I don't understand. Your prior discussion was in the context of a
terminal controller and center approach control, I thought. That's why I
was trying to clarify that it applied to a towered field using center
approach control.


I believe you're thinking of terminal controllers as strictly tower
controllers. Terminal controllers are those working in control towers and
approach control facilities.


That's how I normally think of terminal controllers. But I thought you had
excluded the approach control facilities when you used the context of fields
using center approach control.

Do you call center controllers "terminal controllers" when they are working
approach control? That could be what I missed.


What exactly were you asking when you wrote, "So this becomes an issue
only at a towered field using center approach control services?" I took
it to mean the auto-acquire of tracks by ARTCCs. Tracks auto-acquire
wherever they happen to be if they're observed by center secondary radar
when beginning their flight.


I no longer think I understand anything about this discussion of under what
circumstances a controller can change a flight plan. I need to find a new
starting point, or just abandon it. It seems to be an obscure issue for
pilots, I was just curious when it came up.

Thanks.
