after the last attack, I dove, escaped from the escort, resurfaced and took off again after the remaining "Marus". I wanted to see if I could do a real time radar only surface attack. Again, I took the time to plot course/speed by radar which gave me course: 178 degrees, speed: 8 knots.
so once AOB and speed have been plugged in, use radar to pick up the target (PPI 1), switch to A scope to obtain range (A scope 1), switch to TBT and as long as it is set to the range dial, inputting the range will send the radar range to the TDC (TBT 1).
Notice how the A scope gives the same bearing as the TBT. This is not always the case, but it works well as long as you use the actual visual bearing from the TBT. You will also notice that I do not bother to ID the target.
After that it is just a matter of updating the radar range periodically and comparing the TDC data to the target.
I wound up mishandling the approach and fired from too far away, around 3,500 yds (attack map 1 and 2, TBT 2). Fired a 5 torp spread, one hit (payday 2). Not perfect, but it does show the solution is good.
time to practice some more...
