Can someone explain how i get the angle w?
Is it possibel to get the tabels for relative bearings and los typs?

The part in bold is important (B/L is much less than 1). It's the small angle approximation, so you don't need "w".
What is this formula in reference to? I just skimmed this thread briefly and didn't see anything.
