Its now about "Performance"
Hey everyone,
First my disclosure statement: I work at FreeFlight Systems in Irving. As stated in my signature block, I was building a 7A, but the kit, Reserve Duty, and work took too much away from the family so I sold the kit and am now looking at completed projects.
The 1201 will interface with the GTX330 and it's variants without a problem and is certified to work with the -330 family as an ADS-B position source, so you are golden
if you want to go that route.
With that said, there was a recent change in the Advisory Circular that changed the requirements of the WAAS GPS from a "certified" WAAS GPS to one that meets the performance standards specified in the TSO. This has created a bit of a sticking point in that how does the buyer
know that a GPS truly meets the performance standards without a TSO. Answer: do you trust the manufacturer? I would say that if a reputable manufacturer of GPS says their GPS WAAS and meets the performance standards or they can point to a true pedigree of performance, then you are most likely good to go.
Now if some fly by night operation kicks out a GPS and declares it meets the standards, I would do some serious research to make sure I'm not sending my money down a black hole.
Ultimately, the FAA views this as they do everything else we install in our EAB aircraft. They have not certified it, they have not inspected it, so they cannot attest to it. Therefore, the responsibility falls back on the aircraft manufacturer/builder.
To your specific problem, I didn't catch the ADS-B system you are trying to hook to other than the Garmin G3X display, so I'm going to assume it's a Garmin 33 family transponder. If this is the case, I would hook your G3X GPS to the -330 transponder and save some cash. Once you are flying, there is a FAA website where you can request a compliance check. They will check the compliance monitor and send you an over detailed, complicated report that will tell you if you comply or not. Until 2020, this is truly a learning tool and no threat offering from the FAA. After 2020....
I hope this helps.
Mike
