What should be logged and reported prior to embarkation regarding the PEM system?

The correct choice pertains to the importance of logging and reporting any damage to the PEM (Passenger Embarkation Management) system, specifically damage that exceeds 5 inches of strip. This threshold is critical because substantial damage can compromise the structural integrity and functionality of the boarding system, potentially leading to safety issues or operational disruptions.

By ensuring that any significant damage is reported before embarkation, it allows for necessary assessments and repairs to be conducted promptly, thereby maintaining a safe and efficient boarding process for passengers. Noting such issues beforehand is crucial for compliance with safety regulations and operational standards, protecting both the airline and its customers.

Though passenger complaints, missing boarding passes, and cabin crew assignments are all relevant aspects of flight operations, they do not pose the same immediate operational and safety risks that significant physical damage to the PEM system does. This distinction highlights the need for prioritizing the logging of substantial damage in the context of safe and effective embarkation procedures.
