Application
This unit of competency requires application of basic knowledge of avionic system function, design and layout, including typical electrical and instrument systems, during scheduled or unscheduled maintenance. Work may be performed individually or as part of a team.
The unit is part of Diploma and Advanced Diploma training pathways. It is used in workplaces that operate under the airworthiness regulatory systems of the Australian Defence Force (ADF) and the Civil Aviation Safety Authority (CASA).

Evidence of Performance
Evidence required to demonstrate competency in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria under the specified conditions of assessment, and must include:
sketching typical avionic systems at block diagram level.
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.
Evidence of Knowledge
Evidence required to demonstrate competency in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria and include knowledge of:
DC and AC power generation, control and distribution
aircraft electrical systems and their components
aircraft electrical system maintenance requirements
the atmosphere
use of synchros and servos
basics of analogue electronics
aircraft instrument measuring systems and their components
aircraft instrument measuring system maintenance requirements
air conditioning and pressurisation systems
air conditioning and pressurisation system maintenance requirements
types of aircraft oxygen systems and their applications
oxygen system maintenance requirements and related cleanliness and safety precautions.
Assessment Conditions
This unit shall be assessed off the job in a training environment equipped to provide exposure to the range of system types and components. The candidate must have access to all tools, equipment, materials and documentation required and must be permitted to refer to any relevant workplace procedures, product and manufacturing specifications, codes, standards, manuals and reference materials. The assessment environment should not disadvantage the candidate.
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.
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.
