Which system is designed to detect and respond to security threats at airports?

The Airport Security Screening System is specifically designed to detect and respond to security threats at airports. This system encompasses a variety of technologies and procedures aimed at identifying prohibited items, ensuring passenger and baggage screening, and maintaining overall airport security. It includes devices such as metal detectors, x-ray machines, and explosive trace detection systems which contribute to a comprehensive security framework aimed at preventing potential threats before they can impact safety.

In contrast, other systems like the Runway Incursion Prevention System focus primarily on preventing accidents and ensuring safe aircraft movements on runways rather than directly addressing security threats. The Aircraft Maintenance System is concerned with the upkeep and operational readiness of the aircraft rather than airport security. Finally, the Air Traffic Control System is dedicated to managing the safe and orderly flow of air traffic, which is also not primarily focused on security threats specific to the airport environment. Hence, the Airport Security Screening System is the appropriate choice for addressing security concerns in an airport setting.
