R in a Circle (Airport Surveillance Radar) on VFR charts

Please review the subject of this thread, which is the use of an "R" in a
circle on Sectional Charts to denote the presence of Airport Surveillance
Radar at specific airports.

It appears Mr. Reid introduced TRSA's into the mix, a point I failed to
note. And it appears that a TRSA is not the same thing as Airport
Surveillance Radar.

So, my statement, in response to the original subject, that the only Airport
Surveillance Radar on the Chicago Sectional is at Waterloo (ALO) is correct,
assuming that I found all that were on the chart.

And your statement, in response to the changed subject: "I know of TRSAs at
Rockford, Illinois, and Muskegon and Kalamazoo, Michigan", is also correct.

Idle question: how common are TRSAs? I can find only one in all of
California, but that doesn't say much about other parts of the US.


I know of TRSAs at Rockford, Illinois, and Muskegon and Kalamazoo,
Michigan.
