Skyview Touch failure
Wondering if anyone can add some thoughts on an odd thing that happened when I was flying my RV-12 SLSA yesterday and today.
At run-up I was checking the rpm drop from the ignition modules. I switched one off at a steady 4000 rpm to watch the drop. As I did so my fat finger also caught the other module and for a split-second both were off and the engine faltered until I quickly switched both back on. The engine never stopped.
After cussing myself I checked everything and all seemed normal except that Skyview rebooted. I repeated the engine run-up and checked the ignition modules again and the parameters were all normal. On the second repeated run-up Skyview froze and rebooted normally.
I was about to return to the hangar but on the way pulled over to a side area and spent about 15 minutes checking things over, as I would have done at the hangar anyway. Everything seemed normal and I couldn't see anything out of order.
On a 5000' runway I applied full power and all parameters were normal so I continued the takeoff and climb out was normal. Throughout the flight everything was normal except after about 15 minutes the Skyview suddenly went blank. It rebooted and stayed on for several minutes. I decided to return to the field which I'd kept close by.
The Skyview went blank and then rebooted. This time it stuck at the opening page. Normally as the RV-12 logo comes up you hear it say "Dynon Skyview", this time it stuck on that so it was "Duh-duhduhduh etc" instead of Dynon. When it blanked I also lost the radio.
As I approached the field I cycled the avionics switch and got the radio back. I checked all c/bs and all were fine. Skyview came back and stopped at the RV-12 screen. I checked for traffic, announced joining the pattern and flew it all the way to landing with no instruments at all. No EMS, altitude or airspeed. I haven't decided on a 'back-up' to the Skyview yet. The engine was fine and so I used my experience with the plane to reduce power and slow to familiar looking speeds/sounds, and attitude. I lowered the flaps which are a johnson bar. I kept the speed to what I felt was a bit higher than normal and it squeaked on slightly farther from the threshold than normal.
After shutdown I felt the screen and it did feel a bit warmer than usual but I did hear the cooling fan switch off with the master switch.
I waited about 15 mins to see if it needed to cool down and it didn't seem like it was ever really much warmer than usual.
I restarted Skyview using it's own internal power (master off) and it booted up normally. I shut down and repeated a couple of times and all seemed normal.
I'm wondering if the Skyview got overloaded trying to restart itself in the air? It had more problems each time until it finally hung up on the start-up screen. After total shut-down do you think that it cleared itself and was able to start normally?
When I inadvertently switched off the adjoining ignition module on run-up what might that have done to the Skyview , if anything, as far as telling it to reboot, if anyone knows?
I did have Foreflight on my iPhone as back-up to navigate and I'm currently trying to decide how to best back-up Skyview, other than having a second screen, which might also have had the same issue as the other screen? I'm thinking iPad or iFly GPS but haven't got there yet. Any thoughts?
It was my clumsy finger which caused the problem but I'm interested in any thoughts as to what Skyview did to itself from anyone with any experience with it.
I e-mailed Dynon Support last night with this summary. Today at the hangar I downloaded the diagnostic file from Skyview which has the last hour's flight recorded.
I started up and everything was normal. After 10 minutes in the air I got a large red X across the screen, with EMS frozen on the right (no map) and then "ADHRS FAIL". Skyview rebooted and I continued the flight with no other problems?except..just as I flared and the stall warning started to squeal, Skyview shutdown. It rebooted as I taxied in and I shut everything down as per normal.
My mechanic thinks my inadvertent split-second ignition module shutdown and the Skyview issue might be co-incidental.
The return flight was absolutely normal.
I thought about recording the last hour's diagnostic again but it asked if I wanted to overwrite the last and I decided to wait until I emailed yesterday's flight.
When I got home I called Dynon Support. They had said in an e-mail it might be an issue with a circuit board that 2010-2013 units had. They'll my serial# on the file I sent them but I bought my SLSA July 2014 so I think it should have the fix.
Next time at the hangar I'll download the diagnostic file for today's flight with the ADHRS Fail warning.
Dynon mentioned maybe sending the unit back to them but we agreed to wait and see what the diagnostic files indicate.
I'm a bit anxious as I really like the Skyview Touch
