Standards? What is this word you speak of? We do not understand your crazy tongue!
Seriously, though...most places the duty hour limit for 2 man crew is 14, 16 augmented.
Most places adhere to the standard 8/24, 30/7, 100/30, 1000/12
STANDARD REST
9 hrs < 8 hrs duty
10 hrs > 8 to 9 hrs duty
11 hrs > 9 hrs duty
REDUCTION OF REST
9 reduces to 8 with 10 min next rest
10 reduces to 8 with 11 min next rest
11 reduces to 9 with 12 min next rest
Be prepared to know the rules inside out and defend yourself, the safety of your fellow crew and passengers. You will be pushed.
