Which of the following systems helps identify potential security threats before they materialize?

The Advanced Passenger Screening System plays a crucial role in aviation security by analyzing passenger information before they arrive at the airport. This system assesses various data points, such as passenger travel history, affiliations, and other risk-related factors, to identify individuals who may pose a security threat. By conducting this pre-screening, security personnel can take proactive measures to address potential risks, ultimately enhancing the overall safety of flights.

In contrast, the other systems mentioned serve different purposes within aviation. For instance, an Incident Management System focuses on managing and responding to incidents after they occur rather than preventing them beforehand. The Aircraft Registration System is primarily concerned with maintaining records of aircraft ownership and ensuring that aircraft are properly registered, which does not directly relate to identifying threats. The Air Traffic Control System is involved in the safe coordination of air traffic but does not have a security screening function for passengers. Thus, while all these systems contribute to operational safety in aviation, the Advanced Passenger Screening System is specifically designed to identify and prevent security threats before they can manifest.
