(a) Performance Evidence

          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:

          • locating and identifying electronic navigational system components, including altitude reporting systems (transponder, encoder and control unit), remote attitude displays and Inertial Navigation and Reference Systems

          • locating and identifying multi-function electronic displays, including electronic flight instrument system (EFIS), engine indicating and crew alerting system (EICAS), electronic central aircraftmonitor system (ECAM), flight management computer system (FMCS) and head-up display (HUD)

          • locating and identifying radio communication and navigation system components comprising ultra-high frequency (UHF); satellite communications (SATCOM); distance measuring equipment (DME); instrument landing system (ILS); global navigation system (GNS); radio navigation; traffic collision avoidance system (TCAS); radio altimeter (RADALT); and radio system antennas, including half dipole, slotted, loop and Marconi

          • locating and identifying primary and secondary radar system components, including transmission lines, waveguide and antennas

          • locating and identifying cockpit voice recorder system components, internal communications and passenger/cockpit audio/visual components

          • applying relevant WHS practices.

          It is essential that cleanliness requirements and safety precautions applicable to the system being maintained are fully observed, understood and complied with, as well as work practices associated with electrostatic sensitive devices.

(b) Knowledge Evidence

          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 basic knowledge of:

          • component attachment methods

          • connection of components and plugs

          • printed circuit boards

          • panel and rack mounting systems for electronic system components and LRUs

          • relevant WHS practices

          • the use of approved maintenance documentation and aircraft publications relating to the avionics systems and components being maintained

          • handling and maintenance precautions relating to gyroscopes, gimbals, electronic displays, airborne radar systems (including pressurized waveguides), electrostatic sensitive devices and radio installations

          • electromagnetic environment

          • relevant regulatory requirements and standard procedures.

          This part allows for different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included.

          Electronic system components include:

          • Panel and rack mounted electronic system components and LRUs of:

          • instrument navigation systems

          • communication systems

          • radio navigation systems

          • pulse operated systems

          • antennas

          • electronic instrument displays (where applicable to the enterprise)

          • automatic flight control systems (where applicable to the enterprise)

          • cabin entertainment equipment (where applicable to the enterprise)

          • on-board maintenance systems (where applicable to the enterprise)

          Procedures and requirements include:  

          • Industry standard procedures specified by manufacturers, regulatory authorities or the enterprise

          The assessment are composed of paper exams , interviews, and practical demonstrations, which the paper exam is the main testing. The selection of interviews and practical demonstrations are depending on the assessors’ judgment.

          • Competency should be assessed in the workplace or simulated workplace using tools and equipment specified in maintenance manuals. It is also expected that general-purpose tools, test and ground support equipment found in most routine situations would be used where appropriate.

          • An understanding of the attachment methods, connection of hardware, and the need for adjustment or calibration and system operation as they relate to the work must be demonstrated before undertaking any action. The work plan should take account of applicable safety and quality requirements in accordance with the industry and regulatory standards.

          • Evidence of transferability of skills and knowledge related to removal and installation is essential. This is to be demonstrated by application across a range of electronic system components as listed in the range of conditions.

          • An individual cannot be evaluated 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 sufficient components/LRUs of systems (at least five (5) including their antennas) to establish competency, as follows:

          • instrument navigation systems

          • communication systems

          • radio navigation systems

          • pulse operated systems

          • antennas

          • electronic instrument displays (may be omitted where not applicable to the enterprise)

          • automatic flight control systems (may be omitted where not applicable to the enterprise)

          • cabin entertainment equipment (may be omitted where not applicable to the enterprise)

          • on-board maintenance systems (may be omitted where not applicable to the enterprise).

          • This shall be established via the records in the Log of Industrial Experience and Achievement or, where appropriate, an equivalent Industry Evidence Guide.
