Thanks a heap RDP, I'm starting to get the idea, so far still doing theory, will attempt practical soon (I get butterflies when pressing the SH4 Icon).:yep:
I thought I'd stick to Metric but noticed the Attack Data Tool is still imperial.:-?
Question: Can you change range etc and send to TDC with PK on?

Well I still can't get this, I have tried dozens of times with the Torpedo school mission & cant get this to work, the torpedo's allways miss by 200 yards to the rear!:damn::damn:
Please tell me the steps I should be doing to get this mission complete.
What I am doing is:
1) setting speed to 1/3rd, raising scope & locking target.
2) finding correct ship on Recognition manual & clicking the tick box.
3) using stadimeter to get range & sending to TDC.
4) lower scope for 10 seconds, raise scope & lock target, use stadimeter to get range & send to TDC again.
5) select speed on the tool & click on Esimate speed, comes 90% of the time as 5 knots, send to TDC.
6) goto nav map to get idea of AOB, go back to scope & set, usually around 85 degrees to Starboard.
7) lock PK.
Fire & misses by a mile!

Anyone here that can do this mission please tell me where I'm going wrong please, step by step.:-?

At 30 deg the visible length of the ship will be half, at 45 deg it will be about 2/3 or 70%. Get a feel for that and you can work the AoB to some more exact...plus if your in close(about 1000yds) just getting the AoB is good enough.

I tend to look for/wait for specific AoBs that Im good at eye-balling and set/check my solutions then.

That may work over time, but not at this stage, the ship changed course as you can see & I did actually change the AOB before setting the PK on. I hit the "z" key but didnt change to silent running, don't know how he saw me, if it was my scope then how the hell can I get the data, this is most frustrating!:cry:

From the picture I can immediately tell you two things: Your target speed in TDC is zero(notice the yellow SPEED 00 below the target wheel), and target range is way too short. Once you have used the estimate speed function, remember to click the send to tdc button. Similarily, it MUST be done after you have scrolled the speed wheel manually.

A few words on AOB: At distances as short as that you can usually eyeball it well enough, but getting the precise AOB is very easy by using just the TDC, provided that you know the target course. Screw the map for getting the AOB, it's too slow and will be a few degrees off by the time you input it to the TDC(though a few degrees does nothing if the distance is anywhere under 2000 - 3000 meters). As many have already said, even the ingame TDC has the whiz-wheel functionality and a lot more to it. The estimate speed function also gives you the target course, or you can get it via the map. Whichever way you use, the target course is important at this stage, not the AOB. Once you have used the estimate speed function to get a speed AND sent it to the TDC, enable tdc. Then go to the AOB wheel, eyeball an AOB and send it to the TDC. It doesn't need to be even nearly correct at this point, within 45 degrees is easily good enough. Then you look at the target wheel(the upper one) on the TDC and keep turning the AOB input wheel and sending it to the TDC until the ship on the target wheel has the correct course. AOB is what it is, just look at the course. Course is the outer ring of numbers. Once your target wheel is on the correct course, you would take one last range and bearing reading and send it to the tdc, then re-check that the target wheel is on the correct and adjust if necessary. Then you could fire. This is exactly what WernerSobe does in the video, and it gives you the correct AOB every time, provided that your course is correct.

edit: When sending range, remember to click the send button TWICE just in case. In certain conditions it only sends the bearing on the first click and the range on the second, but I can't remember when this occurs. Clicking always twice eliminates that problem.

Thanks I need all the help I can get, after estimating the speed & showed as 5 knots I pressed the red send to TDC icon, so I fail to know what happened!
What do you mean, when the speed is estimated the dial automatically points to 5 knots, I then press send to TDC button, isn't that all that's required, is this wrong?:-?
I don't know how to get the range correct with the stadimeter, I zoom in for a better view and align the waterline of the ship with the top of the mast, left click to release it then click the red send to TDC button, so I fail to know what I'm doing wrong.:doh:
That may explain that!:dead:
How?
Where is this displayed?
By the time I do all this the ship would be long gone! I will try to practice the steps in the navigation school.:yep: 2 days I have been trying this & both times I've ended up with a head ache!:cry:

That's the correct way. Click that button a few times as well, just to be sure :)

That's also correct. One thing you might be doing wrong is the identification. Your target is a Mogami Heavy Cruiser in the torpedo training mission. With map contact updates on you can also easily check your solution from the attack map once the TDC is on. See the white cross+line about halfway between you and the target in your screenshot? That's where your TDC thinks the target is, and it should of course be on or near your target for the torpedoes to hit.


Look at the ship and plug in your best estimate of the AOB via the AOB input wheel. For example if the bow of your target is pointing right in your periscope, you input 90 degrees starboard(right) as the AOB. If the bow is pointing left, then you input 90 port(left). I assure you, you'll do a lot better estimating it yourself than sticking to these guidelines. A rough estimate is good enough at this point, since we'll be updating it shortly anyway.

It's shown in the message bar along with the speed.

It doesn't take more than a few seconds once you get the idea, which you can see in the WernerSobe video. As someone already said, the torpedo training mission is not the best place for practice, since there's very little time to act. The target starts so near you, that you really need to know your stuff to hit it before it's way past. I'm currently at work, but once I get home I can do you a guide with screenshots that walks you through the torpedo training mission.

Hi Fincuan, I have actually been setting the correct ship ID, one of my biggest problems is that my nerves go to pieces trying to rush everything, I will have to relax more, I do wonder though how I can be this bad (thick)!
That would be something!! I should probably give this mission a miss but I hate being beaten! I'm stubborn, I see that everyone else can do it so why not me!:lol:
Thank you, that would be great,:yep: sorry to put you out though!!:oops:

Just to clarify this a bit: Inputting the AOB once you know the course only takes a few seconds, but it takes longer to gather the data required to find out the course :)

Das Tutorial
 

Ok, here we go as promised. I'm using TMaru 1.7.2, RSRDC and a few other mods, so things might look a bit different, but they still function all the same. Because of TMaru I had to remove the damn plane from the mission, since it would start strafing me and altert the Mogami :lol:

1. Identify the target. In the Sub School torpedo training mission we have a nice, fat Mogami Heavy Cruiser in the sights.

2. First observation. Lock the ship, get the range with the stadimeter and click send to tdc ONCE(Confirmed, once is enough). Lower the scope after clicking "send to tdc".
   
3. Wait... I waited a bit over a minute. The more you wait the more precise your readings will be, but then again you don't have much time in this mission. Now is a good time to set up the torpedoes and open the tube doors.
   
   
   
   
   
   
   http://staufa.bounceme.net/files/tutorial/image02.jpg
   
4. Second observation. Again remember to click "Send to tdc" only once. Lower the scope.
   
5. Go to the speed dial and hit the "Estimate speed and course" button
   
   
   
   
   
   
   
   http://staufa.bounceme.net/files/tutorial/image03.jpg
   
6. Send the speed(9 knots in this case) to the tdc by clicking the "Send to tdc" button once, and note the course from the message box(101 degrees)
   
   
   
   
   
   
   http://staufa.bounceme.net/files/tutorial/image04.jpg
   
7. Go to the AOB input dial and raise the scope. Turn the wheel to what you estimate as the AOB and click the send "Send AOB to TDC" button. As you can see, I estimated the AOB to be about 78 degrees starboard. Lower the scope.
   
   
   
   
   
   
   http://staufa.bounceme.net/files/tutorial/image05.jpg
   
8. Look at the target wheel(upper left corner). That wheel shows the target as seen from our sub(the bottom wheel), and our sub is ALWAYS at the bottom. By looking at where the bow of the target(zero on the inner wheel) points on the outer wheel, we can now see what the TDC thinks as the course of the target. In this case the TDC has calculated that an AOB of 78 degrees starboard would mean that the target's course is about 82 degrees. From our two observations we, however, know that the course is really 101 degrees. Time to make some adjustments.
   
9. Still looking at the target wheel, we can see that a course of 101 degrees would require the bow of the miniature ship to point more towards our sub, meaning the AOB should be smaller than the 78 degrees I previously estimated. To achieve this, I roll the AOB wheel until the marker at the bottom shows something smaller, 50 degrees in this case, and click send to tdc.
   
   
   
   
   
   
   
   http://staufa.bounceme.net/files/tutorial/image06.jpg
   
10. After our re-estimated AOB the target wheel now shows the course as 110 degrees, which means that we went too low with the estimate of 50 degrees. We now need to roll the AOB wheel back a few degrees, and send it to the tdc again.
    
    
    
    
    
    
    http://staufa.bounceme.net/files/tutorial/image07.jpg
    
11. There we go! The target wheel now shows a course of 101 degrees, which is what we wanted all along. We can now enable the tdc. Note that the screenshot is actually taken after the next step.
    
12. Make one more observation, and again adjust the AOB until the target wheel points to 101 degrees. If you have map contact updates on and the periscope is up, you can easily check the quality of the solution from the attack map. As you can see, the thicker end of the small black line, which is where the TDC thinks that the target is, is almost on top of our target. When we observe it for a few seconds, we can see that it also stays there. This looks like a decent solution, so I decide to fire. I make one final observation to get the latest range and bearing, and again adjust the AOB as we have done above a few times already. Then it's time for... ROHR EINS, LOS! ROHR ZWEI, LOS! ROHR DREI, LOS! ROHR VIER, LOS!
    
    
    
    
    
    http://staufa.bounceme.net/files/tutorial/image08.jpg
    
13. KABOOM! Since these are early-war american torpedoes, the result was what we expected: two duds and one with a gyro problem sending it off to the right.
    
    
    
    
    
    
    
    http://staufa.bounceme.net/files/tutorial/image09.jpg
    
14. A final check of the attack map after the torpedoes have hit. As you can see, the TDC's marker is still almost on top of the target, which means that our solution was spot on.

A few things to remember:

• Keep the scope up as briefly as possible
• Click "Send to TDC" after changing anything
• Remember to enable the TDC after you have all the data.
• Adjust the AOB after each observation
• Make one final observation right before firing

Have printed this out, will study first, then chew my nails!:lol:
Will report back with good news soon I hope!:yep:
Many thanks again.:up::up:

One last queery before I try my luck!:yep:
Do I have to turn the TDC off first?:)

Re-read Step 11.

Nice post\explanation Fincuan :yep::up:


RDP

Thats right it was previously off whilst doing Range, then turned on, now the range is to be done again, do I have to turn TDC off do range again (use stadimeter & send to TDC) then turn it back on.:-?
