Unit of competency

Modification History

Release 2. Equivalent to MEA701 Produce aeronautical engineering related graphics with amended prerequisite codes.

Application

This unit of competency applies to aircraft structure and to aircraft systems products, projects, and related system modifications. It is suitable for people working in aeronautical related design, drafting and maintenance support at the paraprofessional level.

The unit covers the application of graphical techniques for aeronautical engineering related purposes. Graphics techniques include sketching, computer graphics and the application of drawing standards.

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).

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).
