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 | Display, control and distribution 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 display, control and distribution 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 display, control and distribution 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 display, control and distribution 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 display, control and distribution 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 aircraft display, control and distribution system components
recognising the serviceability state and repair or overhaul requirements for components from:
digital electronic instruments/display systems
digital flight controllers and directors
digital AFCS/autopilot systems
flight management systems
analogue components of control and distribution systems
applying logic processes, 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
correctly interpreting digital instrument display indications, information and symbols.
It is essential that system testing procedures, cleanliness requirements and safety precautions applicable to the display, control and distribution 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 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 as follows to enable testing for fault isolation/confirmation, to determine repair or overhaul requirements, and serviceability status post-repair or overhaul:
digital electronic instruments/display system components
digital flight controllers and directors
digital AFCS/autopilot system components
flight management system components
analogue components of control and distribution systems
basic principles/functions, relating to the above systems/components and associated with:
advanced analogue fundamentals, including video display generation techniques
digital fundamentals
alternating current (AC) and direct current (DC) electrical systems.
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 also 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 display, control and distribution system 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, that are applicable to the enterprise, from the following systems:
display systems, including EFIS, EICAS and ECAM
AFCS
autopilots (digital and analogue)
flight director (digital and analogue)
flight management.
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).
