Depends on your base and what fleet you are on. Assuming you start on the Q400 expect anything from 40hrs in the winter to max hours in the summer. I have found that mine normally fall around the 60-70 mark with the odd manic month.
All in all, pretty good and you are home every night and no more night flights like my previous outfit......yeehah! I rarely get night stops but I am sure you will get someone on here saying they get loads....that is not the norm.
Hope this helps.
