As per the submitted data, the Fatigue Management System is implemented in the airline. The system encourages the fatigue-related confidential reports by the crewmembers for any stage of the flight operations (the preflight, in-flight, post-flight one). For a number of quantitative indicators the system goes beyond the national aviation legislation (that is it ensures the improved conditions for the crewmembers). Since 2009, the airline has accumulated 450 000 flights with a total flight time of more than 1 million hours. Within the period, 70 fatigue-related confidential reports were submitted. The majority of them were proactive by nature – as the crewmembers reported the fatigue presence and were removed from duty until they felt fit for flight operations."
Euclideanplane I hope you have seen from some of the posts since you posted that your comments with respect show a lack of understanding about FRMS. I'm no sleep scientist (how many Airlines engage such folk) but with the early/late/night FDP's at FZ - there will be a fatigue issue. The FRMS was clearly not functioning.
