- The Primaries [capital city airports] will have PPRIMARY radar [not TXPDR dependent, energy skin return] so ATC will see raw targets. They will also have Mode S and MLat-ADS-B [for PRM and Ground surveillance] for TXPDR returns.
- Outside of the Capitals it will be MSSR or ADS-B or WAMLat which are all dependent on a TXPDR [A/C and/or ES] output to be seen by ATC and ACAS, the later also where ATC surveillance does not exist.
Mr Arouet
ADS-B IN was never designed to be a replacement for ACAS, as it does not provide RA's. ACAS on the other hand is greatly enhanced when it can [change 7 and later] receive the additional information such ES data [position, azimuth, trajectory, etc]
Ironic isn't it that GA in the US will now pay twice for the folly of their unique ADS-B variant.
LeadSled [a.k.a Mr UAT] is very quiet
