I read the instructions out loud (Turn off skyview for each static pressure increase/decrease) to the avionics guy I hired to check my altimeter and transponder accuracy. I watched him go at it for about 20 minutes shutting off the screen, changing pressure, turning on the screen, waiting for reboot, and recording the altitude... over and over again at each required altitude. I got bored and left him to do his thing, when I got back about an hour later he had a guilty look on his face and both ADHARS were failed.
The alarm the screens were getting after 10 seconds of being booted up was "dynon Adahrs fail internal error: multiple sensors"
At this point the plane was not flyable, and the avionics guy spent another 2 hours charging me for his time until I finally asked him to stop.
Turns out he had done the procedure on someone else's plane with skyview installed, and didn't bother turning the screens off each time, and he said it worked fine THAT TIME. When I left him alone, he started to change pressures without shutting down the skyview.
I have since got it going again, after about 40 reboots the Adhars stopped shutting down on the fail alert.
Apparently when testing, the reason you need to shut off the screen each pressure change is because of the way the skyview interacts and updates with gps speed, airspeed, pitot pressure, AOA pressure, static pressure, compas reading.... if there is a significant change in one parameter without the other, it assumes the adahrs has failed.
My Question to Dynon;
When able, can you please program in a button somewhere called "static system test" that shuts down all of the possible program problems if the pressure increases dramatically when the plane is not physically in motion?
This would dramatically decrease the test length and billable hours that the avionics guy charges (if he follows the instructions) and would stop this kind of error from happening.
Anyone else out there see this as somewhat of a priority?
