Which procedure must be performed during cargo preparation?

Preparing cargo for shipment is essential during cargo preparation because it ensures that all items are correctly packed, labeled, and documented according to safety regulations and airline standards. This procedure is paramount to ensure that the cargo is suitable for transport and complies with legal and operational requirements. By preparing cargo adequately, the risks of damage during transport and potential hazards during flight are minimized.

The other procedures listed, while important in their own right, do not fall under the specific practice of cargo preparation. Arranging seats in the aircraft pertains to passenger seating and comfort, which is separate from cargo management. Conducting pre-flight inspections is a crucial safety measure that involves checking the aircraft’s systems and structures but does not specifically address cargo handling. Taking passenger counts is related to logistics for boarding and managing passenger information rather than the specifics of cargo preparation.
