X-ray screening of passenger baggage is conducted at airports worldwide to prevent terrorist attacks and other acts of unlawful interference against civil aviation. Whether or not prohibited items are detected under X-ray examination depends both on the technology deployed and on human factors. While single-view imaging has been used for decades to screen passenger baggage, newer technology is based on multi-view and 3D imaging with automated explosives detection. However, the best equipment is of limited value if the humans who operate it are not trained appropriately. Thus, what should be considered for training to be effective when single-view, multi-view or 3D imaging is used for passenger baggage screening? In this article, Adrian Schwaninger and Sarah Merks provide recommendations for cabin baggage and hold baggage screening based on scientific studies conducted with screeners over the last 15 years.
