OK Galaxy,
i gave it a whirl.
Personally i use another tool for aob-target course conversion, specifically the submarine attack course finder and the kriegsmarine equivalent

But, I have a couple of suggestions for improving the versatility of your tool.
It's not the case that everyone wants to only convert from target course to AOB. For many of us, it is more important to be able to convert from AOB to target course, so if possible could you make it so that it could solve either problem?
The same could be true of speed too.
E.g for given speed, how far in, say 9 hours 30 mins.
This could help plan long range intercepts
Other than that, id just like to say, great way to make your presence known galaxy
Welcome
edit:
one last thing, you abbreviate Starboard as STRN, which is not a well-known abbreviation.
May i recommend Stbd?
