What an assessment for MEAAVI0009 must cover

25 assessable components: 3 elements (12 performance criteria), 4 performance evidence and 6 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 basic aircraft instrument systems and components

1.1Identify specific inspection requirements using maintenance documentation and modification status, including relevant system defect reports where relevant
1.2Check isolation tags and configure aircraft for safe system inspection and operation in accordance with maintenance manual
1.3Visually or physically check instrument 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 basic aircraft instrument 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 instrument system for evidence of serviceability or malfunction in accordance with maintenance manual
2.3Perform required calibration or adjustments to system in accordance with maintenance manual

3 Troubleshoot basic aircraft instrument systems and components

3.1Use available information from maintenance documentation and inspection and test results to assist in fault determination of identified issues
3.2Troubleshoot issues to line replacement level using maintenance manual fault diagnosis guides and logic processes
3.3Obtain required specialist or supervisory advice to assist with troubleshooting process
3.4Locate instrument system faults and identify and record causes of faults in required maintenance documentation in accordance with standard enterprise procedures
3.5Determine requirements for rectification of faults

Performance evidence

perform inspection, testing and troubleshooting on basic aircraft instrument systems and components, comprising a system and at least one major system component or line replaceable unit (LRU) from each of: • pitot or static systems and components, air speed indicators (ASIs), vertical speed indicators (VSIs), outside air temperature (OAT), and counter-pointer altimeters • directional gyros (DGs) and artificial horizons (AHs) (air and electrically driven) • turn and bank and slip or turn coordinators • direct reading compasses • remote reading gyro compass system components (may be omitted if not relevant to the organisation) • piston engine indication system components (direct reading measuring instruments and temperature indication) • gas turbine engine indication system components (may be omitted if not relevant to the organisation) • electrical systems indication (voltage, current, power and frequency) • basic fuel quantity indication systems and components • pneumatic or vacuum indication components
recognise system and component defects, external damage, correct/incorrect installation, connection of plugs, terminations, attachment hardware (including cabling/harnesses) and security in each of the following: • flight instruments • pitot or static systems • direct reading compasses • remote reading gyro compass systems (where relevant to the enterprise) • piston engine indication systems • gas turbine engine indication systems (where relevant to the enterprise) • electrical systems indication • basic fuel quantity indication systems • pneumatic or vacuum indication systems
perform functional testing by applying logic processes, taking and interpreting system measurements, using test equipment and appropriate wiring diagrams and manuals to isolate instrument system malfunctions and faults in the listed systems 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

the basic layout (block diagram level), function and operation of: • flight systems, including: - altitude (direct reading altimeters) - attitude including DGs and AHs (both air and electrically driven), turn and slip and turn coordinator - airspeed - OAT - remote reading gyro compass systems • piston engine indication systems, including: - direct reading temperature - direct reading pressure (e.g. oil pressure) - speed, including mechanical and electric tachometers - manifold pressure/boost, including aneroid, sylphon bellows and dual compartment types • gas turbine engine indication systems, including: - temperature and pressure - speed, including mechanical and electric tachometers - torque - fuel flow - vibration • auxiliary direct reading systems, including: - electrical - hydraulic pressure - pneumatic pressure and vacuum • basic fuel quantity indication
basic instrument system maintenance and testing requirements, and troubleshooting procedures
work health and safety (WHS) practices for the inspection, testing and troubleshooting of instrument system maintenance
the operating principles of the above systems and associated with: • atmospheric conditions; properties and effects on aircraft instruments and systems • pressure and temperature sensing elements and their use in aircraft instruments • gyroscopes and their use in aircraft instrument systems • electrical fundamentals • direct reading compass installations and calibration • calibration of remote reading gyro compass systems
maintenance manuals for the inspection, testing and troubleshooting of basic aircraft instrument systems and components
relevant regulatory requirements and standard procedures.

Foundation skills

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

Questions about assessing MEAAVI0009

What does an assessment tool for MEAAVI0009 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for MEAAVI0009 needs to address all 25 unit components: 3 elements with 12 performance criteria, 4 performance evidence requirements, 6 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 MEAAVI0009?

Auditori pulls the current release of MEAAVI0009 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 MEAAVI0009 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing MEAAVI0009 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 MEAAVI0009, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
