Ok, for narrow bodies with no bunk;
Hard legal limits in the regulations, just like truck drivers and taxi drivers have.
Want to operate more than 8 hours stick time? Put a third crew member on.
Want crew to fly between 0200 and 0600? No problem, x hours free of duty prior and x hours free of duty after.
Max 28 hours duty in any 72 hour period.
Max 3 significant circadian shifts per 30 day roster. ( not earlies/ one day off/ lates/ one day off/ earlies etc etc)
Max of one single day off per roster, the rest as doubles etc etc etc
I agree 100% .
We can go there. If you commute and know it means you will have been awake for 19 hours on arrival then you are irresponsible imho. I have no idea if anyone commuted in this case.
