Indeed. You won't get Mode S on the UAT link. Two completely different
schemes.

I'm not really sure what you mean by "get Mode S".


As far as providing other services (ok, "features" , I believe one
of the things they are looking at, is taking ADS-B In to drive a TCAS
display (ADS-B is *not* currently certified for collision avoidance).

You can count on that as TCAS currently has accuracy limitations which is
why the range is quite limited, but this is more of a recent development.
As far as what I mean by "features", I'm talking about everything that ModeS
was originally intended to be capable of doing. You have to remember that
the technology is over 30 years old now. Much of what was originally
conceived will never be implemented.

AIUI, most of the rest of the world (those bits that are planning
ADS-B) are looking to do it that way.

1090 if you're one of the bigger operators, or perhaps smaller folks
with deep pockets. UAT is lower cost.

1090 only gives you TIS. UAT adds FIS (Weather, NOTAMs).

1090 is capable of considerably more than TIS. Some of that capability has
already been realized, but it remains to be seen how much more will. The
airlines already get the products you mentioned through ACARS.

What I meant was the UAT datalink is not equipped to receive (or
transmit) Mode S. But I misread what you wrote, so I guess it doesn't
matter.

Are those products received over 1090?

1090 ES doesn't have the bandwidth necessary to do much in the way of large
data transfers, however as far as the big airplanes go, there's really not
much need. ACARS gives them far more and would not go away even if it were
possible to put those products on 1090 ES.

No doubt. I was mainly commenting on what UAT provides, not about
whether an existing 1090 user could receive those equivalent products
with a 3rd box.

What does ACARS run on? Satellite data, or shortwave radio?

You can read all about it on Wiki:
http://en.wikipedia.org/wiki/ACARS

I don't have that much knowledge about ACARS. All I know is ARINC maintains
that service and ACARS equipped aircraft can receive clearance delivery
service on it at major airports in the US without ever talking to ATC. I've
heard Jet-A burners say they can receive METARs, NOTAMs, and digital ATIS
information on it. I would assume airline dispatchers can send and/or
receive short text messages on it with the aircrews, but I have no idea if
this is the case.
