Dynon, what is the current progress / status regarding the momentary ARINC 429 dropouts that some GNS430W-->ARINC 429-->SV flyers experience. On my way to Oshkosh I had several dropouts in quick succession which caused autopilot to auto switch out of NAV to Course mode. I spoke to some guys...

Make sure you have the latest software if you are using the SV-GPS 250. This software fixes a GPS bug that appeared in April. This GPS issue caused a GPS course error that translated to winds aloft being way off. I also experienced this and some auto pilot tracking errors. Kurt

If your ADS-B out (transponder) has a IFR GPS connected as the position source; like the GNS-430W, then you are good. If you are relying on the SV-GPS-250 as your ADS-B position source then you will need to upgrade. I am assuming you already have a Mode-S transponder.

Peter, I recently configured my Skyview Touch to take advantage of the increased Landing Gear contacts. If you follow the naming conventions ("GEAR", "GEAR1", "GEAR2", or "GEAR3") and status them correctly "UP" and "DOWN", any combination of "GEAR(x)" that is "UP" when you slow below IAS set...

You are correct to just change the sign's on the two coefficients as in your first reply. Just remember to save off your sensor definition file (SFG) so you can just re-load it after you do a firmware update. Kurt

Check your User log files. If the Date and Time column (Column D) shows "Unknown_Date_Time" then you need the newest version of software 15.4.4. The GPS Epoch event affects date/ time/ GPS course. There is additional info on other threads about this. Kurt

I just flew with 15.4.4 and it corrected the "Unknown Date & Time" in the user logs and the GPS Course / Winds aloft bad calculation. Thanks, Kurt

I just flew with 15.4.4 and it corrected the "Unknown Date & Time" in the user logs and the GPS Course / Winds aloft bad calculation. Thanks, Kurt

Let me know if you need me to send a diag. dump file? Kurt

I loaded 15.4.3 Software and flew this evening. It corrected the GPS Course and the Winds Aloft calculation, However, logfiles still show "Unknown_Date_Time" in the GPS Date & Time column. Dynon will have to answer this one?

You need to contact Dynon Support. They will send you a link to Version 15.4.3 that will correct the GPS issue. It should correct your "Unknown Time" and the GPS Course (Winds aloft) issue. Kurt

Based on another post regarding the "GPS250 missing time" I downloaded my User Data Files. I see the "Unknown Time" in the GPS Date & Time column. I am convinced my problem is associated with the needed GPS250 software update. Dynon? What do you think? Kurt

I would agree with you except why does the GNS430W show different from SV by 28kts? All the data is from same source( Skyview) except the GPS course. Why does the GNS430W gps course and the GNC250XL GPS course differ from SV GPS course by 7 degrees? Before about 2 weeks ago the GNS430W and SV...

I have some additional info that makes me believe this is a Dynon GPS issue. Perhaps related to the GPS time missing (parsing issue) on older GPS250 pucks. When I view the GPS Course on the GNS430W or my GPS250XL they agree with each other but the Skyview GPS Course is different; to the right...

I noticed on my last two flights the Dynon Skyview wind speed is off by ~25 to 30 kts.  The wind direction is correct as I compare it to the D-100 and the GNS430W.  I used to see all 3 be reasonably close to each other with the GNS430W exact same as Skyview.  Does the GNS430W not get all the...

The ELT needs a NMEA formatted GPS signal. If any of the other outputs are set to NMEA you can double up the connection match the baud rate on the ELT settings. The ACK has jumpers for Rx rate. Or, depending on what other GPS navigator you have you can move the ELT to an unused port on it...

If the fuel flow drops when the boost pump is ON you are getting air into your fuel lines. Probably between the Electric pump and the engine driven pump. Check lines for tightness and fuel stains. It is possible to have air sucking in without fuel leaking out (no stain). Another possibility...

You can move or remove any of the displays (Map, PFD, and engine) to any position (L, C, or R).  No problem having the PFD portion on the RH side of display. I think it is 50/50 when you have only 2 panels open.

Dynon, I have a D100 set up as my standby flight display as it is totally independent of the skyview system. My D100 is installed in my Glasair on the Future Vision instrument panel. This panel has the inserts canted to favor the pilots viewing angle (about 10 degrees). See attached photo...

Rob, Based on your description the problem has to be bad connection on the alternator side of the shunt, the ANL 60 fuse/ holder, alternator itself, or field wiring / field circuit breaker. Check all the connections between these points. Just because the alternator has been replaced does not...
