Alright folks, more updates to this file! See Bearing Change file in my sig, and simply click File - Download As - Excel to save a copy for yourself.
I have added the following:
1. A "how to use" tab detailing use from initial sighting to firing, step by step.
2. A Range Calculation section to tab 1 to compute range based on AOB, speed, bearing, and own speed. Purpose is to establish a plot by which to check initial estimates during overtaking.
3. An "attack disk" to tab 2 to allow the normal functionality of a hands-on one (derive AOB from course, and course from AOB, with the bonus of a lead angle generator for those diehards not wanting to use the TDC).
Those are the main changes, but please read through the How to Use tab for how all the pieces fit together. I have been spending time solo recently testing this out and it works.
