So, you're going to have a situation where you either have a layer or you don't in this game.
If the line on the SSP goes down one way and then changes direction another way with a horizontal line at that point, you have a layer and its depth is displayed. If it is a straight line with no change in direction that ends abruptly, there is no layer.
It is very much possible to determine the range of a contact passively. And no you don't need TMA if you have all the information. The TMA is to help you get a solution when you don't have all of the information, surface or sub-surface contacts.
1) You can use the WAA RNG on the broadband of the Seawolf to instantly determine a contact's range passively.
2) TMA is how you do it otherwise. In math, you need one equation to solve for one unknown. If you know three things--in this case it would be course, speed, and bearing--then the only unknown is range. The one equation you need to solve that is the TMA plot. If you know three things, only one solution will fit in the TMA plot. You can also "bypass" this one unknown thing to some degree by making several different course changes. This also locks the TMA down to a very few number of solutions. However, that's getting more advanced. The manual also has more info on that, too.

Thats a few awesome hints! Thank you i understand SSP now way better

How? do i make 1 track for every array (2) and then merge them in TMA?
