Dick,
And Peuce if you want to know about everyone you need both primary and secondary radar- thats what Andersons class C direction covers.
Geez, that would be nice Dick, but REALITY 101 ... CBA.
AND, you are wrong. We've been running Procedural (position report based) Control for eons. We still do it in the GAFA. And we know everyone ... that we are supposed to know.
You don't seem to want to accept (the reality) that procedural control exists.
Jaba .... Frank has a right to his opinion, so I'll just have to weather the inevitable storm. But, in this day and age of more complex and faster aircraft, I don't think we can continue to plead freedom and privacy, at the expense of safety ... at least not in all locations.... and I consider BRM/KTA to be one of those locations.
