I'll have a look at an the Is-Was I downloaded (from subsim forums), and see it involves a relation, or quick-compute way to lay out the data. I dont know if they used a vector system, but it worked for me. I finished that file I mentioned above, it seems to work pretty well, calculating the heading and speed of a target, even when the sub is moving. The math that is going on "in the clockwork" is kind of convoluted, and I'm still trying to trim it down into a simple equation. If someone can do that, they'd have the key to designing the Is-Was, and from there, infinite understanding of its function....So thats what I'm working on!

Also, I had a quick question, can you use an Is-Was when the sub is moving? If so, there most definitely is an underlying relation, and that's pretty much been my holy grail since I bought SH4. Thanks!

My question is: What would be the exact mathematical formula for this? I mean, there must be a mathematical formula to allow calculating the AOB like that without any table and a finger going right-down on it

I'll look at this chart you linked, its very interesting. My german is passable, but I think I get the idea. I assume the U-boat is free to manuever to maintain the 90deg bearing?
Hmm, I'll plug away at it. Thanks for the insight. Thants going to be a few more hours of fun! It doesnt get much more geeky than "fun" math!

Here's a pic of the (extremely junky but funcitonal) program I wrote today to do this math for you. It'll take the place of the stopwatch, basically. If anyone wants to try it, I guess they'll have to PM me with an email address, and I can email it to them. at least until I get my file server back up. I didnt take the time to make an installer for it either, so its just a .rar
