GWX3 Torpedo range and fuse questions

[Mopy]

Only within 2000m! I have trouble hitting things at 600m

I can use the notepad method without a problem, but I don't think I understand the manual inputs in the F6 screen yet. Speed and range is no problem, but AOB seems to keep changing along with bearing, despite the fact I haven't touched speed or range.

Nevermind, I'm sure I'll work it out. Still plenty of patrols to go yet. At least I seem to have the staying alive and evading depth charges worked out now.

If you have your TDC turned "on", the bearing and AOB dials will rotate as the scope/UZO follow the target, which is normal. That information will remain accurate as long as your sub or the target does not change course. If your sub or target changes course, you have to turn the TDC off and update the AOB once sub/target is on the new course.

Range and speed remain where you set them until you need to adjust them.

Bearing is not set manually. It is tied in with your UZO/scope and changes as you rotate them.

Hope this helps.

That does help, thank you.

Just to be clear (sorry for all the questions) - when I enter range, speed and AOB, I should already be in a position to attack at the point where the the target will pass in front of me.

So - if I then say, follow a course change from the target, I would have to re-enter the details on the TDC (F6) screen despite the fact range, AOB and speed would all still be correct?

And - If I were floating around still on my way to my planned attack point and was not facing the correct direction yet, and at this point entered AOB of 90 degrees, when I arrived and faced the correct direction, any data entered would be useless?

Finally - The bearing setting (which I understand does its thing automatically now) is attached to the sub compass, and this is the reason that AOB cannot simply be set to 90 degrees at any time, because this would ultimately skew the results if not already in the desired position?

If all three of these are correct, then this is my problem. I was missing the connection of the other settings to the bearing, assuming they were independant. I have been setting AOB to 90 degrees before getting into the firing position, and wondering why on earth the bearing indicator isn't pointing at around zero degrees when I arrive at my attack location, which of courseon changing, changes AOB at the same time.

This would also explain why the notepad method was getting constant hits, yet the TDC screen was not, as using the notepad I was re-calculating having arrived at my final ambush point.

Think I just had a major 'duh' moment.

Assuming the above is correct, I'm off to try it now.

::edit - sorry, I forgot to add. I did do a manually targeting tutorial, but only with the notepad, so I wasn't flying entirely blind.

Try this-one of the best tutorials on manual targeting:

If I understand your question, the target changing course will cause the actual AOB to change and will need to be updated once he settles in on his new course. Speed should remain constant, and of course range is always changing and needs to be set accurately at the time of shooting. (Unless you are shooting with a 0 gyro angle and an AOB of 90-it will make more sense after reading the above tutorial-I don't want to confuse the issue yet ).
A course change by your sub will not change the target's actual AOB but will make the AOB setting in the TDC inaccurate and will need to be reset.
The reason is if you move the scope/UZO, the bearing to target changes which changes the AOB setting automatically in the TDC.

To see this, with the TDC turned on, move the scope/UZO and the setting in the TDC will change.

And - If I were floating around still on my way to my planned attack point and was not facing the correct direction yet, and at this point entered AOB of 90 degrees, when I arrived and faced the correct direction, any data entered would be useless?

Yes. Any course change by you or the target makes your AOB setting in the TDC useless.

Finally - The bearing setting (which I understand does its thing automatically now) is attached to the sub compass, and this is the reason that AOB cannot simply be set to 90 degrees at any time, because this would ultimately skew the results if not already in the desired position?

You are correct. I think it will definitely make more sense after you read the tutorial.

I hope I have not totally confused you and have answered your questions.
Feel free to ask as many questions as you want. There are a ton of people who are more than willing to answer them and may make it even clearer than I can.

Thanks Sharkbit, very useful. Six consecutive single merchant sinkings from various ranges as a result. And I actually understand what's going on now, and why, which I hear can often be useful

Thank you for all your help, and the others that answered my above questions too. The result was 80% failure rate when I started the thread -> solid success rate (6/6 ships, 12/12 torps dead on exactly where I wanted them to detonate)

I suggest to change the torpedo depth to 3 or 3½ meters.

Heh sorry, my bad choice of words. Dead on meaning they hit where I wanted them to It's been deadly calm for ages now, so I'll save the impact for rough seas or long distance shots as I understand is the correct thing to do from earlier posts. No problems with the magnetics yet, though I am still using T1's.
