I was flying in the DA-40 NG. As I was approaching Ngari Gunsa Airport, this happened:
I’ve never experienced something like this before. Is this a bug, or is it just something than can happen during flight in real life?
What is the alerts message?
Did you check if alternator is on and the avionic busses?
Notice both COM & NAV radios are out as well, on BOTH Displays, so may well be an Avionics Bus power issue.
