Map contacts off

joegrundman · 01-29-11, 06:09 AM

you shouldn't be taking rockin robbins' opinion on the subject of ship's lengths at all seriously.

Map contact updates off is the only way i ever play, and it works fine in sh4. You can do all tracking and targetting via the PK, which works very well without having to plot.

you can use radar for plotting if you have it, stadimeter if you don't. Nisgeis radar mod makes it easier to plot.

But honestly there are lots of ways of getting your data without using map contacts on.

For me map contacts on eliminates the game. I can hit any target at any range every time.

The issue for me isn't convoys, it's fast well escorted TF in RSRD. It's very difficult to get close to use a stad, so I have to have the radar mod. Not much of a problem unless they're going as fast as I.

What is Aob? Just kidding !!

Terrific analysis and explanation. Almost as good as your Solution Solver program, copy of which sits in hallowed space on my desktop computer screen.

I will check on my screen settings and see if that is the problem. I downloaded a freeware program to maximize my ram.

Yep, we all know he is an idiot.

(Last I heard he wsa chasing an American TF at Leyete Gulf trying for his second Essex.) But so am I. Do I believe him or you? Does it make a difference?

[By the way, I have watched the Karamazov videos (the original OLC GUI video tutoiral and the Video Supplement tutorial for OLC Gold) and read the KIUB USER Guide for ATO. Tough stuff, but I sank a moored target at the sub school. I have to keep practicing until I get the technique down, and I see the advantage of a 90 degree Aob attack until I become competent with the AoBF for the more complex manual targeting attacks. You have got me started on the right track, and I appreciate the help.]

Basic Trigonometry is very usefull.

With a bit of practise you will get visual AOB down to +-5Ds (it's not that difficult)
You 'want' to attack at 90Ds so adjust course to AOB+Scope bearing = 90.

Once on course centre scope on target, note your speed and scope bearing.
Adjust your speed so that your target stays on the scope bearing.
From here target speed is just a ratio of your speed and scope bearing.... dam simple

I feel the same way. I don't really understand the need for all the 'no-plot' methods. A good plot not only provides data for your firing solution, but also the highest level of situational awareness. I know there is a role for 'rough and ready' techniques, but they can never be a replacement for plotting, IMO.

I went with map contacts and followed gutted's regimen discussed above. My four shots missed, but not by too much. I was trying to get a 90 degree angle to the target, which was on a coure of 189 degrees. I shot at it from the port side and set my course at 99 degrees, but my shots missed aft of the target by a few boat lengths. I was satisfied that I can master this with a little more work.

What is the formula for getting a 90 degree angle? And is it different if the target is on a course of less that 180 degrees? (e.g. target on a course of 355 degrees. A 90 degree angle from port is 265 degrees and from starboard it is 85 degrees) The the fact that one is shoting from the port side or starboard side makes a difference. I think I have seen this posted before, but I am not sure where.

TorpX · 01-30-11, 02:32 AM

In your example, you got it right. If the target course is X, your course would be X+90 coming from starboard, or X-90 coming coming from port. If the X+- values are < 360 add 360, if >360 subtract 360.

What I meant to say is: If values are < 0, add 360, and if > 360, subtract 360. Sorry for the confusion.

I'm goin' down · 01-30-11, 10:53 AM

add or subtract 360 degrees? That does not seem correct, because if you added 360 to 300 degrees, you end up with 300 degrees. The same result if you subtact 360 degrees (300 degrees - 360 degrees = 300 degrees.)

Nisgeis · 01-30-11, 04:59 PM

Torpx means that if, after adding or subtracting 90, if your result is greater than 360, then subtract 360, but if the result is less than zero (instead of 360 as stated), then add 360.

Course = 300 from port, 300 + 90 = 390. Result is greater than 360, so subtract 360 to give steering course of 30.

Course = 45 from starboad, 45 - 90 = -45, so add 360 to get steering course of 315.

That I can understand!
