Apply computer-aided modelling and data management techniques to avionic engineering designs

This unit of competency covers the skills and knowledge required to apply computer-aided design (CAD) modelling and data management techniques to the design of avionic engineering products, processes, systems or services.

Application

Competency in this unit includes contribution to the full design process by the creation of models, graphics, documentation, and specifications representing avionic engineering products, processes, systems or services in support of the planning and design processes.

Work would typically be carried out as part of a design or engineering support team.

The data generated from the modelling process would be managed according to organisation procedures and contractual or agreed customer requirements.

Evidence Required

Overview of assessment

A person who demonstrates competency in this unit must be able to apply CAD modelling and data management techniques to a range of avionic engineering designs. Competency in this unit cannot be claimed until all prerequisites have been satisfied.

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria, including required knowledge, and be capable of applying the competency in new and different situations and contexts.

Assessors should gather a range of evidence that is valid, sufficient, current and authentic. Evidence can be gathered through a variety of ways including direct observation, supervisor’s reports, project work, samples and questioning. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency.

Context of and specific resources for assessment

Competency should be assessed in the work environment or simulated work environment using tools and equipment specified in maintenance documentation. It is also expected that general purpose tools and test equipment found in most routine situations would be used where appropriate.

The candidate must have access to all tools, equipment, materials and documentation required. The candidate must be permitted to refer to any relevant workplace procedures, product and manufacturing specifications, codes, standards, manuals and reference materials.

Method of assessment

This unit could be assessed in conjunction with any other units addressing the safety, quality, communication, materials handling, recording and reporting associated with applying CAD modelling and data management techniques to avionic engineering designs or other units requiring the exercise of the skills and knowledge covered by this unit.
