Maths hurts my head too much and the link is hard to understand.
Is it something you can use with good sense, but little mathematical knowledge? |
My math is horrible also, but after a while plodding through the Wasserman tutorial and the post I referred to, I was able to figure out how to use the wheels for finding Aob ... so answer to your first question is yes.
I would do up a tutorial with info consolidated from both sources, 'cause I found I had to study both sources at some length, but it really needs pics and I don't know how to post pics to the forum.
But I'll try to describe best I can. Keep in mind that I was only looking for how to get Aob. I gather the wheels can be used for other things, but I haven't the foggiest idea how.
1. I made up the coloured wheel that's in the Wasserman tutorial at the section dealing with finding Aob. A "live" version of that wheel is at
http://www.spidermine.com/SHIII/wheel.swf . I just did screen prints of that wheel and printed them out, they come out pretty nicely, and assembled them as generally described in the post, bearing in mind that this is a one-sided two-disc wheel. I also found that it's much easier to read/understand this wheel (for Aob)than the other one.
2. I made up the black-and-white wheel referred to in the post. That's the wheel originally published by cavalier88, I think. Anyway, it's the three-disc two-sided wheel. The graphics aren't great, but it's workable.
3. The reason I made up both wheels was that the coloured wheel needs to have true bearing to target inputted, as opposed to relative bearing (which is what you get throught scope or UZO). Again, since I have trouble doing the conversion in my head, the black-and-white wheel makes this real easy.
4. Then I just practiced with the example in the Wasserman tutorial how to input target course and true bearing to target onto the coloured wheel to get the Aob.
5. In terms of the details of how I can only say that you have to slog through the two sources. I'll try to figure out how to post pics, and if I do I'll post a summary with pics, but no promises.
6. Finally, just a note about own (Uboat) course. You do need to input this to the b&w wheel to get true bearing to target and there's no discussion in the sources of how to get it. Obviously you can click on the compass and get your course, but since the compass is not accurate in terms of selecting a specific course, I simply hit the = key for heading to view, via the UZO or scope on 0deg, which gives current course without changing it.
Hope that helps a bit.
