Level 1 violations exceeded and were demoted

Hanging on a long-haul flight at night, and then oversleep the next morning, and overspeeding when approaching, has anyone encountered it?😭

Hey there! Do you enable VNAV before you go to sleep?

yes. I usually turn on VNAV after reaching cruising altitude.

This is something I strongly advise against doing for this exact reason!

You shouldn’t do that for the very reason you explained here 😬

That’s not a good idea. Because if you oversleep, then you’ll descend on your own which leads to guaranteed speed violations. In the future, I wouldn’t recommend VNAV until you wake up.

OK. I understand.
