When you send the AoB the PK's dial will snap to the new course and not move gradually. For TDC training, have you used the TDC training mission? That gives you a target of known course and speed so you don't have to worry about plotting. It's not complicated to set up the TDC at all. You change to the AoB dial, you move the triangles on the target course dial to the course you want, then you send that AoB. That's not procedurally difficult.

When you change the Target Course on the 3D TDC it will change the AoB entry dial to whatever matches that course, then when you send that AoB then the target ship will show as heading to that course and the triangles will all line up. Make sure you are reading the new course off the Target Course dial. If you are changing the target course on the 3D TDC and the AoB dial on the stadimeter is not changing, then your game has gone wrong, or if the AoB dial on the stadimeter is changing, but no matter what AoB you send it does not change the target's course, then that also an indication that something has gone wrong.

There's no trick to it, you just change it and send it. If you are doing what the video shows and your game does not respond in the same way, what is it that your game does that is different to the video? Can you change the target AoB through just the stadimeter pull out? If you cannot get the TDC to change the course or accept a new AoB at all, then I'd try a re-install.


Well what was it in the TDC that was different? If the target speed and target course were the same as you had entered, then nothing you entered was wrong and there should be no issue. The TDC will produce the same results with the same data every time, so there's no reason for your radar ranges to be off when you are in manual targetting mode, as nothing changes with the radar.

Are you sure you are following the tutorial exactly, E.G. when you enter a new range and bearing you reset the course as well back to 338? Ignore the white triangles drifting, as they are only relevant when you are setting new data to send to the TDC. They will normally drift, as the relative bearing changes and that is normal and perfectly OK.

EDIT: It's like riding a bike. Once you get it, you won't be able to do it wrong.

You can see my TDC info on some of the screenshots, the course and speed are correct. What else could I or should I have done?

Post up a screenshot of the TDC at the moment you fire the torpedoes and I'll see if I can spot anything wrong. Right after you enter the info it will all agree, so there must be something that's happening later on to make the solution innaccurate.

BTW, why are you entering the Raneg and bearing and AOB twice?

Nisgeis wrote...because that is what is says to do in the tutorial.

I just played it before I read your post and I used the stadimeter to update range and bearing shortly before I fired torps and I had 4 hits and 2 duds. It just doesn't seem like I should have to do that in this test mission. I will replay doing it as I have been and take that screenshot you suggested Nisgeis.

We'll get you working :DL.

Here are TDC screenshots of my latest miss taken right after I fired 6 torps.

Hmmm, your range is off by 200 or so yards, but the bearing is off by five degrees... how are you getting the bearing? Optically still? If so the bearing should be spot on.

I did notice something amiss with your order, you said:

What you need to do is to put in the Range and Bearing, AOB (course of 338), Speed, turn on the PK and then, enter the range and bearing again and the correct the course to 338.

If you don't turn on the PK before the second entry then all the relative motion of yourself and the target won't be taken into account and the solution will be off by quite a way if you don't correct it. The situation is made worse if you are travelling at high speed (heading directly towars the target) or you are changing course before the PK is truend on, as the relative bearing won't be right and the range won't be right and the. Giving it the second update ensures that it's more or less bang on.

The idea is to update the TDC every now and then with new information if it is different and try to use the differences to identify course and speed changes. The first setup is a problem though as the data will be old by the time the PK is turned on, so you need to update it with the fresh info.

Were you surfaced or submerged? What time of day? How fast were you going?

I am wondering if the target spotted you or the torpedo wakes and sped up to avoid your torps? I am having a particularly hard time with one merchant on my latest patrol due to him always spotting my torps.

It would be daylight clear weather for that training mission. I think it's a friendly target, so he shouldn't be worried by spotting you. Unfortunately you can't control what loadout you get in a mission, or I'd have loaded up with all electrics. I thnk Tubes #5 and #6 are electric though? I did hear rumours that the ships have hydrophones and can hear the torps.

That's a good point though... does the TDC indicator on the torpedo map track with the target before you fire. That's a good way to see if your TDC solution is correct or not. I forgot about it as I'm playing with map contacts off. If that black tapered line is TMO's version of the White X and line that is.

It's been a long time since I even looked at the Attack Map but if I recall correctly that line is a visual indication of the track your solution is predicting. If I am right (and I certainly may be wrong) then the range on the solution is off by 200 yds (like you already noticed).

Strange though that if the contact is 200 yds closer than the solution then shouldn't the torps miss ahead rather than behind?

3D TDC and course
 

My mod was screwed up to the point that when I tried to disable it, it would not do so. I gave up and will reinstall the game. That should be the solution to the failure of the target to snap to the course setting.

I'm not sure why the line looks like that. I'm running TMO, and I've got a white X and line.

If the target was only closer. The bearing appears to be off a decent amount as well.

John Channing wrote...I initially submerged to 40ft. it was whatever time of day you set up the test mission for, I don't remember but it was daylight. I started off going full speed and decreased to either 2/3s and or 1/3 depending upon how close I was when I thought about it. The target mostly never spotted me unless I forgot to lower my depth as we got closer. I would generally go to 48' next(so I could keep using the radar) and then to 58' as he got closer still. I have run this mission probably a couple of dozen times or more in the course of trying to figure out what I was doing wrong. I am not a modder, the only thing i have "modded" at all is the pics on the walls of the Captain's office but I can see where this process would get old. The only time the target spotted me was when I forgot to lower my depth as he got closer and it was obvious that he was aware of my presence. He definitely wasn't friendly though, he was firing at me when he did spot me. I didn't include results for anytime that the target spotted me I just reset and started over.

Well, hopefully I have been of some use as a tester and It appears the tutorial needs to be modified. So it would appear that I am the first to try the XRT5 TDC Training Part 1 mission. I am off to try again.

Send money
 

Do I get compensated for my time?

I reloaded my 3d TDC. I am practicing on the 3rd practice mission. The 3d TDC is the last mod enabled. I disabled the Gate interior fix to be safe. I now have the course down via plotting with map contacts enabled.

I have tried to set course via the triangle on the 3d TDC target dial. I set course to 115 degrees (or 118 degrees, I forgot?) but the dial on the right does not match, nor does the ship snap to its new course. I set the new course when the stadimeter is showing the Aob dial. I have tried setting course with TDC off and with radar turned off. I have tried it with TDC on and radar turned on. I have tried it with periscope locked on the target and with periscope unlocked. What is wrong?

Also, why measure speed? Can't we just hit the little button on the speed dial on the stadimeter?

Hallelujah Put 4 cases of beer in the cooler! Range and bearing, AOB, speed, turn on the PK and update range and bearing leaving PK on.
