TRSA and /X

The explanation is in the AIM reference.

Something I've always wondered... why do TRSAs even exist? Seems like a
dangerous proposition to choose some airports as having the concept of
a voluntary controlled airspace? Why not a Class C (their closest
cousin as far as I can tell)?

Is VFR participation by a non transponder equipped aircraft
encouraged/permitted in a TRSA?

Thanks.

Yea.. but the simplified explanation is:

A TRSA is an approach control type radar service into an area that is
not serving a Class C or Class B field. As others have said, it is
non-regulatory. The airspace within a TRSA is either Class D or Class E.
I have yet to see a TRSA encompass class G airspace (other than the
presumption that ground to 700 feet is included) but from a logical
standpoint it seems counterintuitive to provide "control" to traffic in
"uncontrolled" airspace.

The difference between center and approach class radars is significant:
closer in vectors to final, faster update rates, etc.

While participation by VFR's within TRSA's are voluntary, my "local"
TRSA at Beaumont, TX (KBPT) advises aircraft inbound to KBPT to contact
approach first, who will then hand you off to the tower... so by
practice, going into the primary airport at THAT TRSA is defacto a
mandatory participation

The only place TRSAs reach the surface is within the core Class D surface
area. The outer boundary of a TRSA does not extend below the base altitude
of Class E airspace.

Please take a look at KRME on a sectional chart and compare what you see
to your statement above. The TRSA is charted as descending to the
surface in the immediate vicinity of KRME, which is Class G airspace
below 700'. A nearby airport has Class D airspace, however RME is not
in (or under) the class D airspace.

I don't have a current New York sectional, but I did look at KRME on
Aeroplanner.com and I also examined an old sectional from when Griffiss AFB
was still open. Please see my comments about that in another message in
this thread. Please also compare my statement above to what the AIM has to
say about TRSAs.
