The predate ARSA's. TRSA's existed when there were only TCA's nad the
FAA hadn't invented ARSA's.


They both predate, and are left-over from, the relevant time periods.

I don't know what above means, but the original statement is still
correct. TRSA's existed long before ARSA's were "invented."

TRSA's are NOT controlled airspace in themselves. Just wannabe radar
service zones.


I don't understand your statement. I've never heard of a TRSA existing in
Class G airspace. All of the ones I've seen have been in Class E airspace,
which certainly is controlled airspace.

But they are not controlled airspace in themselves. It's entirely
analogous to the old airport traffic areas. They were NOT controlled
airspace. A TRSA is just a bunch of lines on the chart that says
"radar services available here."


You are welcome to that opinion. I happen to disagree. It provides a
higher level of service than that offered by most towers in Class D
airspace, and a lower level of service than that offered by radar facilities
in Class C airspace.

It provides different service. A TRSA provides radar service when
class D does not (generally, although there's almost always a class D
tower in the middle of a TRSA). However some class D's provide
radar services without being TRSA's. TRSA's have the side effect of
not necessarily having all the aircraft within it participate, which
makes it inferior to class D and C.


It is a region within Class E airspace where a slightly different type of
radar service is offered from that normally found in Class E airspace. I
would be amazed if there was a TRSA outside of controlled airspace.

It's not always class E.

I certainly don't disagree with your last sentence. That doesn't mean a
TRSA isn't in controlled airspace though.

It's NOT controlled airspace. There are 5 kinds of controlled airspace
in the US: A, B, C, D, and E. They do not overlap. A TRSA may overlap
controlled airspace, but it's jut another concept like a RESTRICTED AREA
etc...
