(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:

•   Applying relevant WHS practices

•   Using approved maintenance documentation and aircraft publications relating to the pulse system being maintained

•   Recognition of system and component defects/external damage, correct installation, connection of plugs, terminations, and attaching hardware (including cabling/harnesses/ transmission lines) and security in:

•   Radar (navigation/weather) components and interface.

•   ACAS components and interface.

•   Radio altitude components and interface.

•   DME components and interface.

•   ATC transponders.

•   ADS-B.

•   Doppler navigation system.

•   Applying logic processes, taking and interpreting system measurements to accurately and effectively isolate malfunctions within the systems.

•   Performing system testing to isolate system malfunctions and assess systems post-maintenance serviceability.

      It is essential that system testing procedures, cleanliness requirements and safety precautions applicable to the pulse 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 pulse systems and components listed in the Assessment Description and Procedure. 



(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.

•   explaining the basic layout (block diagram level), function and operation of:

•   Radar (navigation/weather) components and interface.

•   ACAS components and interface.

•   Radio altitude components and interface.

•   Distance measuring equipment components and interface.

•   ATC transponders.

•   ADS-B .

•   Doppler navigation system.

•   Explaining basic principles/functions relating to the above systems and associated with:

•   Basic alternating current (AC) and direct current (DC) circuit theory.

•   Digital fundamentals.

•   Analogue fundamentals.

•   Radar fundamentals.

•   Transmission lines, waveguide and antenna characteristics.

•   Pulse system maintenance requirements and troubleshooting procedures.

•   Relevant WHS practices, including those relating to ground functional testing of radar systems.

•   Relevant maintenance manuals.

•   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.

Pulse systems and components include:   

•   Navigation radar.

•   Weather radar.

•   Radio altimeter (RADALT).

•   Distance measuring equipment (DME).

•   Air traffic control (ATC) transponder.

•   Automatic dependent surveillance-broadcast (ADS-B).

•   Doppler.

•   Airborne collision avoidance system (ACAS).

•  Displays, indicators, control boxes, antennae, waveguides, transmitters and receivers, and line replaceable units (LRUs).

Procedures and requirements include:  

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

The assessment are based on combination of paper exams, interviewing, and practical demonstrations depending on the assessors’ judgement.

•   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, 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.

•   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 at least three (3) of the following systems:

•   Navigation radar.

•   Weather radar.

•   RADALT.

•   DME.

•   ATC transponder.

•   ADS-B.

•   Doppler.

•   ACAS.

•   And on at least one (1) item from:

•   Displays, indicators, control boxes, antennae, waveguides, transmitters and receivers, and line replaceable units (LRUs).

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