Hello Again Bruce, You wrote:
1) "Navworx is non TSO'ed, therefore not legal to use."
This brings to mind the great flap (not yet really resolved) over the use of
non TSO'd altitude encoders. (See CFR 91.217 and the many postings related
thereto.) There are thousands of E-AB aircraft flying around in violation of
91.217 and I don't think that we want to stir that can of worms again.
2) "How does on meet TSO standards without getting approval?"
In fact many of the non TSO'd altitude encoders in E-AB aircraft exceed TSO
performance requirements, but have not been through all the environmental
testing, production process, and paper work needed to get TSO approval.
3) "Navworx is non TSO'ed, therefore not legal to use."
I think that the prudent person buys and installs TSO'd equipment if it is
available. The non prudent person buys what is available that appears to
work, installs it, flys with it, and waits for the FAA to either stop him or
ignore him.
4) "Unless we crack this nut, in 2020 we will be denied the use of most
airspace."
Recall that some time back the FAA planned to put us all into using the MLS
(Microwave Landing System). How is that working out?
'OC' Baker Says: "The best investment we can make is the time and effort to
gather and understand knowledge."
===========================================================
It could have well been a Freudian slip.
Anyway, someone mentioned Navworx on this thread.
According to the data in the regulation (14 CFR §92.225) those aircraft
equipped with Extended Squitter (1090 ES) must meet TSO-C166b, those
equipped with Universal Access Transceivers (UAT) must meet TSO-C154c.
How does on meet TSO standards without getting approval? Navworx is non
TSO'ed, therefore not legal to use.
Unless we crack this nut, in 2020 we will be denied the use of most
airspace.

Yes, I have been through the non TSO'd encoder wars with my RMI
microencoder.
If my Microencoder air data unit exceeds TSO requirements, how does that
help me when I'm standing before a NTSB judge?
