Re: ADS-B traffic information

Jeff,

Ya I thought about that and will probably change it for a few flights to see what happens. The 3 mile traffic I saw earlier that's exactly what I thought so I didn't pay too much attention to it at the time. The thing that made me think something is off was today going into a fairly busy class C airport and I saw nothing. I was thinking maybe it had to do with my proximity to the destination airport and maybe filtering around the airports. When I flew in there were at least 10 aircraft within my visibility settings on the iFly. Before that not so much but around the airport there was definitely traffic running around and they never showed up on the iFly.

Re: ADS-B traffic information

If you don't get a tower until you're at 8K (what's that in AGL?) then you won't get any of the traffic that the towers are feeding you so you're essentially getting the same picture I am which is limited. And once you dip back below 8K for the approach, you picture gets cut again. I suspect you'll start seeing traffic with the 740 set to "Unlimited". I've never paid attention to it until now, but the 2nd number for traffic on the "Connected Devices" screen is labeled "Shown". I wonder if that tells you how many of the traffic reports are meeting the filter criteria, and therefore "shown" on the screen? If yours is zero, that might be telling you that none of the "seen" aircraft meet your filter settings.

Re: ADS-B traffic information

This was the other day with my SkyGuard ADS-B transceiver and iFly GPS set to unlimited...

Re: ADS-B traffic information

Old Pilot/Jeff,

8K MSL here is about 5K AGL. I'm in a bowl. I'm in a mountain valley, floor is about 3.5k and I have 7-9K peaks on all sides at about 5-10mi out. Once I'm up and into radar/radio/ADS-B coverage I have really good line of sight reception. The FAA's ADS-B coverage chart shows a dead spot here too and I've found it is fairly accurate. I've set it to unlimited and I'll keep an eye on it and see what happens. Maybe it all worked out just right to where I didn't meet the criteria of my display settings??

Around my local airport I don't expect to see much at all. I'm betting maybe 1 in 20 aircraft running around here has ADS-B installed. I'll play with it a bit and if I head up into a ADS-B coverage area I'll log the flight for Shane to review.

Re: ADS-B traffic information

Keep in mind the NavWorx is currently only a 978 out and 978 In. The Certified models do not currently support the 1090ES receive, so you will see less traffic. Without the 1090ES In option, you won't see those high-altitude heavies at 18-40k+.

I'd do like OldPilot says and set the Dist and Alt Visibility to "Unlimited". Then take it for a flight at a fairly nice altitude. You can also look on the screen for the ADS-B icon to see how far you are from it. There are also some online sources to see exact tower locations. Being in a bowl will dramatically affect your reception of the "Full ADS-B" picture. Possibly limiting you to other ADS-B out aircraft, which will be very limited.

Look forward to hearing back some results. On this is that ADS-B is basically all or nothing. If you are seeing Weather, then you are in range of traffic and should see it if it's out there and if you have the needed reception bands... Hope this helps and please keep us all posted..
