Not sure anymore where or how I found it. I think I can share it to all that are interested, as the frontpage says " Approved for public release; distribution is unlimited."

I guess I'll have to read that again.

Yes, the image is taken from that document.
Do you understand how to calculate simply the Br?
Just a clarification: the cited formula is fine for a single calculation of the Br, for a Br historian use the cristian's method plotting on navmap.

Now you can use the ekelund range or tables for range predictions, understand if the target range is decreasing or increasing, apply the Spiess graphical method, ecc.
The bearing rate is essential for an efficient TMA.
