Unfortunately, I can't further expand on that but hopefully a 'colleague' is reading this and will help. I would expect to be on standby every once in a while.
Where I work a 4 day (it's the max I get) rotation is always a return to the main base every night, rest 2-3 hours and then fly to another destination. Some that live nearby go home, otherwise we rest at base as our employer gave us facilities for that.
Be aware that all the info I've given you are from a friend that works for ASLI, so it's second hand info.
