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

The R in a circle symbol indicates ASR is on the field, it's used
at airports when no other indication of the presence of radar exists, such
as Class B or C airspace or a TRSA.


Which raises another question. What is in a TRSA that isn't anywhere else? I
know a TRSA is sort of a stillborn class C, and (from the name) you can get
"radar services".

So, which ones?

Is it the case that you can get the same (radar) services in a TRSA that you
can get in class B or C airspace, or the airports with the circle R (that isn't
the one meaning "restricted/private airport"), and it's just that because of
traffic volume or the thought it would become a class C that the airspace was
carved into sectors?

And what services can you not get outside the sectors that you can get inside
them?

VFR aircraft are separated from IFR and other VFR aircraft in a TRSA, but
participation is voluntary. VFR aircraft are separated only from IFR
aircraft in Class C airspace, but participation is mandatory. All aircraft
are sequenced to the primary airport in Class C airspace, not so in a TRSA.

One thing that VFR's should note, that while participation is voluntary in the TRSA,
many TRSA towers get a bit testy if you don't go in through the TRSA-approach
control.

Sure, because now they've gotta find you and sequence you. If all VFR
arrivals use TRSA services, which require separation between all aircraft,
sequencing is automatic.

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 found only one on the Chicago Sectional, at Waterloo (ALO).

ALO does not have a TRSA.

There are five on the New York sectional: Elmira NY, Binghamton NY, Utica
NY, Wilkes-Barre PA, and Harrisburg PA.

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

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.
