Which of the following is NOT a method for screening in-flight supplies?

In the context of aviation security, passenger interviews are not a method used for screening in-flight supplies. Screening procedures are designed to ensure the safety of aircraft and passengers by examining items that are brought on board, such as food, drinks, and other supplies.

Visual checks, hand searches, and X-ray equipment are all practical means employed for inspecting these supplies. Visual checks involve looking for any suspicious items or irregularities, hand searches allow for a tactile examination of supplies, and X-ray equipment can identify potential threats concealed within items. In contrast, passenger interviews are more focused on assessing the intentions and behavior of individuals rather than directly inspecting in-flight supplies. This distinction underscores why passenger interviews do not fall under the category of screening methods for supplies.
