If you get an answer of, say, AOB 70, but the target is moving *AWAY* from you, then you know the AOB is past 90 degrees. So, you have to subtract 70 from 180, giving an AOB of 120.

If it helps you to visualize it, an Angle On Bow of 120 degrees is equivalent to an Angle On Stern of 70 degrees.

Make that "AOB of 110". But you're forgiven.
