Elements and Performance Criteria
ELEMENT |
PERFORMANCE CRITERIA |
1. Inspect inertial navigation and reference systems and components. |
1.1. Isolation tags are checked and aircraft configured for safe system inspection and operation in accordance with the applicable maintenance manual. 1.2. Inertial navigation and reference system components are visually or physically checked for external signs of defects in accordance with applicable maintenance manual. 1.3. Defects are correctly identified and reported. |
2. Test/adjust inertial navigation and reference systems and components. |
2.1. Aircraft and system are prepared in accordance with applicable maintenance manual for the application of power/system operation. 2.2. Inertial navigation and reference system is functionally tested, in accordance with maintenance manual, for evidence of serviceability or malfunction. 2.3. System calibration or adjustments are performed in accordance with maintenance manual, as appropriate |
3. Prepare for troubleshooting. |
3.1. Relevant maintenance documentation and modification status, including system defect reports, where relevant, are used to identify an unserviceability. |
4. Troubleshoot inertial navigation and reference systems |
4.1. Available information from maintenance documentation, inspection and test results is used, where necessary, to assist in fault determination. 4.2. Maintenance manual fault diagnosis guides and logic processes are used to ensure efficient and accurate troubleshooting . 4.3. Specialist advice is obtained, where required, to assist with the troubleshooting process. 4.4. Inertial navigation and reference system faults are located and the causes of the faults are clearly identified and correctly recorded in maintenance documentation, where required. 4.5. Determine rectification requirements. |

Overview of assessment |
A person who demonstrates competency in this unit must be able to inspect, test and troubleshoot inertial navigation and reference systems and components while observing all relevant safety precautions. |
Critical aspects for assessment and evidence required to demonstrate competency in this unit |
The underlying skills inherent in this unit should be transferable across a range of inspection, testing and troubleshooting applications (including the timely involvement of supervisors or other trades) associated with inertial navigation and reference systems and components. It is essential that system testing procedures, cleanliness requirements and safety precautions applicable to the system being maintained are fully observed, understood and complied with. Ability to interpret inspection procedures and specifications (allowable limits) and apply them in practice is critical. Evidence of transferability of skills and knowledge related to inspection, testing and troubleshooting is essential. This is to be demonstrated through application across an inertial navigation and reference system and its components. The application of testing procedures should clearly indicate knowledge of system operation, the relationship of individual components and the links with other systems (if applicable) within the limits of the aircraft/system fault finding guide before undertaking any action. The work plan should take account of applicable safety and quality requirements in accordance with the industry and regulatory standards. A person cannot be assessed as competent until it can be demonstrated to the satisfaction of the workplace assessor that the relevant elements of the Unit of Competency are being achieved under routine supervision on an inertial navigation system and at least one major system component/line replaceable unit. This shall be established via the records in the Log of Industrial Experience and Achievement or, where appropriate, an equivalent Industry . |
Context of and specific resources for assessment |
Competency should be assessed in the workplace or simulated workplace using tools and equipment specified in the maintenance manuals. It is also expected that general and special purpose tools, test and ground support equipment would be used where appropriate. |
