What 4 word term is used to describe the method used to determine if a
vessel is on collision course with yours?

Hint: Outfielders use this method to catch fly balls.

Steady bearing decreasing range.

That's about as basic as you can get.

Correct, though I was thinking of CBDR. Constant bearing decreasing range.

I kind of like "Constant Bearing, Closing Range", a bit more alliterative.

I've never seen an Outfielder using a hand bearing compass while running
down a fly....

Hold the glove up, site the ball relative to the glove. Move position so the
ball stays in same relative location to glove. The ball keeps a constant
bearing relative to the eye-glove and has decreasing range.
