Which of the following best defines the "Elapsed time" in the context of a flight attendant's duty?

The correct definition of "Elapsed time" in the context of a flight attendant's duty refers to the time from the start of their duty until the end of the duty period. This encompasses all activities and responsibilities that a flight attendant undertakes during their assigned shift, which may include pre-flight preparations, boarding, in-flight service, and post-flight duties.

In contrast, the total flight duration from takeoff to landing pertains specifically to the airborne segment of the flight, whereas the preparation period focuses solely on tasks completed before passengers board. The time spent attending to passengers is one important aspect of a flight attendant's role but does not encompass the full scope of the duty period. Understanding elapsed time in this way helps ensure that flight attendants are aware of their responsibilities and the totality of their duty assignments.
