The formula is not mentioned in the manual, also the table of the first post is not in the manual. I mentioned the manual (by cristian) just to recommend a precise method for Br calculation.
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.
