Commander when in crew rest
Can someone give some insight into the responsibility of a commander when on crew rest.
What happens if a stuffup occurs while the skipper is stacking zzzzz's in the bunk. An example being an altitude bust en route.
Do governing authorities hold the commander responsible for such an incident when not on the flight deck. Have there been any cases of this?
Its something I have never understood especially considering that the crew are all required to have access to rest according to FTL's.
Just wondering.
