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 maintenance documentation and aircraft publications relating to the radio frequency and communications system being maintained
locating and identifying radio communication and navigation system components comprising:
HF and VHF communications
VOR, ADF and GNS
ATC transponders
ADS-B
ELT systems
locating and identifying applicable radio system antennas
recognition of system and component defects/external damage, correct installation, attaching hardware (including cabling/harnesses/transmission lines) and security in:
HF and VHF communications systems
VOR, ADF and GNS
ATC transponders
ADS-B
ELT systems
applying logic processes, functional testing and visual inspections to isolate malfunctions within the above systems
functionally testing listed systems to assess post-maintenance serviceability.
It is essential that system testing procedures, cleanliness requirements and safety precautions applicable to the basic communication or radio navigation system 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 and troubleshooting applications (including the timely involvement of supervisors or other trades) is critical.
Evidence of transferability of skills and knowledge related to inspection, functional testing and visual troubleshooting is essential. This is to be demonstrated through application across a range of basic aircraft communication and radio navigation systems and 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 attachment methods
connection of hardware and plugs
printed circuit boards
semiconductors
fibre optics
handling precautions for electrostatic sensitive devices
relevant WHS practices
the use of approved maintenance documentation and aircraft publications relating to radio communication and navigation systems and components
the general working principles of communication and navigation systems
explaining the basic system layout (block diagram level), function and operation of:
HF and VHF communications systems
VOR, ADF and GNS navigation systems
ATC transponders
ELT systems
ADS-B systems
radio frequency and communication system maintenance requirements and basic troubleshooting procedures
relevant maintenance manuals
relevant regulatory requirements and standard procedures.
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-purpose tools and test equipment found in most routine situations would be used where appropriate.
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.
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 system and at least one (1) major system component/LRU from each of the following groups:
HF and VHF communication LRUs, transmission lines and antennas
ADF, VOR and GNS navigation system LRUs, transmission lines and antennas
ATC transponders, transmission lines and antennas
ELT
ADS-B.
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).
Where the unit is to be used for CASA licensing purposes the Assessor must also meet the criteria specified in the CASR Part 147 Manual of Standards.
