Description
Employability Skills
Learning Outcomes and Application This unit of competency applies to modelling of avionic 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 avionics.The unit covers the application of avionic modelling techniques for avionic component or systems design or maintenance purposes. It includes consideration of the computer-aided engineering (CAE) purposes for which the model is required, such as electrical or electronic component or system, printed circuit board manufacture and assembly 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).
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

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 competently and consistently:

review features, functions and context of avionic modelling

compare available software, functions and features

communicate, participate and negotiate with stakeholders, team, cross-function support groups and experts, appropriate licensed technicians and professionals

model using a comprehensive range of techniques

create dimensioned orthographic projections from model

extract dimensional properties from model

post-process model for analysis or physical modelling

complete work, commission and gain approval, document and report, and obtain sign-off

identify future developments in modelling.

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).
