FAA ADSB Compliance Report is Perfect!

[BMW_X6M]

I just received the requested report back from the FAA on my 1 hour cross country flight last weekend. I am using the Dynon transponder with a GTN-650 position source. I am 100% compliant! It was darn near perfect with great signal levels and complete integrity of the data. Thank you Dynon for the transponder update which has made this possible. If only the rest of the thousands of airplanes flying near me would get this done as well.

I am also running full SV suite with the 650. I was wondering how one requests the ADSB compliance report. Thanks

I have the SkyView system and GTN-650 as well. I just sent a request for an ADS-B out compliance report to 9-AWA-AFS-300-ADSB-AvionicsCheck@faa.gov with my tail number. It came back with a full report (passed) in just a few hours.

Can you mention where your antenna is located on the airplane.

 

[Carl_Froehlich]

For my RV-10, the ADS-B receive antenna is mounted on the belly in the tail cone, to the left of the batteries. The Dynon ADS-B receiver is mounted there as well - so only a foot or so of RG-400 cable to connect the two. Transponder antenna is located under the right seat.

On my RV-9A I added the ADSB receiver antenna to the center of the bottom of the fuselage just aft of the baggage compartment. The transponder antenna is on the bottom right side under the passenger seat area. Both antennas are the shark fin style. I have had both in and out ADSB for 2.5 years and Dynon has made it easy and now updated the transponder a few versions back, to make it fully compliant. ADSB is worth every penny and is an enormous increase in safety to any pilot.

Been flying my RV9-A with Skyview and GTN-650 for two years now. When I originally purchased over three years ago, it was with the promise that Dynon would deliver on the software. I am very pleased with the entire Skyview stack of products and firmware updates, especially with ADSB.

Similar to California the Northeast corridor is very busy and having ADSB traffic and Wx is the way to go. Traffic is hard to see even with your eyeballs outside the cockpit. I almost always see traffic on the EFIS before my eyes catch up and confirm the location.

My Transponder antenna is centered behind the baggage bulkhead along with the remote transponder. The ADSB unit is located on the side wall of the fuselage in the same area. The ADSB antenna is about a foot away from the tail tie down ring with about 2-1/2 feet of spacing. Both antennas are shark fin types. Everything has worked well since the first flight.

On my composite KIS4 I put the ADS-B antenna on the right side of the fuselage just aft of the baggage compartment while the transponder antenna is on the left side about 3 feet further aft. Both the ADS-B and transponder modules are mounted about 2ft from their respective antenna connected with RG-400 coax. I have had this set up since March 2013 and, with my G430 providing the position source, the FAA report came back as 100% compliant.

I have an RV6A with Transponder Antenna under copilot seat and ADS-B Antenna under pilot seat. Inexpensive DeltaPopAviation blade antennas. Garmin GTN650 GPS. My compliance report took a couple hours and response email: "Requested report attached. Everything looks good." Nothing in report is red, so I am a happy camper!!

My assumption is that us Skyiew owners with the Dynon ADS B module, and still using the GPS 250 module, would not be able to get this FAA report, but when we move up to the GPS 2020 we can. So, would that be a correct assumption??..........Tom

 

[rvator51]

I would guess you would get it, but it would show non-compliant with 2020 rules,. This assumes you also have a ADS-B capable transponder or UAT installed besides the ADS-B receiver.

 

[tomscub]

I do have Dynon's mode S transponder, which should be okay.......Tom

 

[tomscub]

My reason for asking all of this is that I am showing ADS-B as functioning, with no Radar, (lower right corner of the Skyview moving map) but I am not seeing any traffic unless I get near class B or C airspace. I also show weather as up and running ( lower left hand corner of the Skyview moving map), and that seems to be working. I went to the coverage area, and my area looks like I should be seeing traffic. Also, when I look at the ADS B transmit and receive data counters, they show activity. I just can't believe that I am the only guy up there with a transponder. I was hoping that an FAA report would verify that my traffic is, in fact functioning..............Tom

tomscub - where are you in the country?

At this moment, the ADS-B system does not care whether you have a compliant GPS on board or not when it sees an ADS-B out signal and feeds you back the traffic picture. (That's due to slightly change in 2016, but we'll have an update that will allow SkyView customers that have yet to equip with an SV-GPS-2020 to keep receiving traffic).

But, the short answer is, for now, you should be receiving the same traffic portrait with SV-GPS-250 as you would with a GTN or SV-GPS-2020 as the position source. If that were the case, you should see "ADS-B OK" for the vast majority of the time. So if you're never seeing ADS-B OK and always seeing ADS-B NO RADAR, you may have a configuration problem. A few questions:

What version of SkyView are you running?

In SETUP MENU > TRANSPONDER SETUP, is the top status line yellow? Are all of the other settings correct, particularly your Tail number and Hex code? (you can check your hex code at http://registry.faa.gov/aircraftinquiry/NNum_Inquiry.aspx, then look for the "Mode S Code (base 16 / hex)" box.

First, Thanks to Dynon Support for helping here.  I have some answers to your questions.

I am running Skyview software level 13.0.3
In transponder setup the top line is "yellow".
The setting look correct to me.  Tail number and Hex code is correct, as verified with FAA Registry.

I jotted down the messages at the bottom of the map page on todays flight and they are as follows:
After takeoff, and at about 700' ASL, 300' AGL the ADS-B weather status changed, displaying the following:

ADS-B Status
Receiving
Nexrad Rgal
Age:  00:00
Nexrad Conus
Age:  00:06

But the Traffic side displayed:

ADS-B
No Radar

This condition did not change for the entire one hour cross country flight.  I was cruising at 3500', but on previous flights I have tried 5500", and still no joy.

I must have something wrong, I just don't know what it is.
Any assistance will be greatly appreciated............Tom

I think if the top line is yellow, it means there is a firmware update available for the transponder. Dont know if that will help or not with the traffic problem though.

 

[Dynon]

So the yellow transponder status means that there is a software update available for your transponder which should be applied. That's likely the reason that you're not receiving the full traffic portrait, as your transponder is likely not outputting the latest ADS-B data transmissions. There are full instructions in the installation guide on the different versions and what they mean (please read it, starting on page 11-22 of the SkyView System Installation Guide, always available from http://docs.dynonavionics.com). There are also on-screen helper instructions once you go into that menu.

Wow!! If this truly works, I will be deeply in your debt. I have been working on this problem for quite some time now, and all efforts have failed to provide any positive results, and I was beginning to question my installation. I have now printed the label, and will affix it to the transponder in the morning, after which, I will load the update to the transponder software. Then, I will go fly, and keep my fingers crossed. I also searched for other posts on the subject, to no avail. It's hard to believe that I am the only guy in the world with this problem. Hopefully, these post will help someone else to identify a similar issue. I will report back with the results. Thanks again.................Tom

 

[tomscub]

Okay! I now see ADS-B Radar "OK". It was a very quiet morning with no traffic around, but even at 3500' I had Radar for most of the area. One last verification will be to actually see traffic. Thanks for everyone's help.............Tom
