TRSA and /X

No. Why do you ask?


I ask because your question:

Do you know of a TRSA which does not have
Class D airspace in the middle?

in response to Ron's parenthetical comment

...although there's almost always a class D
tower in the middle of a TRSA

implies that
1: there isn't any TRSA without a D, and more to the point
2: Ron should know this, Stephen does, nyah nyah nyah.

You phrase it as a snipe, which comes off as if you are being smug and
superior. Even if you were asking a neutral question because you were
curious, your posting history makes it easy to interpret as a snipe, and
snipes get tiresome, especially when the fine point they are based on
is incorrect or misleading.

Ron's remark ("almost always") remains true even if there are =no= cases
of Dless TRSAs. It implies that there =might= be, but not that there
=are=. So as a snipe at Ron, it misses.

But now I am curious as to your implication that they are impossible.
(Were they actually impossible, Ron's "almost" would be unnecessary,
though not incorrect). Your snipe implies that you know so and want to
belittle him who doesn't, by not telling and instead asking
rhetorically. (If you didn't know, a more pleasant neutral question
would definately be in order.)

Given the earlier discussion about the independence between towers and
class D airspace, I'm curious as to whether these things are in fact
independent, or (as you appeared to imply) not.

And yes, I phrased it as a snipe myself. Sauce for the goose and all.

TRSAs can and do exist in Class G airspace.

Which TRSAs exist in Class G airspace?

Which TRSAs exist in Class G airspace?

RME (Griffis NY) is an airport in Class G airspace (ceiling 700ft). An
overlying TRSA goes down to the surface at this airport. (Another
nearby airport is in Class D airspace, which also has the TRSA going
down to the surface).

Well, this is certainly very interesting! I have a 1987 New York sectional,
Griffiss AFB was still open then. At that time Griffiss had a full-time
Control Zone and a control tower, what we now call Class D airspace. What's
really interesting is that there've been no changes at all in the
configuration of the TRSA. None! The boundaries and altitudes of the
various areas are all the same. Notice the semicircle cutout ESE of UCA
where the floor of the TRSA is at 2000'? That was to accommodate Riverside
Airport. The airport is gone but the cutout remains. There's a small,
almost rectangular area northeast of RME where the floor of the TRSA is also
2000'. That was part of the Griffiss Control Zone, so the floor of the TRSA
was about 1500' above the floor of controlled airspace in that area.

I have to wonder if it's an oversight. When the TRSA was established
Griffiss had a SAC bomb wing and a TAC interceptor squadron, one assumes the
TRSA was configured to accommodate them. Their departure would seem to
warrant some changes in the configuration. Having a TRSA extend to the
surface beneath a Class E 700 area serves no useful purpose. ATC cannot
assign an altitude to any aircraft and can only vector VFR aircraft and only
upon pilot request.
