Just woke up while en route on an overnight flight. I see I’ve been disconnected from the live server and notice the below 10,000 ft speed warning even though I’d left my device at cruise level and cruise speed. I use IF-Assistant, and was using VNAV as usual, and highly doubt I set the altitude to FL100 at any waypoint.
I would have received multiple violations and been system ghosted but as you can see in the screen shot, I didn’t so I’m wondering, what in the… and how to make sure this doesn’t happen again? It’s an absolute first for me on long hauls.
