Terminal TMA?

when you have already launching your fishes, the most important LOB will be the last one only.
So, to follow the target path :

1) stick at the DEMON screen to look at the target speed change

2) each time a new LOB appear, it become the one who need to be the best aligned.

a) If you have merged the contact, it's really easy => just put the last tick mark of the ruler on the last cross beetween white and purple LOB, THEN, after only, align the 2nd tick mark with the 2nd LOB cross.
Enter and lock the speed you had the time the last LOBs were falling.
here you have excellent anticipation of the target path.
You will also see easily if the target is turning or just staying at the same course.

b) if you have only one LOB, its a bit more technical :
You need 6 LOB with a single tracker to make a good TMA, when you needed only 3 LOB with a merged track
here, you will lock the RANGE and NEW speed before to align the last tick mark of the Ruler on the last LOB. You must do this to avoid to lost the orginal target path, because it's really easy to do this when you have only 1 sensor to work with on a maneuvering target.
But if you do so, you will have a very nice solution, more than enought to guide you fishes to the target, and more than enought to see the real new path of the target, even if it just turn 180Â° or move away from you.
this is for the first LOB falling after your your torpedo launch
for next ones, you need to compute a bit yourself the distance =>
you know traget is going now at 25 knts away from you, so unlock the range and add 1000 yards (25 knts for 2 minutes ~1000 yards) more then relock the distance, confirm the speed and align the last tick mark with the last LOB.
Whatever the target maneuver and speed change, you can follow it at all time like this.

The TMA on SC is easier than in DW because you don't have things like corrupted LOB or beam wander effect.
whatever you do as maneuver, you always have good LOBs
If you maneuver in DW during data record, this will corrupt the new LOB, making the TMA on DW more dificult, but more realistic.
