Sam,

Not in the U.S.


Source? A source that shows a Garmin GTX330 does not transmit flight ID
data in the US would suffice.


If a tree falls in the woods, but nobody is there to hear it, does it
make a sound?

Good way to put it.

Plus, in the high end gear, the Mode S message data can be implemented in
stages.

Some of the ModeS features will never be implemented and the ModeS Extended
Squitter will mainly be used by the airlines. For GA, I don't think you're
going to see much in the way of new ModeS features as the ADS-B UATs will be
the preferred new technology path for data link.
