TIS and What could have been

Unnerveing thing happen to me today.
I have TIS displayed on the Garmin 430.
I was 15 or 20 miles north of Moraine (I73) in southern Ohio and
talking to Dayton Controller under Flight Following.
I'm at 4500 ft and landing at Moraine. I request (I'm in his air
space) the controller that I would like to start my decent and he says
cleared to decend. Shortly, the display squacks and says "traffic" and
I see a traffic indicated at 500 ft below. I tell controller that I
have traffic on my display 500 ft below and he says "Yes, it is a 172
going into Moraine also."

So now we have a low wing (my Archer) above a high wing (172) and I
have been cleared to decend. I tell the controller that I am stopping
my decent and turning left 30 deg (and speeding up). He did not
respond. The 430 display over the next minute shows seperation and I
turn back to course and see the 172. I continue to keep my speed
greater that his and we both land without further problem.

I think TIS may have saved my ( and others) life today and the FAA is
decomissioning the sites with the explination that ADS-B is going to be
better when they get it implemented in the next few years and an an
inexpensive plane electronic becomes available.

God, I wish I knew how to stop this decomissioning of TIS before ADS-B
is widely available. My life (and maybe yours) may depend on it.

According to the most recent AOPA magazine, TIS in this form will be a
distant memory as of 2012, when the last of the radar sites is upgraded to
the latest technology.

I guess I'll toss my Garmin Mode-S transponder into the same heap of
garbage as my WSI weather receiver since they both represent good
technology that became obsolete.

More and more we buy devices, not for ourselves, but for the benefit of
other companies who support (or don't support) them.

You were never restricted from descending in the first place.

That's correct. TIS was obsolete before it was even commissioned.

Not to mention impractical.

Why so?
I find it very useful and practical when it is available.

Boy, the installer for the mode S a year and a half ago didn't mention
that it was either impractical or obsolete!

It is impractical from a total systems perspective. It's not unlike TLS
and ILS.

I am sure it is a nice-to-have when you're in the limited service areas.
TCAS, on the other hand, works everywhere independently of the FAA's ATC
system.

It's a niche solution and competes for resources.

Had you been assigned any altitude restriction prior to your descent
request? If not, then you were free to descend at any time. But it seems
odd that you weren't assigned an altitude restriction as you'd be pretty
much right over DAY.

Yes, I had been told to start decent to 3000. I was in DAYs class C
airspace. I know that in the sever clear of that day, I have the
obligation for seperation, but that doesnot change the controller
allowing decent and my TIS helping to correct the siruation.

Was that before or after your request to start descent?

What was the situation? Where was the other aircraft in relation to your
own?
