Spot on
Flexpwr its called sleepyness well thats what i'm told by the experts, we tend to bundle it into fatigue, if i get a bad nights sleep tonight i may suffer from sleepyness. Very unlikely fatigue with the French Union and social rules protecting them unless it goes into that area where no one likes to go - self management of rest
How long were the crew in Rio, 24hr slip or more?.
Departure was 1900 local time, French time probably in the WOCL.
The transcripts suggested the FO coming in from his bunk rest was tired, sleep inertia?. Cpt would have had it for sure.
We'll never know
