Calibrating the AOA is a good idea on any plane new to you so you know it was done properly but bear in mind there is a separate setting for the minimum airspeed at which the AOA alert is active. The installation instruction recommend setting that to a number 5-10 knots below actual stall so you...

The main problem causing the delays is the fact that all of this must be run through the FAA for any certified aircraft. Dynon has no control of FAA scheduling.

There was an outage at least in the southeast last week. I was getting radar data for both regional and national according to the ADSB 472 but no textural weather at all. I also have another ADSB weather source and it showed the same thing. The outage was with FAA. All working normally again as...

You should email Dynon Support directly. They will respond if you do.

Take a look at the serial port where the position data comes from the Garmin. Make sure it is showing traffic on the port and no errors. Do you by chance have a Dynon GPS antenna (even the VFR only one)? If so check the assignment of the serial ports and make sure your Dynon shows POS1 for the...

This approach does not offer vertical navigation. The only published minimums are LNAV. The LNAV+V you are getting is exactly that...you are getting the LNAV offered by the approach but the vertical is advisory only. Furthermore, it is only offered to the final approach fix. After the FAF you...

The setting you are looking for is is under Serial connections in System. You have 5 serial ports. Port 5 is probably the GPS antenna (GPS 2020 or GPS 250). If you have a Dynon transponder it will be on another port. You are looking to find ADSB 472. This is the ADSB receiver. It is possible to...

The ADSB 472 is only a receiver. It only displays ADSB information received (traffic and weather) and displays that on the Dynon. It has no part in ADSB out for the aircraft. You can use the ADSB 472 without a transponder. I use mine in an aircraft with a Mode C transponder. My ADSB out...

Check every connection between the magneto and the EMS 220. It is almost certainly a bad connection "making and breaking". Verify the ground connection as well.

Check with Dynon Tech Support but I believe the system will work normally. The Skyview Classic and HDX run the same operating system. The firmware on the HDX moves the engine instruments to the bottom internally but I believe all external items are identical. Should talk to your Classic just fine.

With all of these symptoms I would be looking for bad grounding. Check all connections but pay very close attention to the grounding strap between the engine and the fuselage. Check fasteners are tight and remember to pull on the wire as it goes into the connectors. I would also recommend you...

Your results will be better if you safely drain the tanks before calibration. Additionally if you drain them by disconnecting the engine supply and pumping into containers (all components grounded) the added benefit is you will have numbers for the actual usable fuel in each tank.

The installation manual shows the ADSB 472 is a serial device. As such, it's data flows to one of the five serial ports. It does not use the Dynon network. The network hubs do not interface with the serial ports.

Unfortunately for your argument, logic is not what it comes down to. The FAR's are very clear about who is allowed to do which activities to a certified aircraft. The list of maintenance activities an owner/pilot may perform on a certified aircraft is extremely short and does not allow firmware...

Any linear potentiometer can be used. I needed one with much longer travel for the Glasair I built. I needed it to have 3" travel. Got one from Ebay that had about 5" so I didn't have to try to construct a tiny bellcrank just for the sensor. The calibration in the Skyview is the same since it...

That confirms your ARINC 429 module is working and getting the correct data. This is an interesting issue. The system worked flawlessly in my Glasair. The only obvious difference for me was I was always fully on speed at glideslope intercept (Navy carrier habits) so my speed was 68 KIAS. Perhaps...

Is the HSI depiction magenta or green? If the 440 is in ILS and the Skyview is receiving that analog data, the HSI will be green as ILS is analog. Can you post a screenshot or photo?

Ricardo, You may want to consider Force Network Load. That should find the servos and you will be able to calibrate if needed.

Dynon Tech Support will answer by email if you contact them but I do not think fuel flow is part of the calculation. I believe it uses density altitude, RPM, and Manifold pressure. A likely culprit is not having a temperature reading which would cause density altitude problems. Do you have a...

If memory serves the default number in the HDX system is 65000. It will get you in the ballpark. Just to be safe do not consider your fuel flow or fuel computer numbers accurate for the first flight. Takeoff with full (visually verified) tanks and fly for one hour. Land and refill. Adjust the K...
