Screen articles by interpreting X-ray images


Application

This unit involves the skills and knowledge required to screen articles by interpreting X-ray images at a security controlled airport with screened air services, in compliance with relevant regulatory requirements of the Civil Aviation Safety Authority (CASA) and national operating standards.

It includes setting up and testing X-ray screening equipment, operating X-ray screening equipment, interpreting X-ray images, and taking appropriate action when weapons, explosives and prohibited items are detected.

This unit addresses aviation technical skill requirements (physical, mental and task-management abilities) related to aviation security duties that complement the non-technical skills of ground operations personnel, and contributes to safe and effective performance in complex aviation operational environments.

Operations are conducted as part of recreational, commercial and military aircraft activities across a variety of operational contexts within the Australian aviation industry.

Work is performed independently or under limited supervision as a single operator or within a team environment.

Licensing, legislative, regulatory or certification requirements are applicable to this unit.

Use for Defence Aviation is to be in accordance with relevant Defence Orders, Instructions, Publications and Regulations.
