List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. |
1. | Determine requirements | 1.1 | Communication and navigation system component defect reports (removal tags) or customer order are correctly interpreted and matched by part and serial numbers |
| | 1.2 | Circuitry is correctly prepared and connected to the applicable test equipment and is functionally tested or cycled through the prescribed test procedures in accordance with the maintenance documentation for evidence of serviceability or malfunction |
| | 1.3 | Modification status is clearly established to assist in determining the overhaul requirements for the components |
| | 1.4 | Extent of overhaul or repair is correctly identified and documented |
2. | Troubleshoot RF communication and navigation system components | 2.1 | Available information from maintenance records and inspection and test results is used, where necessary, to assist in fault determination |
| | 2.2 | Maintenance manual fault diagnosis guides and logic processes are used to ensure efficient and accurate troubleshooting |
| | 2.3 | Faults are located and the causes of the faults are clearly identified and correctly recorded in maintenance documentation, where required |
| | 2.4 | Fault rectification requirements are determined |
3. | Dismantle and inspect RF communication and navigation system components | 3.1 | Component parts are dismantled in accordance with maintenance manuals while observing all relevant work health and safety (WHS) requirements |
| | 3.2 | Component parts are assessed for serviceability in accordance with the relevant maintenance documentation |
| | 3.3 | Parts requiring specialist repair are tagged and repair instructions are accurately specified |
| | 3.4 | Parts lists are compiled and processed in accordance with standard enterprise procedures |
4. | Repair and/or modify RF communication and navigation system components | 4.1 | Component parts are repaired or replaced in accordance with the relevant maintenance documentation |
| | 4.2 | Modification of components or parts is undertaken, where required, by relevant manufacturers’ bulletins or procedures |
5. | Assemble, test and adjust RF communication and navigation system components | 5.1 | Assembly of component parts is carried out in accordance with specified tolerances and the applicable maintenance documents |
| | 5.2 | Assembled components are tested and adjusted/aligned in accordance with the applicable maintenance documentation using the appropriate test equipment |
| | 5.3 | Required maintenance documentation and modification records are completed and processed in accordance with standard enterprise procedures |
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:
applying relevant WHS practices
using approved repair/overhaul manuals, procedures and processes relating to analogue circuitry
recognising the serviceability state and repair or overhaul requirements for aircraft RF communication and navigation system components
applying logic processes, and using test equipment and appropriate wiring diagrams and manuals to isolate component faults
performing component testing to isolate/confirm component fault and assess post-repair/overhaul serviceability
correctly aligning components listed above to operate within prescribed specifications.
It is essential that component testing procedures, cleanliness requirements and safety precautions applicable to the system components being maintained are fully observed, understood and complied with. Ability to interpret inspection procedures and specifications (allowable limits) and apply them in practice across a range of inspection, testing, alignment and troubleshooting applications (including the timely involvement of supervisors or other trades) is critical.
Evidence of transferability of skills and knowledge related to testing, aligning and troubleshooting is essential. This may be demonstrated through application across a representative range of the components from systems listed in the Assessment Conditions.
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:
component and system operation
the basic function and operation of components of radio frequency communication and navigation systems to enable testing for fault isolation/confirmation, to determine repair or overhaul requirements, and serviceability status post-repair or overhaul
basic principles/functions relating to radio frequency communication and navigation system components and associated with:
advanced analogue fundamentals
digital fundamentals
AC and DC electrical systems
electromagnetic radiation
antenna and transmission line (including waveguide) characteristics
radio transmission/signal propagation and frequency modulation
GPS
satellite communications (industry specific).
Competency should be assessed in the work environment, or simulated work environment, using tools and equipment specified in maintenance documentation. It is also expected that general and special-purpose tools and test equipment would be used where appropriate.
The application of testing procedures should clearly indicate knowledge of system operation before undertaking any action. Knowledge of system operation and the relationship of individual components will be necessary to supplement evidence of ability to troubleshoot component faults. The work plan should take account of applicable safety and quality requirements in accordance with the industry and regulatory standards. Use of high precision, high reliability soldering techniques and handling of components, including application of anti-static equipment, must be demonstrated.
Assessment should be made across a sufficient number of components to establish the ability to apply attained skills and knowledge across the full range of RF components with the aid of applicable maintenance manuals and data.
The following conditions of assessment represent the requirements of the Regulators (ADF and CASA) and maintenance stakeholders and must be rigorously observed.
A person cannot be assessed as competent until it can be demonstrated to the satisfaction of the workplace assessor that the relevant elements and performance criteria of the unit of competency are being achieved under routine supervision on a representative range of components, applicable to the enterprise, from the following systems:
VHF communications
HF communications
UHF communications
satellite communications
ELT
ARINC Communication Addressing and Reporting System
intercommunication and public address
ADF navigation
VOR navigation
ILS
GPS.
This shall be established via the records in the Log of Industrial Experience and Achievement or, where appropriate, an equivalent Industry Evidence Guide (for details refer to the Companion Volume Assessment Guidelines).
Assessors must satisfy the requirements of the National Vocational Education and Training Regulator (Australian Skills Quality Authority, or its successors).
