Mastering the TDC

Linklinker · 06-02-07, 10:31 PM

Well I think I have finally mastered using the TDC. I still need more practice, but it feels so good knowing that shot I just made was done purely by myself without having the computer do all of it for me.

Although I was wondering how I input the bearing into the Gyro angle. The only way I can seem to do it is by telling the sonar man to send it to the TDC.

Also why is it that my Sonar man seems to not be able to find ships on his own. I mean its sort of his job to turn that handle and listen. I sometimes have to go over to the station and reaquire the target. Mabey its the RFB mod.

There is one other thing thats been bugging me since I started playing the game. I have all the realism settings at 100, but I have noticed that the deckgun still has the crosshairs on the screen. I don't think that the guy operating the deckgun back in WWII had a floating crosshair in front of him. :hmm:

Well anyway being able to input my own data into the TDC is really fun.

From what I understand, bearing is sent to the TDC when you send the range. Just take another range reading and your bearing will be updated.

You're absolutely right...I find that the game is so much more rewarding when you do all the targeting yourself. Good luck and sink 'em all!

I start with the general estimate on speed/AOB. I get the range then update. This will feed everything into the TDC. Start your TDC. You can at this point reset all individuly at this point. Make a lot of scope checks and readjust as needed. I make my final range/speed/AOB about 1500 yards out. I fire between 1200-1000 yards. If you use the TDC correctly, there is no need for the chronometer. The PK is just that, a position keeper. If the PK does not look like anything you see visually, it is not set up correctly. This is why as many observations as possible to dwindle down the range/AOB/speed and make it as accurate as possible. Once that PK is exactly set to what you see visually, you are assured a hit. After my final small adjustment if any on the TDC/PK, I drop scope and wait until I'm in firing range. I fire, sit and count the seconds. Very satisfying to here the explosion and the sonarman say torpedo hit.

After the first hit, scope up to see my booty get hit some more. I send a spread of three torps always.

I sometimes use the TDC on its own without plotting, tools or and calculations of speed (on 100%). I am still trying to perfect this, but as it all about estimation, its pretty hard.

Input best guess data for AOB, Speed, then input accurate range - eaither manually, by sonar or Ctrl V -nearest visual contact gives range..

Then simply compare bearing of target in periscope to bearing computed by TDC - over a period of time. Reinput data with a faster speed if the TDC is lagging behind the peri bearing. When you get it right, they will match and you can shoot. Its not perfect, but is ok for those rushed shots on 100%..

You are getting the idea here though! When the PK is lagging or advancing to your visual sighting, it is off. Usually your speed. The AOB on the PK should remain constant to your visual AOB. From a distance the PK AOB should move very slowly. If it is dragging or advancing AOB but the AOB of target has not, then the speed is off. Drop or advance two kts (depending if it is dragging or advancing). Let it run again and see how you comparing. As you close the target, the AOB will start to move more quickly but the PK and visual should look identical. If so, you are dead on speed calculation. I do not concider sending torps until 1200-1000 yards. By that time, you have had about 15-20 minutes for observations and adjustments. It is a neat gadget when you figure out it's inner workings!
