Your statement is out of date since the implementation of WAAS and boxes
certified under TSO146a.

"...installation of WAAS avionics does not require the aircraft to have
other equipment appropriate to the route to be flown."

It has to have the additional WAAS avionics goodies. Simple GPS needs the backup.

Blueskies,

It is interesting that GPS only IFR is not approved...


No, it's logical in terms of risk-minimization. Avoidong glass panels
isn't.

Call me old fashioned, but you won't find me behind a glass panel or
flying a "plastic" airplane. Just something about flying a bird where all
the instruments don't rely on one type of system and the wings won't ever
delaminate no matter what color I paint them...

OK You're old fashioned. Your reference to "a "plastic" airplane" suggests
that you're uneducated as well. As for "glass panel" avionics, the future

Probably half of us who fly or are building them call them "plastic".
It just has a nice ring. :-))

will leave you behind. I assume you never fly in newer commercial
airliners.

Nothing wrong with composites, IMO, but multi function glass panels are not
yet my cup of tea.

Why?

Too many eggs in one basket. If any of those things go bad, you've gotta
pull out the whole thing and send it back to the factory. Depending on the
repair backlog, there is no telling how long the airplane will be grounded.

With steam gauges, there are quite a few in my panel that I could legally
fly without. Also, I could get a replacement for any steam gauge in my
panel 24 hours, which means I'm not going to be grounded for days or weeks
waiting on replacement parts.

Completely untrue. If any of those things go wrong, you pull out the
malfunctioning module. To the contrary, you fly with all your eggs in one
basket now. I would not be surprised that you are flying a plane with only
one vacuum pump, no backup electrical system, and only one pitot static
system. Most glass cockpit planes have two vacuum pumps, backup electrical,
and backup static ports.

With steam gauges, there are quite a few in my panel that I could legally
fly without. Also, I could get a replacement for any steam gauge in my
panel 24 hours, which means I'm not going to be grounded for days or weeks
waiting on replacement parts.

It would be interesting to know what gauges you think you can legally fly
without.

All the instruments do not rely on one type of system in a glass panel.
Pilots should know better by now. Knowledge of how glass cockpits work is
now a requirement for both the knowledge and practical tests -- IOW, if you
still think that they work on one type of system then the FAA thinks you
should not be a pilot.

This is an interesting statement contained in the NTSB prliminary
accident report of the SR22 that crashed in Florida this past January.

"According to maintenance records, the PFD had been replaced on June 4,
2004, at 12.2 hours, on September 14, 2004, at 55.2 hours, and on
December 20, 2004, at 80.6 hours."

It is about as interesting as if the NTSB report noted that the oil had been
changed.

Not after you read the full narrative and learn about the multiple
altitude and heading deviations in a short period of time.

So post it. It had better be interesting.
