TIS (traffic information service)

If TIS was only useful
for a year or two I'd consider it worthwhile. The Feds have indicated
that deployment of ADS-B in our area is a decade away.

I routinely fly across NY state and all the class C airports from western
to central and onto eastern NY offer TIS. Two years ago I installed the
Garmin GTX330 transponder that displays TIS traffic on an MX20 and GNS430.
It is definitely worthwhile in these areas.

Here's a good TIS map that includes the ones scheduled to be shut down.

Yep, a lot of my flying is in that big blue blob over the northeast US so
TIS serves my well.

But the question facing me (and my fellow partners): would you buy TIS
*today* given the FAA's emphasis on ADS-B and TIS-B?

Note that they just brought online more of PA:

The question isn't whether you should buy TIS. It's whether you should
buy a Mode-S transponder, because that's the primary difference between
the 327 and 330. TIS is just a perk of moving to Mode-S, and it was
specifically designed that way to encourage pilots to move to Mode-S
when it became clear they would not otherwise willingly adopt the new,
more costly, technology.

The FAA is continuing to invest in Mode-S radars (the ASR-11 is
replacing the ASR 7, 8, and 9 units that currently support TIS), so an
investment in the airborne component is still a wise move and will be
for MANY years.

Oh, and don't believe the hype out of Blakley's mouth for a second.
ADS-B is not being deployed so they can "decommission radar". That will
not happen in our lifetime due to security concerns. I fear that the
*real* reason the FAA is pushing ADS-B is for billing purposes. With
the kind of reliable and accurate position data facilitiated by ADS-B,
they could charge us by the mile.

I'm happy to hear, that someone thought about that. It would be a
simple matter to spoof the positional data I would think.

I would guess the reason has as much to do with compatibility with the
ATC system products of Boeing and LockMart.

Not if we don't let Congress out of oversight responsibilities for FAA
funding.

Aside from TIS, what is the benefit (either to the pilot or ATC) of mode S?

11's are not replacing 9's. They are a stripped down 9.

The FAA is installing new radars but they leave out the software that
supports TIS. That's what happened to us. We had a 7 with mode S and
TIS was operastional. We upgraded the radar to an 11 but they do not
install TIS stuff in the radar.

To ATC? Nuthin' I wouldn't know if you had one.

Mode S has several advantages. ATC interrogation pulses can be directed to
a specific aircraft or all Mode S aircraft. Replies to the interrogation
can contain specific information (altitude, aircraft ID and airframe type).
Interrogation to all Mode S aircraft could illicit a reply from my Garmin
GTX 330 that contians my tail # and type and altitude. I don't know if all
of this is currently functional in any or all of the Mode S facilities or
not but this was the original intent.

http://rfdesign.com/military_defense...e_technology/I think that it's a great thought that will give way to ADS-B. TIS is agreat tool also that will probably pass by the wayside. But my 2 or 3 tripsper month into the Dallas Class B are made easier with TIS. FSM where I'mbased had TIS for the first year after I installed the Garmin but theyupgraded the radar (to ASR 11, I believe) and are not going to turn TIS onfor whatever reason.MarkN28409WC5I"Andrew Gideon" wrote in messagenewsan.2006.08.30.23.39.09.697508@gideon. org...
