What is a 'sequence' in the context of flight operations?

In the context of flight operations, a 'sequence' refers to a series of flight segments scheduled for a crew member to operate, spanning over one or more days, and concluding with a rest period in their home base or domicile. This concept is crucial in ensuring that flight crews adhere to regulatory requirements regarding duty time, rest periods, and overall scheduling.

Understanding a sequence helps crew members manage their workload effectively and supports compliance with regulations that govern aviation safety and crew member well-being. It is important for flight attendants to be aware of their sequences to maintain optimal performance and safety standards during their shifts.

The other options don't accurately capture the definition of a sequence. A flight route represents a singular path, not the series of flights involved in a sequence. Maintenance schedules pertain to the upkeep of aircraft rather than crew scheduling. Checklists, while vital for pre-flight safety procedures, do not involve the operational scheduling of flight segments.
