Hi,
I am a noob to submarine sims as a whole (sh4 is my first). I am however versed at trig, but wasn't understanding "where" the AoB was coming from. I kept thinking that the bow of your sub was taken into account and that somehow intersected your targets heading to create the angle. It seems that, in these forums, that the AoB comes up a lot and even the video tutorials don't explain where the angle really comes from. So I spent a few minutes in the Nav map and came up with a visual representation of "what" the AoB really is. I turned on autotargeting to see what the angle the computer set for the target, then used the drawing tools to map it out.
Many of you probably know this, but for those who don't and may want to plot it here are the images.
1) With the compass and protractor you can see that if you draw your normal target course line and a line from the center of your sub to the center of your target, the intersecting angles are about 22 degrees.
2) This image is what the auto-targeting computed.
So, incase there are those that are confused about where this angle comes from, you now have a graphical representation of AoB.
