I can't say I'm surprised. I've flown some TIS equipped aircraft
and I think it's one of the best traffic avoidance technologies I've
seen since TCAS. It figures that the FAA would choose to implement
"cost savings" by deleting something that actually works and works
well.

ADS-B makes TIS obsolete. No reason for the FAA to invest in two
different technologies. ADS-B holds a better future.

The FAA should be deploying ADS-B more agressively, so that people don't
continue to waste there money on transponders that are going to be obsolete
in 10 years.

The mode S transponders still have things to recommend them other than
TIS, though TIS was a major driving factor in my selecting one.

Such as?

Is it worth the doubling of the price for a transponder?

The problem is that TIS is much easier and less expensive to put in an
aircraft. I can spend about 6 AMUs and have TIS along with a really nice
X-ponder, GPS, XM WX and all the other goodies provided by a Garmin 496.
There isn't room in my aircraft for any current ADS-B ability.

From my reading, it appears that ADS-B is itself three different
technologies (ie. there are three different models of transceivers). If
so, the claimed peer-peer capability of ADS-B will be limited.

Isn't the FAA committed to ADS-B? If so, isn't TIS-B likely to
replace TIS, or is TIS-B backwards compatible with TIS?
