A typical day for an S/O. Well the whole crew meet at dispatch to review the paper work. Everyone is expected to go through the flight plan, wx and notams although the S/O is usually tasked with a detailed review of notams. On a rare occasion you may be asked your opinion on fuel but usually the decision will be made without your input. S/O's are not allowed to do walk arounds. On the 400 the S/O will do the safety check and then make the bunks. In flight you are only allowed at the controls in cruise. As well you will only be PF when the captain is in the seat. This is due to a CAD rule which came out a year or so ago. So most of your time will be PM involving fuel checks and radio work. All long haul flying on the 744 is 4 man crew. The rest is split in half although on the 15 hour LA-HKG flights it may be split up even further just so you are not in the seat for 7 hours + in one sitting. For the log book you log 50% of the time that you are in the seat. The job can be a little mind numbing however you can't beat the schedule.
