Elements and Performance Criteria Pre-Content

Elements describe the essential outcomes of a unit of competency.

Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide.

Elements and Performance Criteria

1. Research and evaluate the types of aeroplane and rotary wing aircraft power plant and their relative advantages and disadvantages

1.1. The types of aeroplane and rotary wing aircraft power plant  are identified and compared in terms of relative advantages and disadvantages

1.2. Types of propeller  are identified and compared in terms of relative advantages and disadvantages

1.3. Turbojet and turbofan performance is compared in terms of relative advantages and disadvantages

1.4. Maintenance requirements for aircraft power plants are identified

2. Apply basic power plant and propulsion system selection processes

2.1. Given required aeroplane use and performance characteristics, an appropriate type of power plant is determined

2.2. An appropriate type of propulsion system is selected

2.3. Given required rotary wing aircraft use and performance characteristics, an appropriate type of power plant is determined

Required Skills and Knowledge

Required skills 

Look for evidence that confirms skills in:

  • applying basic power plant and propulsion system design characteristics

Required knowledge 

Look for evidence that confirms knowledge of:

  • basic power plant characteristics
  • basic propeller theory and characteristics
  • use of NDT in power plant maintenance
  • power plant maintenance requirements, including the use of engine condition monitoring

Evidence Guide

The Evidence Guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment 

A person who demonstrates competency in this unit must be able to identify and apply basic power plant and propulsion system design characteristics. 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, teacher'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 

This unit may be assessed off the job in a training environment equipped to provide exposure to the relevant aircraft design characteristics and to theory of flight. 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.

Method of assessment 

Guidance information for assessment
