Roster-induced fatigue risk may originate from the flight schedule itself, and then elevated further in the pairing construction. The risk could increase even more in the crew rostering process, then again in the re-disposition of work done during the roster maintenance phase, and finally of course be elevated even further by late roster changes at day-of-operation. Controlling crew fatigue risk, throughout the often quite complex crew management process, means keeping an eye on all of these process steps and then improving where you get the best return on your investment. It requires a fair amount of insights, good metrics, patience, grit and of course capable tools.
Jeppesen has compiled a document that attempts to capture and describe a best-practice for controlling crew fatigue, throughout the full crew management process. Please access it here through this link. Hopefully you find it useful in your own work when striving to contain and reduce your roster-induced fatigue risk. Enjoy.
