It is precisely as bad as it sounds. I paid for dual receivers and I paid for 2020 compliance. Anybody want an EXP?

Any speculation on how the AD may affect the 600EXP? All the comments have been very quite about what may happen with the EXP . Being a non TSOd unit for LSA and Exp, it will be interesting to see what the fate of this unit may be. AOPA comments for the AD were fairly direct in how the FAA could and could not address the non certified experimental device Anyone have any inside info?

See my other post# 2

Dallas Avionics believes there will be no action on the EXP boxes.
That is of the opinion of Scott Edwards.

Time will tell. Some say is only a few weeks away. I would think it will be settled before Oshkosh. I don't think Navworx will want to show up there without this issue being resolved.

Got my unit back from repair yesterday - re-installed today.
Looks like it is functioning properly with the exception of display port 2 - which is a known software issue.

I guess we'll know more as we hear from others...and when the AD Actually comes out!

Lol...guess it depends on your outlook. My ADS600-B has already cost me the $500 rebate which I will not be getting.

I can't use the position output from my 430W as I can't get to the wiring bundle :-(

Anyone know if the position output from the GRT 2020 external GPS module can be used as an input to the ADS600-B?

Keeping my fingers crossed...

My interpretation is that the software update will guarantee that the unit will work until 2020, at which time you must use a certified GPS source.

You then have two options, use an external certified GPS source (i.e. GNS430, GTN650, etc.) or purchase the GPS upgrade from Navworx.

If the output from the GRT box is ADSB+ which the GRT website says the GRT SafeFly is - you should be good to go!

Just remember, The FAA has already changed the rules once - which got us to where we currently are!

Nowhere does GRT say the output format is ADSB+. In fact it does not offer that option, which I believe is a proprietary Garmin code. The new GRT box outputs NMEA 0183 at 4.8k and 9.6k; and NexNav format at 38.4k ("NN33"). The NN33 can be used by the Trig TT22 and 31 transponders.
In addition, several manufacturers have told me that the FAA wants a statement from the manufacturer that their GPS box meets the TSO specs when paired with specific transmitters. GRT has such a statement in the manual for Trig transponders (TT21, 22, 31) and 'soon' for Sandia; plus the just announced Echo UAT. There is no statement for the NavWorx products.

You are correct - Here's what is on their website...:

The GRT Safe-Fly is a 2020 ADS-B compliant GPS, allowing it to be used as the navigation source for your compatible ADS-B output. This full compliance with FAR 91.227 allows your ADS-B output to trigger the return of traffic data. This demanding standard requires a GPS that is reliable to better than one undetected failure per million hours, making it a natural as your navigation source for your GRT EFIS.

For what it's worth (I know, its worth very little), I am of the same opinion as Scott.

After reading the docket comments on the NPRM, I think the FAA will quietly step back from doing anything about the EXP. (With the exception, of course, of forcing it out of new production.)

I believe this mainly because the exact same GPS that NavWorx used in that unit is also used in a whole series of name-brand products within the Experimental community. And the FAA has no stated intention of issuing a rule against any of those products.

Which again begs the question of why any of this heartburn was necessary in the first place, but I digress...

If the FAA leaves the EXP units out of the AD, they are accepting Bill's premise of functionality over certification (and the initial reason for acceptance of the 012 and 013 units) - for the Experimental crowd!
