| | 2.2 | RF navigation or communication system is functionally tested in accordance with maintenance manual for evidence of serviceability or malfunction while observing all relevant work health and safety (WHS) requirements |
| | 2.3 | System calibration or adjustments are performed in accordance with maintenance manual, as appropriate |
3. | Troubleshoot RF navigation and communications systems | 3.1 | Available information from maintenance documentation and inspection and test results is used, where necessary, to assist in fault determination |
| | 3.2 | Maintenance manual fault diagnosis guides and logic processes are used to ensure efficient and accurate troubleshooting to line replacement level |
| | 3.3 | Specialist advice is obtained, where required, to assist with the troubleshooting process |
| | 3.4 | RF navigation or communication system faults are located and the causes are clearly identified and correctly recorded in maintenance documentation, where required |
| | 3.5 | Rectification requirements are determined |
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 RF and communications system being maintained
recognition of system and component defects/external damage, correct installation, and attaching hardware (including cabling/harnesses/transmission lines) and security in:
external communications systems:
HF
UHF
VHF
SATCOM and microwave
internal communications systems, including:
intercommunication
cabin intercommunication data systems (where applicable to the enterprise)
cabin network services (where applicable to the enterprise)
CVR
information systems, such as air traffic and information management systems, and network server systems (where applicable to the enterprise)
RF navigation systems:
ILS
VOR
ADF
GNS
ACARS
ELT systems
applying logic processes, taking and interpreting system measurements to accurately and effectively isolating malfunctions within the systems
performing system testing to isolate system faults and assess post-maintenance serviceability.
It is essential that system testing procedures, cleanliness requirements and safety precautions applicable to the aircraft communication and RF 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 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 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
explaining the basic layout (block diagram level), function and operation of:
external communications systems:
HF
UHF
VHF
SATCOM and microwave
internal communications systems, including:
intercommunication
cabin intercommunication data systems (where applicable to the enterprise)
cabin network services (where applicable to the enterprise)
CVR
information systems, such as air traffic and information management systems, and network server systems
RF navigation systems:
ILS
VOR
ADF
GNS
ACARS
ELT systems
explaining basic principles/functions relating to the above systems and associated with:
electromagnetic radiation and propagation
basic AC and DC circuit theory
digital fundamentals
analogue fundamentals
antenna characteristics
transmission line characteristics
WHS requirements
system and component maintenance requirements and troubleshooting procedures
relevant maintenance manuals
relevant regulatory requirements and standard procedures.
Competency should be assessed in the workplace or simulated workplace using tools and equipment specified in the maintenance manuals. It is also expected that applicable general and special purpose tools, and test and ground support equipment 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 at least one (1) system and its major components from each of the following groups:
control and sensing associated with cockpit radio, ground and flight crew communications including FM and AM modes of operation in the HF, UHF, and VHF bands, microwave systems and SATCOM
passenger communications, CVR, audio integration system, cabin intercommunication data systems and cabin network services (may be omitted if not applicable to the enterprise)
information systems, such as air traffic and information management systems, and network server systems (may be omitted if not applicable to the enterprise)
ILS, VOR, ADF, GNS, emergency beacons and ACARS
and the following general associated components:
antennae, impedance audio matching devices, microphones and headphones, transmission lines, computer controls, line replaceable units, transmitters/receivers and indicators.
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.
Individuals being assessed who have already attained any of MEA214 Inspect, test and troubleshoot aircraft basic communication and radio navigation systems and components, MEA215 Inspect, test and troubleshoot advanced aircraft communications systems and components, MEA216 Inspect, test and troubleshoot instrument landing systems and components, MEA234 Inspect, test and troubleshoot aircraft global navigation systems and components, MEA276 Maintain basic aircraft communication and radio navigation systems and components and MEA289 Maintain basic light aircraft avionic systems and components, will have covered Element 1 plus a significant proportion of the Performance Criteria for Elements 2 and 3 and will have covered common Range of Conditions variables. The Log of Industrial Experience and Achievement records relating to these units may be accepted as also meeting the evidence requirements for this unit in the applicable areas.
