is there a best way to reboot HDX while flying?

[Lon]

There appear to be three ways to reboot an HDX display: turn the Master switch off and then on again; press and hold Button 1 until the display turns off, and then press Button 1 again; and press Buttons 1, 2 and 5 simultaneously, and then press Button 1 again. All three seem to work just fine while on the ground.

Suppose though I need to reboot my PFD while flying. I have a dual display system. Turning the Master switch off in flight is not an option, because doing that will turn off the PFD, the MFD and everything else including my radio. And I can't do that while flying.

So the choice comes down to (a) pressing and holding Button 1 only on the PFD, which will take a few moments to power down the PFD; or (2) pressing Buttons 1, 2 and 5 on the PFD only, which turns off the PFD immediately.

Apart from how quickly the PFD turns off, is there a difference between (a) and (b) in what happens inside the HDX, so that if it's done while flying, one would be better than the other? I would be rebooting, so after powering off the PDF, I'd want to turn it back on again as quickly as possible.

On page 3-26 of the Skyview HDX Pilot's User Guide is a chart showing the different/"hidden" button pushes available for Skyview HDX displays. Pushing buttons 1+2+5 is listed as a reboot of the display.

When I tried 1+2+5 yesterday, it turned the display off immediately, but it didn't turn the display on again. I may not have waited long enough for the actual reboot. I'll try it again this evening. Thanks

Tried it again, and 1+2+5 does reboot the display. It turns the display off immediately, but it takes a while for the display to come back on again. During the delay, the display is completely dark and looks as though it's entirely off. After several seconds, however, the reboot does occur. All in all, I'd say that if a reboot is necessary in flight, it'd be better to just press Button 1, hold it until the display powers down, and then press 1 again to turn it back on. That wouldn't take any longer than 1+2+5, and is easier to do while hand flying. Thanks again Andre.

Good news and thanks for this info, Lon! To be honest, I suspect both methods accomplish the same result. I like your rationale of focusing on one button during flight.

1+2+5 gets you out of a locked up situation.

Button 1 ON/OFF does the same except that if you need to reboot this might not work.

Maybe Dynon can comment.

My experience, which is extensive is "in flight" reboots have not been needed.....or not that I recall. I have maybe collectively 5000 hours of Dynon product hours. Maybe more.

Not sure this helps but it is my experience.

Thanks David - your input adds another layer of understanding. Nowhere in their instructions or guides does Dynon explain what to press with an HDX locked up situation. It appears pressing 1+2+5 is equal to turning the Master Power to the screen off, then on.

Dynon, care to clarify?

1,2,and 5 is actually a hardware reset, if SkyView is in a locked up state, button 1 usually doesn't work, but the reset will.

And to add....turning the master off with a backup battery may not achieve the reset, so if you had a locked up screen, 1,2,5, are your friends.

Also be aware the mini san disk usb keys can cause problems. Reboots while running and strange things. Avoid these and use the ones that come in the box.

Thank you djones/Dynon!

David -

I've read posts in other threads regarding this issue. The problem arises when the file sizes needed to upload are larger than the Dynon 16 GB USB sticks. Aren't there some 32 GB mini USB memory sticks that have been proven to work well with Skyview?

There are Kingston units I believe.

More than 16GB ...WOW, that is a lot of charting. Of course the US charts will be way more than ours down here in terms of volumes of aerodrome plates, so that may be the need for bigger sticks.

I've had the Sandisk USB problems on 8GB and 16GB sticks, switched over the Kingston a while ago and I'm not having any further problems.

I'm running 32GB sticks now, because with full US VFR and IFR (low and high) charts, it really is at the 16GB limit and there is no further room on the stick to capture screen shots or download user-data logs or diagnostic files. Most people would not need the IFR high charts (FL180 and above), but I use them way more often than I originally expected to.
