It works too
 

I agree it is, but I check on the Nomograph for a conformation. Don't us sonar except for single target.

getting mad again!!!

Ok.. SO I have the line for the course..

right.

how do I input this on the TDC again?

I know how to do it, but how am I reading it.

Because I found the line to be a course of 325 based on the compass from the ruler and when I put 32 on the AOB top right dial, its not even damn close!!

OK, You didn't read my "High Realism Tutorial" did you?!

Page 11, Chapter 12......you have a line drawn from the sub, along the relative bearing you've spotted the target on. That's line one. You say you have the target tract line (the targets course) and it's at 325 true north bearing. That's line two.

You know the target course bearing because you took two different relative bearing readings of the target and figured the range to target in both readings. You marked the spots on the map and drew a line through the two of them. That's the targets course path/tract; or you simply drew a line through the targets icon.... from the rear of the ship, out through the icon, simulating the targets estimated path/tract. Either way you have 2 lines drawn on the map. One from the sub following the targets relative bearing from the sub (line one), that intersects with the estimated targets tract course (line two).

Now, use the Protractor Tool (that's the tool that looks like a square....in the left/bottom most spot of the map corner). Left click on your subs relative bearing line, and pull a line along it's path until you reach the intersecting target course line. Left click at the intersection. Now, turn down the target course line and follow it for a bit, in the direction the target is traveling. The degree reading at the intersecting point is your angle on bow.

To input the AoB, you'll take the degree amount you found and move the AoB dial on the Attack Data Tool to the same figure. Click the red "send" button, the PK/TDC is updated. A quick point, if the AoB is say 29 degrees, move the AoB Dial to 2.9. The dial is set up in tenth's, 30 degrees is 3.0, 90 degrees is 9.0. Also, don't forget to mark whether it's Port or Starboard.

Next time read the directions. :D

Thanks.. but I was told I really didn't need to use the protractor, drawning a line from my sub to the target, I haven't and it seems to work.. what I don't get is this!

Here is the course line of the ship, I put the compass over the line..

What is the course of this ship?



Now.. How do I enter this on the TDC, top right dial, right?

http://i618.photobucket.com/albums/t...ps1d657fc1.png

Can't read your SS, old eyes, but if you mark two points the ship travels, then drag the compass between points to get the course, just enter the course using the outer markings on the left AOB wheel. You do that by adjusting the AOB wheel on the right by clicking it until it matches course or if you use EZ AOB, you can spin the wheel. Simply, the ships course relative to your sub is a perfect AOB.

Most people do the 3 minute at the same time, get speed and course. As long as it doesn't change, you'll just need a good range.

Use the protractor!!

Depending on which direction the target is going in your first picture, the course bearing to true north is read closest to the target ship as you pull the circular protracter away from the target starting point. In your picture, if the target is traveling toward the top of the map (North), the course bearing is 335 degrees. If the target is heading towards the bottom of the map (South), the target course bearing is 155 degrees. All you've given us is a straight line with the circular protractor sitting on the line. It makes a difference where the target is in relationship to which side the protractor is read. You always pull the protractor away from the sub or target ship, going in the direction of travel. The protractor is always read at the degree mark that's nearest the ship you've just pulled away from.

Neither of these degree figures are the Angle on Bow.

The bearing found with the circular protractor is the targets course compared to true North.

You don't. There's no place to enter the targets true North course bearing. This gets figured out from the Position Keeper/TDC by knowing what direction your sub is traveling, and the inputs of target AoB and the targets relative bearing to the sub.

You'll need to find and enter the targets Angle on Bow.

To do this, you need to use the square protractor (that's the brown triangular tool at the bottom left of the map). In your second picture the relative bearing shows the target at 290 degrees. Take the 290 degree relative bearing to the nav map. With the circular protractor tool, draw from the center of the sub out to intersect with the targets course bearing line. Again, make sure the 290 degree mark on the protractor is matched with the line your drawing away from the sub. Now, you have the two lines I was talking about earlier. The subs relative bearing "sight line" to the target, and the targets course bearing to true North. Choose the square protractor and you get an icon that looks like a compass you draw circles with on paper. Set the tool on your subs relative bearing line, and draw it out to where it intersects with the targets course line. Left click at the intersection, then turn down the target course line and follow it for a bit. The degree figure that's at the intersection of these two lines is your AoB.

It's this figure.....the angle in degrees between the two lines.....that you enter on the Attack Data Tool (it's what it's called!!), the tool at the top right of the scope station. Find the AoB dial, it's one of three, and move the dial to match the angle found. For instance, if the target course bearing was 155, heading South East. Your subs heading (I'm just throwing this out) is due North at 0 degree, and you see the target at a relative bearing of 290 degrees. The AoB of the target is 45 degrees Port. You'd set the Attack Data Tool AoB Dial to 4.5 Port and "send" the bearing to the Position Keeper/TDC. How do I know this without running the game? Because I'm using my hand held AoB Calculator to compute the figures into useful information.

Here is the SS I had earlier
The little black dot to the left of the compass rose is the target ship.
You place the compass ahead of the target and read the number that is closest to the target. In this case it's 100 that is the target is heading easterly at a compass heading of 100° 90° would be dead east. Forget the red lines you don't need them.

http://i621.photobucket.com/albums/t...ps6859bb23.png

You would would turn the AoB data entry dial (right side) to the starboard side of the dial (that is the side you will be shooting at) and turn it to where you thing it should be and send to TDC. Look at the left side top dial and see what it reads on the outer ring, the bow of the ship should point to 10 which equals 100°. If it doesn't repeat the process till it points to the 10. Sounds complicated but it's really easy after you do it a few times and your AoB will be dead accurate.



In the two screen shots you posted it looks like the target course would be about 155° or southeast and you are below the target heading in almost the same direction. You put the compass ahead of the target enough so you can read the numbers on the outside of the rose that is closest to the target. Can't see your boat or the target so I'm just guessing but the lower left dial is your boat and it's pointing somewhat east northeast.

What may be confusing you is that the compass is upside down from what a real compass is. The reason for this is if you are drawing a line from one point to another the compass will show the direction the line is going. To understand this take the tool and draw a line from left to right straight across the screen, that line will go from west to east or an easterly heading. That heading will be about 90° and that is the number you will see on the trailing edge of the compass so you have to read the trailing edge of the tool.

My eyes aren't all that good but it looks like to me that you have 335° not 325. It also looks like you are getting the way to set the left dial correct you just seem to be reading the compass wrong.

CapnScurvy post faster than I do.
What he and I are talking about are two different methods of getting data. With my way you don't need any figure for AoB at all just the targets course line or heading. There are no other lines to draw or measure other than the three minute rule line and read it with the compass. It's much simpler, much faster and much more accurate. There is nothing wrong with doing it his way and the way he does it is very good. You can do it either way.
I have nothing but deep respect for CapnScurvy he knows this game inside and out and makes beautiful mods, I use several of them.
We just have two different ways of doing the AoB thing.

Thanks again..

I realized my stupidity..

When I was analyzing the targets information, the bearing was getting me confused.. Because it was far away, the bearing of ship made no sense to me, forgetting that the position keeper would adjust as the ship got closer.. so a bearing of 85 for example, at first made no sense, it showed the ship coming right at me.

Then I realized it was because it was 5000+ yards away.

I think I'm getting it now :)

I had a buzyun about 2k+ yards away and I was going full flank P depth.

I hit both torps dead center! I assume the TDC takes into account my speed?

Yep the TDC will take into account your speed and heading as well if you have to change course for some reason. It tracks both your boat and the target.

Glad to see you're putting it all together, it's a lot simpler than it sounds once you get everything figured out.

"a course of 325 based on the compass from the ruler and when I put 32 on the AOB top right dial, its not even damn close!!"

You're still not understanding angle on the bow.

http://www.subsim.com/radioroom/show...3&postcount=44

If the target is heading due north, his course is 000. You don't enter 0 into the AOB unless YOU are due north OF HIM. AGAIN the Angle On the Bow is the bearing FROM HIM TO YOU. If he's heading north and you are due west of him, you are on his port 90, if you're southeast of him the AOB would be starboard 135. If you're southeast of him and he's heading northwest, AOB would be 18 because you're directly behind him. If he's heading 135 and you bear 135 TRUE from him, then the AOB would be zero because he's heading directly toward you. It doesn't matter which way you're facing, again AOB is the relative (NOT TRUE!) bearing FROM HIM TO YOU.

What that's used for is at the start to figure out which way he's heading, then for the firing solution to set the gyro angle. If his speed is 12 knots and the AOB is port 90, you are on his port beam, so he's moving from right to left and the TDC will apply the full 12 knot lead angle ahead of him to your left, in other words aiming for where he will be when the torpedoes get there. If the AOB is port 45 the TDC won't lead him as much, it will be aiming at a different projected lead angle since the lead is less with less than 90 degrees. If he's heading right toward you or away from you the lead angle is zero, since the bearing won't change during the torpedo run. That's the main reason the AOB is important at the moment of firing, the TDC needs that and the speed to calculate how much to lead the target.

Again simplest method is to plot his course, move to where you're 1000 yards off the track facing toward the track at about 90 degrees (90 degrees TO THE TRACK, don't get compass degrees confused, if his course is 315 then you would be facing 90 degrees to his course, 225 or 045) then set the AOB for 80, wait until he arrives and he IS at 80, and fire away.

Again the best attack starts with a good approach, a sub is not fast or maneuverable underwater, so the best attack starts with doing whatever it takes to get directly in front of the target without being seen and wait for him to come to you. Plot the target track, stay 5 miles away from him until you're ahead of him, then move toward the track keeping out of his detection range. Once you're five miles directly ahead of him near his track you can submerge and do the final positioning, which won't take much speed if you're already close to the track. The target track is the holy grail of any attack.

Magic, we both do it the same way, it's really so simple and a perfect AOB.

Barbarinna is lurking between the Statue of Liberty and the Freedom Tower
 

(Psst. Don't tell anybody, but Nimitz told me that Armistead really only uses auto targeting!)

Well its been some time, and I must say, with total confidence !!

I GOT IT!! :) WOOT!!

I've been doing really well the last few patrols.. I have my system down pretty good.. While yes, I cheat with map contacts on, and checking my firing solution on the attack map, I still have to get all the data.

I spot a merchant and dive to P depth and shut engines down.

I mark the contact VIA hydro's and start timing 3 minutes.. I mark again and get a decent speed down.

I then mark 2 or 3 more times to get a good bearing down.

Then I get into position from the line I made based on his course.

I pop the scope up and enter the speed and bearing.. I check the ship and start adjusting my fish.

Now I start my range.. I will cheat here and there by measuring in the map, as I'm not that good with the stedimeter.

If I miss, I miss, I don't reload (anymore) I take it as a real miss as a real captain would do.. lol what other choice did he have, right? hehehe


But.. When I really realized I had a good sense of manual targeting was just 10 minutes ago.

with only stern fish left (4) I found my contact and went into my routine, backwards.

Only this time when I popped the scope.. Yep.. Major storm, visibility was at best 10 yards..

What to do, what to do.

I set everything like I normally do, only this time I jumped into the sonar station and took bearings and distance manually.

I set them all into the TDC and at about 1200 yards away, I fired 4 spread from left to right 5 degrees.

I waited in real time..

And less than a minute or so.. BOOM... BOOM

two beautiful sounds.. I hit two fish into his side.. Had no clue what kind of ship it was (Buzyon, after I looked) hoping it wasn't a friendly but I made sure my torps were set shallow just incase.

What a feeling!!!

Thanks again all!

woot wtg now you know the feeling
