What an assessment for MEAAVI0018 must cover

26 assessable components: 3 elements (12 performance criteria), 4 performance evidence and 7 knowledge evidence requirements, plus 3 foundation skills. An audit-defensible tool maps every question and task back to these — that mapping is the coverage matrix Auditori generates alongside the assessment.

Elements & performance criteria

1 Inspect secondary radar systems and components

1.1Identify specific inspection requirements using maintenance documentation and modification status, including system defect reports
1.2Check isolation tags and configure aircraft for safe system inspection and operation in accordance with maintenance manual
1.3Visually or physically check secondary radar system components for external signs of defects in accordance with maintenance manual while observing all relevant work health and safety (WHS) requirements
1.4Identify and report defects in accordance with standard enterprise procedures

2 Test or adjust secondary radar systems and components

2.1Prepare aircraft and system for application of power or system operation in accordance with maintenance manual
2.2Perform functional testing of secondary radar system for evidence of serviceability or malfunction in accordance with maintenance manual while observing WHS requirements relating to ground testing
2.3Perform required calibration or adjustments to system in accordance with maintenance manual

3 Troubleshoot secondary radar systems

3.1Use available information from maintenance documentation, inspection and test results to assist in fault determination
3.2Troubleshoot to line replacement level using maintenance manual fault diagnosis guides and logic processes
3.3Obtain required specialist or supervisory advice to assist with the troubleshooting process
3.4Locate secondary radar system faults and identify and report causes of faults in required maintenance documentation
3.5Determine requirements for rectification of faults

Performance evidence

 perform inspection, testing and troubleshooting on aircraft secondary radar systems and components during scheduled or unscheduled maintenance for at least one of the following secondary radar systems and its major system components/line replaceable units (LRU):  air traffic control (ATC) transponder  radio altimeter  distance measuring equipment (DME)  doppler navigation system  airborne collision avoidance system (ACAS)  automatic dependent surveillance-broadcast (ADS-B)
 recognise system and component defects, external damage, correct/incorrect installation, connection of plugs, terminations, attachment hardware (including cabling/harnesses/transmission lines) and security in one of:  DME components and interface  radio altimeters  ATC transponders  doppler navigation system  ACAS  ADS-B
 perform functional testing by applying logic processes and taking and interpreting system measurements to accurately and effectively isolate system malfunctions within the system, and assess post-maintenance serviceability
 apply testing procedures, cleanliness requirements and safety precautions at all times, and as relevant to the system/s being maintained.

Knowledge evidence

 component attachment methods
 the basic layout (block diagram level), function and operation of:  DME, including components and interface  radio altimeters  ATC transponders  doppler navigation system  ACAS  ADS-B
 basic principles/functions relating to the listed systems and associated with:  basic alternating current (AC) and direct current (DC) circuit theory  digital fundamentals  analogue fundamentals  radar fundamentals  transmission lines, waveguide and antenna characteristics
 pulse system maintenance requirements and troubleshooting procedures
 work health safety (WHS) practices for aircraft secondary radar systems and components
 maintenance manuals for aircraft secondary radar systems and components
 relevant regulatory requirements and standard procedures.

Foundation skills

Reading skills: to interpret maintenance manuals, inspection procedures and specifications (allowable limits).
Writing skills: to record and report on defects and faults and their causes.
Numeracy skills: to interpret and communicate technical information and take and interpret system measurements.

Questions about assessing MEAAVI0018

What does an assessment tool for MEAAVI0018 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for MEAAVI0018 needs to address all 26 unit components: 3 elements with 12 performance criteria, 4 performance evidence requirements, 7 knowledge evidence requirements, and the foundation skills. A coverage matrix mapping each question and task to these components is what an auditor looks for.

How does Auditori generate an assessment tool for MEAAVI0018?

Auditori pulls the current release of MEAAVI0018 from training.gov.au and generates a complete package: candidate assessment, assessor guide with model answers and observation criteria, and a coverage matrix mapping every component. A suitably qualified person then reviews and approves the draft in a built-in workflow — consistent with ASQA's guidance on AI use in VET — before export as branded PDF and editable Word.

Is the first assessment tool really free?

Yes. Every new account includes one free credit — enough to generate the complete assessment tool for MEAAVI0018 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing MEAAVI0018 assessment instead of generating a new one?

Yes — upload your existing assessment or learner guide and Auditori maps it against every element, performance criterion, PE and KE of MEAAVI0018, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
