The briefing must occur at the beginning of each trip or when an FA is what?

The requirement for a briefing to occur at the beginning of each trip or when a flight attendant is assigned to or replaced underscores the importance of clear communication and the sharing of vital information among crew members. This ensures that all flight attendants are aware of their roles, any updates or changes to standard operating procedures, safety protocols, and specific passenger needs.

When a flight attendant is assigned to or replaced, it is crucial for the new crew member to be briefed on any pertinent details that may have occurred prior to their arrival. This could include changes in flight routes, updated safety information, or special instructions regarding passenger care. Therefore, conducting a briefing in this scenario enhances safety and operational efficiency and ensures that all team members are on the same page as they embark on the flight.
