Two TA = No bearing ambiguity

Yeah, with ARCI it'snow possible to run TB-16/23 and TB-29 thinline processing concurrently. It may or may not be used for resolving ambiguity, though I will say that the old-fashioned method has always worked just fine.

One gripe of mine in the game has always been the TA screens on subs. Our towed array broadband looks almost exactly what DW put in place for the FFG. This dual-sided nonsense is annoying, and clutters the screen in high contact density scenarios.
