Assessment Conditions
This unit may be assessed on the job, off the job or a combination of both on and off the job. Where assessment occurs off the job, that is, the candidate is not in productive work, then a simulated working environment must be used that reflects realistic workplace situations and conditions. The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team.
Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate ethnicity, age, gender, demographics and disability.
Assessment methods must be by direct observation of tasks and include questioning on underpinning knowledge to ensure its correct interpretation and application.
Assessment may be applied under project-related conditions (real or simulated) and require evidence of process.
Assessment must confirm a reasonable inference that competency is able not only to be satisfied under the particular circumstance, but is able to be transferred to other circumstances.
Assessors must be satisfied that the candidate can competently and consistently:
review features, functions and context of aeronautical engineering graphics
develop orthographic, isometric and other 3-D graphical representations and techniques for mechanical, fluid, electrical and electronic system representation
represent aeronautical components and assemblies using sketching and computer graphics
represent aeronautical components and features using a comprehensive range of standard conventions and graphical techniques
represent a range of aeronautical systems using standard graphical representations for wiring diagrams and system schematic diagrams
engage appropriate technical and professional assistance for advice as required
report results of review and the application of graphics techniques and provide documentation, images and files
maintain accuracy of performance (over time and in a range of workplace relevant contexts) together with application of underpinning knowledge.
Assessment may be in conjunction with assessment of other units of competency where required.
Assessors must satisfy the requirements of the National Vocational Education and Training Regulator (Australian Skills Quality Authority, or its successors).
Foundation Skills
Foundation skills essential to performance are explicit in the performance criteria of this unit of competency.
