Omg…I´m scared to death. I´ve spawned cold & dark and all of a sudden the engine and everything turns on by itself and the plane was rolling backwards without me being able to make any inputs LOL.
I always want to be an alpha tester since last october…now I am 
No, Haven’t touched anything like that at all.
Almost the same here. I started on the parking in KLAX in DA62, and the avionics was already on. Anyway the flight was normal then, until the very end. I stopped and switch it off, and then I couldn’t start it again. And finally… CDT when going to main menu 
I’ve sent a request on Zendesk for more communication from the developers. This is becoming increasingly frustrating. Knowing that the fix isn’t working for everyone is deflating, it’s also making me think that I’ll start getting the issues again msyelf and I’m sick of being kept in the dark when I spent 12+ hours solidly trying to fix this yesterday. I feel like I’m doing their job.
Edit: For now, I think the best thing is to follow DucktapeEngineer’s original recommendations and to turn off ALL ground and air traffic until there’s more progress from the devs.
Edit: Perhaps Ground Aircraft Density is the main culprit, but depending on traffic density, other factors may cause it in smaller amounts.
It also failed to work for me, but I adjusted the slider from the Pause menu once the flight had started so perhaps it was too late. I’m going to try again after disabling it from the main menu. I might even restart the simulator so I can check it’s definitely “stuck”…
So after 10 flights where everything worked by eliminating AI ground airplanes, I came near EBBR with a lot of live traffic. Suddenly i heard a click and avianics was gone again (black screen). So it was much better with the workaround, but it is not the end of the story. Going the try the failure thing now.
I’m guessing Live/AI traffic is also causing it, so it’s now a case of trying the following:
Ground Aircraft Density to 0
Live Traffic - disabled in Data
Aviation Traffic - off
that’s my guess also… but i m also going to try that failure setting thing. Never did so much testing…
I’m starting to think that’s what the devs are relying on.
As for the failure thing, I’ve tried that multiple times and it hasn’t worked for me.
I think the devs took a real plane to the bahama’s with our money 
Just kidding, but i was expecting they communicate something…
Ha! I’m lucky that I’m only on Game Pass (although there’s apparently going to be a price raise but I haven’t received an email about it, where my friend has). I was saving up to buy the Standard Version outright to save money in the long run. The way things are going right now, that won’t be happening.
It may very well be a memory leak in their java script engine or whatever, that manifests quicker depending on multiple factors. Considering the FPS hit ground aircraft gives me, theres a lot of things happening codewise, and once in a while that may affect the instrument logic. Hell… it may even be a cause of other random problems like iffy autopilot and lost flight plans…
So even if “your” idea don’t fix it for all, it made it possible for me to fly the A320 without getting black screens… and I thank you for that!
That does cheer me up, thank you. 
Same problem with the M20R Mooney : I was entering my flight plan, and get the black screen. I could not restart it.
Same for me…
Set Ground Aircraft Density to 0 in Options > General > Traffic and have another try. @WandKarpfen2618
What an embarrassment to the dev team. Half of their “selling” features are broken and we have not heard a word from the devs 
I’m having similar issues, extremely frustrated!!! Yesterday I was in the middle of a flight in the Beechcraft Baron G58 and my avionics screen went completely blank and I had to reset the avionics switch to get it to work. This happened about 15 more times before I reached my Destination, unacceptable! Also, I can’t even fly the A320 because when I turn the batteries on or even the external power, I get nothing on the displays, therefore I cannot start the APU, so I can’t start the plane and can’t fly! There are a few indicator lights working on the overhead panel but that’s it!
Confirmed, Aviation Traffic also causes it. Flying along happily, decided to set AI Offline Traffic to 100 on both sliders. Immediately all instrumentation whacked out.
So, the following is now advised:
Options > General > Traffic:
General Aircraft Density to 0
Aviation Aircraft to Off
Obviously, you could set them to 10 or 20 if you want to see if it still breaks anything, but 0 / off is best for a trouble free flight.
I’m now guessing mass multiplayer sessions, like the one yesterday on Squirrel’s stream, will also cause issues. I had a multiplayer session last night but there was about 15 of us spread out and I had no ill effects.
This may explain why the General Aircraft Density fix alone worked for some and not others, because some still had aviation traffic enabled.
I also reckon that when I tested Live Air Traffic and had no ill effects, it was because the sim was not loading it in, it seemed really sparse (I have been having issues with Teredo, might be a factor).
Basically, any other aircraft is a threat.
(To confirm, I was in an A320)
Edit: Bug report updated with these findings.
