Another issue is that right now only airlines can really make use of this
stuff anyway, since relatively few people are flying behind v2 GNS-480s.
This is why Jane Garvey said in her AOPA speech that it's important for
pilots to go out and get new equipment that can make use of this. Of course,
I'd like to see her agency help by making it easier to certify and install
such equipment. There's no reason it should cost $15,000 to do so.



Jane Garvey? ;-)

The airlines are NOT making use of WAAS. They have basically told the FAA to
take WAAS and shove it. Almost no airline aircraft have WAAS. In fact, all the
aircraft produced prior to the early 1990s don't even have GPS unless they have
been upgraded (a very expensive upgrade for that type of aircraft certification
process).

The airlines are in the financial fight of their corporate lives. They couldn't
care less about WAAS and LPV.
