How to work these

1. Print a maneuvering board. The plotting solution lives on paper, not on screen. Plot sheet 1 or plot sheet 2 — either works.
2. Open the exercise. Each problem is a single PPI snapshot showing your-ship-at-center plus 3+ plotted positions of one or more contacts at known times.
3. Transfer the contacts to your maneuvering board. Each plotted point is a (bearing, range) pair — read off the PPI and re-plot on the board.
4. Build the vector triangle. Lay off your own true vector er in reverse from M₁; the relative vector rm along the RML; close to find em. See Plotting for the procedure.
5. Answer the typical questions: CPA, TCPA, target's true course/speed, course-to-pass at a desired CPA. See Collision Avoidance for the constructions.
6. Check the solution. Where a solution sheet exists (No.5, No.8, No.11), tap "Show solution" on the exercise page.

These were originally distributed with the Starpath Radar Trainer software (RT3). The solution sheets work standalone — you can use them as reference even if you don't have the original RT3 application. Note that exercises No.4 and No.10 don't have published solution sheets; trust your construction or compare with a peer.
