"About formula: (simple trigonometry)
With the law of sines you can calculate the angle § = arcsin( B/L*sin(w)) , w lower angle between B and bearing at time 0.
B/L << 1 therefore § is approximately equal to §* = arctan(B/L) OR §* = arcsin(B/L) [error=<10^-2] ''more easier to calculate''. In the example B is SpeedOwnship/60*2. For obtain L is sufficient bring the cursor on intersection of the bearings when the bearing appear on TMA display."

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

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.

If I understand correctly, the formula should determine a more accurate bearing rate. The formula is taken from an Italian tma manual (see link) I am looking for a decent method to get a better beraing rate, but so far without success. all self-determined beraing rates, for example, with the stopwatch are firstly inaccurate and secondly not suitable for a combat situation. other methods such as MoBo, in my opinion, ****. The general problem is the indication of opponent bearing. in all subsimgames I get, this is given as a whole number and not as a number with decimals.
We need a method with which we could determine the bearing rate relatively quickly after the first bearing. Maybe this formula is suitable? but I am still in the process of understanding them.
Best regards
