Approach Planning
 

Here’s something I put together. These charts allow you to range using the target course line, using the momentary range table.

Then the tables below that have own speed as the title allow you to determine the most optimal angle on bow of the target at which to turn 90° to approach. The numbers in the body of those tables are the closest point of approach that you can get at that particular speed. This allows you to determine exactly the angle on bow to turn at, and own speed needed, to put yourself at perfect range at shot.
