How does that work?
I basically follow the method set out in the manual, with my own refinements:
1. ID ship (enter in TDC);
2. get first range reading from stadimeter (enter in TDC);
3. start stopwatch;
4. plug in observed AOB (enter in TDC);
5. plug in trial speed (from sonar station, i.e. "slow", "medium") (enter in TDC);
6. start PK;
7. plot estimated TGT position on NAV map (based on range and bearing in #2 above) (i.e. Mark #1);
8. after 3 minutes as shown on stopwatch, determine new range with stadimeter (re-enter in TDC);
9. plot new estimated TGT position on NAV map (based on range and bearing in #8 above)(i.e Mark #2);
10. draw line from Mark #1 to Mark #2. From this you can reasonably estimate TGT's course and speed;
11. plug in new observed AOB, as determined from course in #10 (re-enter in TDC);
12. plug in calculated speed from #10 (re-enter in TDC);
13. fire torpedoes, based on best range as shown on the Attack Map.
It is a bit cumbersome, but highly accurate. Obviously, I may have to refine the solution between 12 and 13, based on observation of the TGT and how it matches up with the TDC solution.
