Stoianm,can you tell me what mod you are using that gives you the graded center cross in your video about the ROABF?

you need TDW UIs and Manos Scope

Thanks bud,and thanks for your hardwork making Silent Hunter better and better.:salute:

Hi!

Yesterday I try to shoot with the aft tubes and the RAOBF. (After a direct hit, Rawalpini was by survivor mode... and nothing fore torpedoes...)
Screenshoot for it:
https://picasaweb.google.com/Zs4zet/...53411877505666

I beleive, the standard RAOBF calculating method not good for the aft tubes, but I don't know that I how get the correct AOB value.

Ship-book-length = 147 m
Optical length = 28 click
Ship range = 540 m (this is correct).
I get AOB = 15 deg, but I see on the TAI it is 69 deg.
(Currently was Manos scope)

How I get the good value from RAOBF?

Thanks!

Hi Zs4zet:salute:

Well done you are very close to mastering the RAOBF:yeah:

In your pic - you are using scope zoom x1.5 (normal AOB is at x6 zoom, so x6 divided by x1.5 zoom is 4)
So you need to x your 28 clicks by 4
28 x 4 = 112

Now look at 112 and you will see it is AOB=70deg:up:

Ohhh.... very thanks! :salute:

The another more difficult situation - shoot after the ship (AOB > 90 deg) - read in your tutorial, I must do: 180 deg - AOB. This is enough? This was 2x, in different situations, but not got good value. Sure, I forget something, too....

The most difficult situation, shoot after ship and with aft tube, never arose till yet.

Yes - If ship is moving away from you it will have an AOB higher than 90deg.
The RAOBF only goes up to 90 deg.
So this is when you would take away your result from 180 to give AOB

Thank you! The I will use it with an occasion nearest.
:salute:

I try shoot after the ship...

Set ship length, range is ok, set the optical value, but I don't see the AOB value.
I read this from TAI. That is 102 deg. I set it too.
I rotating to periscope to Gyro 0-0, and a crosshair is wrong direction.

I try to 180 - 102 deg the error is only smaller.

(The scope multiplier is x6, the AOB is positive - right side of ship)

I always found this...(only once was good, but I don't know, how I do that; but I remember the AOB was a good place, and I did 180 - AOB, and set that to TDC, and the Gyro was good.)
I have some big mistake here, but I don't see what is that. Sorry I know, I do something badly...

Not sure what you are trying to do here.

For the RAOBF in image 1 - it looks like the range is wrong.
When a ship is at 90deg AOB - it will appear in the scope at its largest possible size.
If the ship is rotated so that AOB passes 90deg to 100deg - the ship will appear smaller in size - so the AOB readout in the RAOBF can not be greater that 90deg

So this is why I think either the range or ship length is set wrong:hmmm:

Thanks!

I try 10-20x this situation, but I received the same one, after I was angry next, and kill them by the simple, numbers in circles method.

This was not a ideal test environment (but I not prepared for testing...)
- the place was in the crossroads of ship-routes 6 ship arrived from 3 direction (in pair), and they modified their direction and their velocity.
- the see wasn't very rough, but was big waves.
- under the aiming I always disconnected from the ship.

Tomorrow, I will be testing in your tutorials, with standing ships and without big waves.

Hi Trevally!

You're right.
I get wrong range value, if measuring badly. Does the weather have an effect on the visibility of the ship? The same ship at two days, I measured it for two kinds.

The RAOBF rings working correctly, I get good AOB (if the range is correct).

But, 2 days I looking the good targeting method for the away ship.
I get the values from RAOBF and clock, and I type then the XO's dialog, working for the coming ship, but not working the away ship.

I try the another (AOB=90 deg) tutorial method.
- After the get the values, disable follow target, after unlock.
- Set the scope to 0 bearing.
- Press red button.
- Set range, AOB, and speed rings. (I set correct AOB +/- side.)
- Press green button.
- Set Gyro to 0.
And if the ship come to me, this is good. If the ship away from me, not.
If the AOB values between 90 and 180, the gyro go (aiming) after, and not before the target.
What do I badly? Please, if have you time, write that, what is the good targeting order step by step.

(I saw the gyro working only, if I set the any speed value. I don't try to shoot not moving ship.)

Thanks!

Hi Zs4zet:salute:

It sounds like you are setting the AOB to the wrong side.:hmmm:
If it is set to the starboard side, but it should be the port side - the TDC will think the target is travelling the opposite direction.
This will cause the torp line to be behind the target.

Hi!

I know this... this was my first thought.

I did screenshots for this:
https://picasaweb.google.com/Zs4zet/...63367302574802
I got the datas from TAI, not for the RAOBF. They are correct values.

After I move to gyro 0:
https://picasaweb.google.com/Zs4zet/...63366598355282
The red line shows the direction showed by TAI, and the green line would be the correct.

If I set the gyro not to 0 but I set gyro to 90 deg, I get the good line, I shoot before the ship.

What I do badly?
My aiming working correctly, if the ship come to me.

For image 1 - your setting are correct. If you move your scope to the target and fire - your torp will hit:yep:

In image 2 - your setting are also correct. But by setting your gyro to zero - you must wait until the ship passes you scope and then fire. To get this to work - you need to place your boat in front of the target - then wait for it to pass through your scope:up:
