This unit of competency applies to modelling of aeronautical systems and components for civil or military aircraft. It is suitable for people working as design drafters and those pursuing paraprofessional careers and qualifications in aeronautical engineering at the paraprofessional level.

This unit of competency covers the application of aeronautical modelling techniques for aircraft, aircraft structure, systems and component design, modification or maintenance purposes. It includes consideration of the computer-aided engineering (CAE) purposes for which the model is required, such as initial design, modification design or maintenance and as a basis for generating orthogonal drawings and wiring, circuit and schematic diagrams.

This unit is used in workplaces that operate under the airworthiness regulatory systems of the Australian Defence Force (ADF) and the Civil Aviation Safety Authority (CASA).
