Dynon Skyview ADSB

[b432291]

I believe the freeflight solution above IS 91.227 compliant. I thought (Dynon support can correct me) the only thing lacking with skyview was a 91.227 position source. If they had that then a skyview with their (trig) transponder and the ads-b in module would give you ads-b in and out.
Could Dynon support please clarify?

The Dynon Transponder is fully TSO'd as an ADS-B OUT device and thus is 91.227 compliant.

You also need a 91.227 compliant position source attached to fly in airspaces defined in 91.225 after 2020. The Dynon GPS is not 91.227 compliant, but the transponder is.

Some devices like the freeflight are both GPS position sources and ADS-B out devices all in one, and both elements are 91.227 compliant.

The FAA is in the middle of draft guidance on what an experimental really needs for a position source, and what "compliant" means, so it's an interesting time for all of this.

Dynonsupport,

I apologize for being redundant, but if I want ADS-B out can I:

A) Using the Skyview/Trig combination, I would need to buy/install a Garmin 91.227 compliant GPS which would wire to the Trig?

B) Use the current GPS position source that the skyview has (until 2020), is ATC accepting this today?

C) Will Dynon be offering (I'm not asking WHEN, just IF) a replacement GPS position source for the Skyview system that is 91.227 compliant?

I hate to force a answer, but Dynon Customers need to know Dynon's long-term intentions.

Ted,

A) You can buy a 91.227 compliant GPS today and wire it to the SkyView transponder and be fully 2020 legal. This can be an IFR navigator (Garmin or Avidyne, Bendix-King likely in the near future).

You can also buy a stand-alone GPS from Freeflight or Trig if you aren't looking for IFR GPS navigators.

B) Remember, you only need a 91.227 GPS to fly after 2020, and then only in 91.225 airspace. Dynon's non-compliant GPS works fine today, and wakes up the ground stations to give you traffic. No, ATC doesn't see your ADS-B position with this solution, but until 2020 that is not an issue. In the end, the issue isn't if ATC can see your ADS-B, it's if your plane is legal against FAR 91.227 and 91.225.

C) The solutions for ADS-B OUT are rapidly changing, as is the guidance from the FAA about what is needed in an experimental. 2020 is still 1,700 days away. In just the last 6 months, prices have fallen about $1,000. All Dynon can say right now is that we will support multiple solutions for ADS-B out, and we will push hard to solve the issue at a Dynon price. No point in promising that we will do "something" if we can't talk about when and what.

Our recommendation remains that unless you otherwise have an IFR navigator in your plane, you should wait to equip with a 91.225/91.227 legal solution. Not having this causes no operational restrictions for the next 4.5 years, and gives you time to investigate the solutions that come to market in that time.

In the end I ended up replacing the GTX327 with a Dynon (Trig) transponder and installing the Dynon ADSB "in" box. The 327 was sold to a friend with an old Cessna 150. The installation took about 20 hours but many hours were spent just getting to know the 10. I didn't build this one so removing some of the instrument panel, seats, side walls, et took some time. The Trig was mounted on the pilot side on the sub panel. I utilized the same RG400 cable, just needed to cut off the old BNC and install the TNC. The Dynon ADSB "in" box was installed under the co pilot seat. The new antenna for "in" was very close to the box. Running the wires to the dual Skyview was not a big deal, the instructions were pretty straightforward. I have to say the configuration on the Dynon is very simple and well done. The hardest part (read that as frustrating) was removing the entire radio stack to get to the back of the GTN. I needed to add a wire to pick up the serial data.

I know if I waited there would be many other solutions but my wife likes to fly with me and she insists on traffic and weather. Heck, I even have it in my Just Highlander.

Thanks for all the suggestions

Gary
