingman) would select channel 83Y. And FYI, TACAN yardstick will only give you range in the A-10, not bearing. It's very useful when flying combat formations to check that you're holding the correct distance.

Surely that gives you a bearing doesn't it. Always remember. I don't have a clue what I'm doing Link to comment Share on other sites More sharing options...
Eddie Posted November 27, 2011 Share Posted November 27, 2011 Yes, but what has the tanker got to do with TACAN yardstick between two or more A-10s?

Jona33 Posted November 27, 2011 Share Posted November 27, 2011 Ohh, I thought you meant that the TACAN in the A-10 could only show the range ever. Always remember. I don't have a clue what I'm doing Link to comment Share on other sites More sharing options...
Megagoth1702 Posted November 27, 2011 Author Share Posted November 27, 2011 Oookaaaay... Now I realize that I lack understanding the TACAN system... The difference between X and Y channels seems to be, as far as I learned now, that in Y you don't get the bearing. Ok, let's say FL is on 20Y and his only wingman is on 83Y. What will happen? Will they both get the range between eachother? What if there are more than 2 planes using this? I always thought it's only possible to get tacan working by having the same channel for everybody, like radio. I mean, sure there would be problems with more than 2 planes, but I just thought... Ah well. Too high for me, haha. Unless someone does a baby step explanation. Wikipedia is friggin hard as well.

The difference between X and Y channels seems to be, as far as I learned now, that in Y you don't get the bearing. Y is used for airborne TCN stations and X for ground stations. At the moment Y doesn't work for tankers, I'll be fixed in an upcoming patch. Ok, let's say FL is on 20Y and his only wingman is on 83Y. What will happen? Will they both get the range between eachother? What if there are more than 2 planes using this? Yes, both aircraft will get range to each other. If there are more planes using it, for example a 4 ship flight, lead would select 20Y and ALL wingmen 83Y. All 3 wingmen would then get range to the flight lead, lead would get range to the closest (and therefore strongest signal). I always thought it's only possible to get tacan working by having the same channel for everybody, like radio. I mean, sure there would be problems with more than 2 planes, but I just thought... TACAN doesn't work like the radio. Each TACAN channel actually uses two frequencies, one for transmit and anther for receive. The reason you need to separate by 63 channels is that when you do this the receive frequency will be the same as the other aircraft's transmission frequency Ah well. Too high for me, haha. Unless someone does a baby step explanation. Wikipedia is friggin hard as well. Is that clear enough? If there is anything else you don't understand or need clarifying ask and I (or someone else) will explain.

Megagoth1702 Posted November 27, 2011 Author Share Posted November 27, 2011 Ah, thank you, I get most of it now. 2 frequencies... Now that's interesting, thank you! Stuff makes sense now. So Y and X work the same, the only difference is "use Y for planes, use X for ground"? Is there a way to have TACAN set up for A-10s so it will show bearing AND distance? Just like a tanker's TACAN?

Megagoth1702 Posted November 28, 2011 Author Share Posted November 28, 2011 Roger, thanks. Also a small question which is not worth opening up a new thread. I kind of forgot if they said it in the book or not... But at what altitude did the A-10s usually fly over the atlantic?

I mean I just did a test flight, 400miles, 23k, no problem. So I was wondering what altitude the people used to cross over the atlantic or what altitude they use for cruising in general. Yeah, still that tiny question about general realistic traveling altitude. Not talking about storms here, just how high the Hogs usually go.

GGTharos Posted November 28, 2011 Share Posted November 28, 2011 That would be a flight schedule - ie. you get your -1, figure out the most efficient altitude to fly at. Hogs have done combat sorties at 29000' over Kosovo due to AGL hard deck limitations. Transit altitude may or may not be that high, I don't know - it really depends. If they are transiting while carrying ordnance and in particular a belly tank, I'd expect them to be under their ceiling of about 23000' for those weights.

bartleby Posted November 28, 2011 Share Posted November 28, 2011 Is there a way to have TACAN set up for A-10s so it will show bearing AND distance? Just like a tanker's TACAN? As mentioned, the hog only does range. From my understanding of how TACAN works, transmitting bearings takes a lot of power and makes a lot of heat, and I think most small planes don't bother with it.

Megagoth1702 Posted November 28, 2011 Author Share Posted November 28, 2011 Yeah well if the ADF worked in the sim (more support for TARS?) I would not have the need for heading in TACAN, hehehe. :) [sIGPIC][/sIGPIC] System specs:2500k @ 4.6 GHz 8GB RAM HD7950 OC'd Win7 x64 Posting tracks to make your DCS better - attention bump incoming!

From my understanding of how TACAN works, transmitting bearings takes a lot of power and makes a lot of heat, and I think most small planes don't bother with it. ...uses a lot of space and adds a lot of weight. The DME part is included more or less for free with the basic DME capablity though. Not only small aircraft skip the bearing capability. In fact, the KC-10 is the exception for including it, as opposed to e g the KC135. The latter isn't exactly your average spam can. :) The difference between X and Y band DME (and the ranging part of a TACAN is a plain old DME) is only the pulse spacings in the signal - a way to double the use of the frequency spectrum. No technical reason to limit airborne use to Y band. However, you want to make sure you're not stepping on land-based navaids. ----- Introduction to UTM/MGRS - Trying to get your head around what trim is, how it works and how to use it? - DCS helos vs the real world.

Jona33 Posted November 16, 2012 Share Posted November 16, 2012 They crossed at 18,000 although in the storm one of them ended up with only backup instruments and ended up at 23,000 feet and climbing at 5,000 a minute because of an updraft.

Hot_LZ Posted September 23, 2013 Share Posted September 23, 2013 X is used primarily, for both air and ground. Y can also be used for air and ground. It doesn't matter at all. The standard is X, so just use X for air to air tacan. If you want a third aircraft to get range distance from the other two, be sure to have that third aircraft set on tacan RECEIVE ONLY.

Hot_LZ Posted September 24, 2013 Share Posted September 24, 2013 Saw your guide. First of all, I would just use X instead of Y, it's the standard. Also, most of what's in the guide maybe works in DCS (haven't checked it), but it's not realistic since it won't work that way in reality. Any 3rd, 4th, 5th etc aircraft would have to select Air-to-Air TACAN RECEIVE ONLY, like I said before. If you don't do that, the signal would interfere and render all distance measuring going on between the channels unreliable and useless. It's not true that the system just picks the 'strongest signal'. That just doesn't happen. Link to comment Share on other sites More sharing options...

Hot_LZ Posted September 24, 2013 Share Posted September 24, 2013 Oh ok, I thought 476th was one of those squadrons which did everything realistically, instead of exploiting ingame errors/flaws. Disregard my post then, except for the people who like to know how it really works. Link to comment Share on other sites More sharing options...
Eddie Posted September 24, 2013 Share Posted September 24, 2013 There are many areas where DCS does not match reality. Knowing how it really works, or wanting to do things as realistically as possible has little to do with it, you have to work with what can be done in the sim, and also in such a way that people without real world experience and access can learn and understand the material. And frankly 100% accurate AA TACAN procedures isn't high on the list, when compared to weapon delivery and tactics amongst other things.
