Lar, your first post said that air carriers are going to be exempt and
now you say they will benefit ?

The airliners are already equipped with Mode S transponders and
certified GPS receivers. The cost of installation of an ADS-B box is
a VERY SMALL percentage of the value of the aircraft, unlike light GA
where the ADS-B installation might comprise 50% of the value of the
aircraft.

Actually, I would hope the air carriers benefit because if they benefit,
we all benefit. *

I'm still waiting for you to list the benefits to GA aircraft owners
that the FAA's ADS-B NPRM will provide. If you are unable to list
them, I'll have to conclude that you agree that there are none.
