Do not forget to put the system into test mode if you are doing pitot and/or static testing to prevent a GPS Assist attitude error. The error will clear on it's own with normal flight but you would need very good VFR weather and even then it will be disconcerting to some. Test mode prevents it...

There is a valid reason for the purple shading you see. The shading can occur in flight for any areas where ADSB data is no longer current/valid. The weather depiction is not removed in these areas but you know the information is no longer current in the area of the purple tint. Far easier than...

The weather is not received until the ADSB 472 sees the ground station towers. If the weather layer is not selected on, your map will look normal on the ground. If the weather layer is selected on the ground, the entire map will have a light purple hue although all other elements will be...

When you set Vx, Vy and Va in the Aircraft Information section of the Setup screens, you will get a corresponding X, Y and A on the airspeed tape. There is no audio so not really callouts but the notation will remain on the airspeed tape until you change them.

You can tell the system to display an Air Time value. The system has this as a Data option in the EMS setup. It will show your last flight time at start up and remain that until you pass about 20 knots of groundspeed which causes it to reset to zero during takeoff roll. Mine is displayed between...

You need to go to the settings (hold button 7 & 8). Then EMS settings for the EMS page (20, 50 or 100% size) you normally display. Now display Info and find Fuel Rem. Deselect it.

You need the larger box to the right of the HSI to show GNS 175 (this will actually be whatever you labeled the Garmin in the setup of your ARINC 429). This is the HSI source. It will toggle between none, Skyview and any other navigation source you have configured in your system. The smaller box...

I have a GNS480 feeding a Skyview in my Glasair so I can help. Be aware the 480 will only output ADSB+ format on Serial 3 which you need if you want to use it as your ADSB position source. Current 480 firmware is also required. Send me a PM if you like.

As long as you are actually seeing the vertical guidance output from the certified receiver, it will be correct. Some folks have not been diligent in confirming the HSI source is the Garmin and not the Skyview. Combining this with the different display with Firmware version 16 is where the...

Happy to discuss by phone and have spoken to Dynon reps twice at Oshkosh regarding this. Firmware version 16 took the Skyview VNAV vertical path from the vertical speed tape and moved it down to the HSI and making the appearance the same as RNAV LPV or LNAV+V vertical guidance. ILS glideslope...

The way I did it was to re-purpose one of the provided bugs. You are given a place to input Vx (max angle climb), Vy (max rate climb) and Va (maneuvering speed) which show up as individual marks on the airspeed tape X, Y and A. While I always reference angle of attack (old habits which kept me...

Are you positive you are showing the LPV guidance from the Garmin 175 and not the VNAV from the Skyview itself? When the firmware went to version 16 the VNAV presentation became the same as LPV. You must monitor the Skyview Flight Director source notations to differenciate. I considered it a...

Mike, I have the same setup you are planning. Since you already have the Echo UAT, you have a way to display the traffic/weather separate from the Dynon ADSB 472. I do not think you can do better than Dynon for your IFR, autopilot, flight director, engine monitor etc. setup. I chose to put a...

Sadly, Dynon does not allow the units to utilize the industry standard GDL 90 protocol for traffic and weather. It seems only Dynon and Garmin require proprietary protocols. When Dynon was having trouble during their move from the single band ADSB 471 to the current dual band 472 they considered...

On standard mags you need to have the resistors on the P lead. If you are getting high, fluctuating readings while running you need to increase the resistance.

Try going into the Hardware Calibration>Elev trim menu. Calibrate the elevator trim and then run the test.

GRT offers a "serial expander module". It plugs into an existing serial port and then provides three more. Could Dynon do something along these lines? Ideally, taking one serial port to add five more?

I think Rhino explains it very well.

Do not change this in your EFIS. When you file your flight plan with the Compassion Flight note, ATC will handle it that way. It is similar to airline flight numbers. Airline flight numbers have nothing to do with the registration (N number) of the airframe being used for that flight. Filing the...

Rolling the software back is possible but requires two files from Support and then you will need to do a Force Network Load to get all the modules back to the 15.4.7 version. I did this with my systems because I find the version 16 VNAV solution unsatisfactory in both arming and display. It...
