Rest to compensate for time zone differences CS FTL.1.235(b)(4): What does Eastward-Westward or Westward-Eastward transition mean?


For the purpose of CS FTL.1.235 (b) (4), ‘Eastward-Westward and Westward-Eastward transition’ means the transition at home base between a rotation in one direction and a rotation in the opposite direction, each involving a 4-hour time difference or more. 

At least 3 local nights of rest at home base are provided between such alternating rotations.

However, irrespective of where the transition occurs - at home base or away from home base, the operator, using safety risk management processes, should monitor rotations in opposite directions in terms of their impact on crew members’ circadian rhythm and fatigue, and provide sufficient rest to crew members between such rotations.
