We examined aircrew fatigue during the following flight duty periods (FDPs) mentioned in the European Union (EU)
Flight Time Limitations (FTLs): night FDPs longer than 10 h and FDPs typical of disruptive schedules (early starts, late
finishes, and nights). An alternative way of classifying night FDPs was also examined to reveal possible subcategories
that warrant special attention.
