After updating to version 5.0 I am seeing text atrifacts being displayed in the lower corners of the screen. The screen is setup to show EFIF 2/3 on the left and Engine 1/3 on the Right. In the left corner the letter A is flickering. In the right lower corner the letter N The letters kinda...

I have the D180 bright option with the HS34. On power up I see the Dynon logo at normal brightness and then the D180 goes to a very dim display, like the back lighting is completely turned off. Recycling the power does the same thing. After 30 - 45 seconds, the display comes back to normal...

I never did find a solution to the AOA calibration issue. The airspeed accuracy seems very good on my Dynon and tracks closely with the mechanical airspeed indicator.

I have attempted several more times to calibrate the AOA. I have finally turned off the AOA display and moving on with other testing. I will revisit this after my 40 hours of flight testing. It is still strange how the indication seems to be reversed. Is there any chance that the internal...

Should I press the stall button at cruise airspeed and then slow and stall before the countdown timer reaches zero or should I press the stall button once slowed and just prior to stalling? Perhaps the speed change from 200 mph cruise to 50 mph for the stall is causing my issue.

I have verified the pitot and aoa lines are connected properly. The aoa line is the rear line in the pitot head and connected the the left most connector on the D-180 looking from the rear. Airspeed indication seems to be right on based on chase aircraft and GPS 3 way ground speed. I have again...

I have been flying my Glasair 1TD for about 15 hours now with the Dynon D-180, heated AOA/Pitot, HS34, Garmin SL30, Garmin 296. I tried to calibrate the AOA two days ago but was unable to get it to work. Starting at cruise airspeed 200 mph Entered AOA calibration menu Pitched aircraft up and...

Thanks for the quick reply. I will start checking the grounds and power as described. I will let you know. David Prince

I am in the testing phase of my new Glasair with the D-180 and sl-30 in the panel. When keying the mic I get a crackling noise in my ear when the Dynon unit is turned on. if the Dynon is off, the radio is crystal clear. I have shielded cable going to the headset and mic jacks and have routed...

I understand the three possible shunt locations. Of the three which is the most useful? A: Between Master Relay and ACLoad/Alt to measure amps to/from battery seem good. Zero would indicate aircraft load being handled by Alternator. B: Between MasterRelay/ACLoad and Alt to measure alternator...

I am getting to the end of building my Glasair. I have a Dynon 180 and a back ordered HS34. At this point should I wire the d180 per the maunal and then rewire when the HS34 ships. Most of the wires that go from the radios to the D180 look like they will need to be rewired to the HS34?

Is the HS34 Voice Audio output pin 25 on the upper D25 going to combine the D180 Efis DB25 Pin 18 Audio Out and the D180 D-37 Pin31 Audio Alert or will all three need to be mixed into the com panel Aux

I have purchased and received my D-180 and awaiting my HS34. I have used the line drawing of the HS34 to cut the panel (No backing out now) leaving just enough room between the D-180 and HS34 for the D-180 tray. I id not feel good about cutting the verticle leg off the tray. Are there any...
