The "current" rostering system is an abomination... upgrading to abominationV.2 doesn't sound promising.
Having said that... I've been reading many an article lately on shift workers health, sleep deprivation, and Pilot health.... it's all not good.
The rosters we operate here at EK are unique in the airline industry, flying widebodies on short-haul, long-haul, and ULR all in the same month.. and at all hours of the day and night. It is in fact slowly killing us all at an alarming rate.
This may have been posted before, but I would encourage anyone with a few minutes to participate in the Harvard School of Medicine Pilot Health Survey.
Pilot Health Study
I can guarantee it will be far more effective, and seen by enlightened people who care, than the sorry excuse we have for a Fatigue Monitoring Program.
