Yea, you are right.

Thank you for admitting that you are completely unable to provide
evidence of _ANY_ benefits to light GA operators who will be funding
the lion's share of this proposed ADS-B "airspace modernization"
boondoggle.

Lets not modernize our airspace.

Regardless of how much rhetoric is spewed about how NextGen ATC
modernization will reduce airline delays, or provide better safety,
the fact remains, that there is a _finite_ amount of airspace, so the
system is inherently limited. No modernization scheme can change that
fact. NextGen may enable reducing aircraft separation to some extent,
but it is inevitable that a limit will be reached if airline traffic
continues to burgeon.

If you take a
look at the NPRM and the FAA material on Next Gen you will see that it
benefits GA much more than the airlines.

I've looked at it, and I don't see what you are referring to. Perhaps
you'll be good enough to provide an example or two.

I dont know who you fly for,
but the airlines already have many of the Next Gen procedures are in
place.

Can you be a little more specific? To what "procedures" are you
referring?

I dont mean to be sarcastic Larry, but when you fly an RNAV or
RNP procedure do you long for the good old days of vectors and
holding patterns ?

Do you believe that ADS-B and NextGen are necessary for those
procedures? I can recall using RNAV in the late '60s; it is not new.
RNP is a result of more accurate technology. It is funded by those
who use it, not those who don't. Incremental modernization like that
is welcome. But to scrap the world's best ATC system in favor of
large-corporation driven pie-in-the-sky marketing promises is foolish
in my opinion.
