What is the proper procedure for a Flight Attendant after completing a preflight check?

The procedure after completing a preflight check emphasizes the importance of communication and accountability in ensuring passenger safety. Informing the Captain that the preflight check is complete allows for a coordinated understanding of the aircraft's condition before flight. Additionally, noting any discrepancies discovered during the check is vital for addressing potential safety issues before departure. This ensures that all relevant parties are aware of the aircraft's status and can make informed decisions based on the information provided.

The other options either lack the necessary communication to the Captain or neglect proper documentation processes. For instance, informing only the first officer does not provide the Captain with essential information, while leaving the area immediately disregards the responsibility to report findings. Documenting solely in the company logbook also misses the immediate communication aspect necessary for flights, suggesting a lack of team coordination. Therefore, the correct procedure fosters a thorough and collaborative approach to aircraft safety and operational readiness.
