I was doing a second lap around the pattern at KPAE, this time on autopilot. With heading hold on, I was rotating the heading hold knob with a keyboard shortcut in preparation for a turn to base, when everything went dark, I looked up at the overhead and every switch was in its off position. My engines were still running and I could hear them powering up but about 30 seconds later my FSX stopped responding.
I am absolutely amazed with the aircraft but I'm puzzled as to why this happened. Has anyone experienced anything similar or any idea what could have caused this?
EDIT: Fixed. After some troubleshooting, it turned out to be something unrelated to the 777. All is well now .
