Thank you both of you.
The standart roster in USA seems to be 5 duty & 2 leave, but if your 4th day on duty is a night shift the next "sleeping day" is included on the 5/2 roster? or you can end your roster 5 in night shift and then you have 5 + sleeping day + 1off?
Any FAA atco on the fórum to confirm this point?
Regards
