To merge or not Merge?

[Bellman]

Another good reason to merge SA and TA is, given the more realistic LwAmi 120 deg baffle, if you turn to clear
the SA baffle, and baffle an existing SA sole contact, you will lose your TMA on that contact as the LOBs drop.
The contact remains on Nav but progressively loses accuracy of position relative to truth.
It then takes time to rebuild the TMA unless you turn to re-expose the contact before all LOBs drop.

With a Master, providing you dont baffle both arrays, this loss will not hurt you. Managing turns relative to baffles
requires a little more pre-planning now !
