What an assessment for MEA297 must cover
35 assessable components: 4 elements (20 performance criteria), 11 performance evidence and 4 knowledge evidence requirements. 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 avionic systems and components

- 4.6Perform physical installation of avionic components according to applicable maintenance manual
- 4.7Reinstate system to correct operational condition in preparation for testing and calibration or adjustment, as necessary
- 4.8Complete and process required maintenance documentation according to standard organisational procedures
Performance evidence
- locate and identify avionic system components comprising: - very high frequency (VHF) communications system - very high frequency omni-range (VOR) radio navigation system - basic audio system, such as intercom and audio selection - stand-alone global navigation system (GNS) - air traffic control (ATC) transponder - automatic dependent surveillance-broadcast (ADS-B) - emergency locator transmitter (ELT) system - automatic direction finding (ADF) navigation system, which may be omitted if not relevant to the organisation
- remove and install at least one from each of the following basic avionic system components: - transmitters and receivers - antennas and antenna cables - control boxes and frequency selectors - speakers - switches
- use approved maintenance documentation and aircraft publications relating to the avionic system being maintained

Questions about assessing MEA297
What does an assessment tool for MEA297 need to cover?
To satisfy the Principles of Assessment and Rules of Evidence, an assessment for MEA297 needs to address all 35 unit components: 4 elements with 20 performance criteria, 11 performance evidence requirements, 4 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 MEA297?
Auditori pulls the current release of MEA297 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 MEA297 — with no card and no subscription required. After that it's pay-as-you-go per unit.
Can I check my existing MEA297 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 MEA297, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
