Aligning Crew Scheduling Rules With Human Physiology

This document is a guide that outlines a methodology for improving crew scheduling rules to enhance efficiency while managing fatigue risk. It begins by discussing the limitations of strict rules designed to limit fatigue, emphasizing the need for operational flexibility under a Fatigue Risk Management System (FRMS). The guide presents a structured nine-step methodology for optimizing crew planning solutions using bio-mathematical fatigue models. The steps include preparing a baseline solution, appraising maximum potential by relaxing rules, and evaluating the impact of these changes on crew efficiency and fatigue risk. The methodology encourages iterative testing and validation to ensure that new rules do not compromise safety. It concludes by noting that skilled analysts are required to implement these changes effectively and highlights the potential for significant improvements in both crew efficiency and fatigue management. The guide also mentions that leading airlines have successfully applied similar methodologies, resulting in substantial reductions in fatigue risk.
