Subcourse (heading) + targetbearing = X. If X > 360, substract 360 = bearing target. I that correct?...im not good at math  |
Yes, correct. There are some handheld tools (or recreated in a program) created over the years that make it alot easier. But if you don't feel like DIY work then number-crunching is a must.
Some handheld tools:

Some of the download links mentioned on the pages may be dead. It's been a while. Anyway the links to Rapidshare need a bit of patience. I got a warning that their servers are overburdened. If you can't get anything I'll try and upload them to my filefront page, if it isn't allready there.
These things make calculation very 'simple'.(multiplication/division on one side ONLY, adding/subtracting angles on the other side ONLY) You just need to know in which direction to spin those wheels and in what order. Magic, I tell you!
