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

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).

Isn't the USA going to implement ADS-B using the 1090MHz Extended
Squitter - such as can be done with a GTX330?

The capstone project in Alaska implemented it with UATs and I'm pretty sure
that's the way it's currently being implemented on the east coast working
its way west. *

As far as extended squitter goes, I know at one time that was
the plan for the airlines because they had already made a large capital
investment in it. *

Pretty much. Have to be compatible with and continue to support that
big installed base if you want a prayer of it being accepted/adopted.

I'm not really sure what progress has been made on that
front.



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).
