I understand that the Captain in question resigned today.
I think it is quite appalling that the F/O would have let the situation continue - his / her inaction in my mind shows poor judgement. Not least as two crew equipment should have two functioning crew members - regardless of the conditions prevailing.
However, I believe it has been said here already: unknown duty time etc.? Not everything may be known about this, and maybe he was better off left sleeping than to take "command"??
Interesting topic.
