The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria required skills and knowledge range statement and the Assessment Guidelines for the Training Package

Overview of assessment

A person who demonstrates competency in this unit must be able to test and troubleshoot communication and RF navigation 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 testing and troubleshooting applications including the timely involvement of supervisors or other trades associated with aircraft communication and RF navigation 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 testing and troubleshooting is essential This is to be demonstrated through application across a range of aircraft communication and RF navigation systems and components listed in the Range Statement 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 aircraftsystem faultfinding 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 at least one system and its major components from each of Groups to Groups and may be omitted where the listed systems are not applicable to the enterprise and the general associated components in Group as listed in the Range Statement This shall be established via the records in the Log of Industrial Experience and Achievement or where appropriate an equivalent Industry Evidence Guide

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
