[I'm goin' down]

My key point was that it was an good graphical representation. There are several ways to learn: Seeing, reading, and hearing are key techniques to aid thinking. The post involveses visualizing AOB. For someone who is just being introduced to the concept it makes understanding it easier. Nisgeis post is also a good description, but does not contain a grahpical representation. The benefit of graphics is that it displays the various angles that are in play

To understand the importance of AOB applied in an attack scenrio is another issue, and Hitman's tutorial, where aspect ratio is manually calculated and converted to AOB is another ball game, but is useful as a next step because you have the oppurtunity to appreciate its relationship to torpedo attack schematics. Hitman's tutorial culminates in brilliant fashion with a screen shot of Attack Map displaying the results of his tutorial, i.e. the target's Range and projected course pegged to perfection by the TDC with a white "x" and directional line. That screen shoot is follwed by another showing the aftermath of his labors (i.e. the torpedoes' impact). I used his tutorial until I was comfortable with the method, and then moved on to the SCAF mod, which eliminates the need for doing the math he prescribes.
