(a) Performance Evidence

          Evidence required to express competency in this unit must be related to and fulfil all of the requirements of the elements and performance criteria under the indicated conditions of assessment, and must include:

          • applying relevant WHS practices

          • using approved maintenance documentation and aircraft publications relating to the avionic system being maintained

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

          • AC and DC power generation systems, including regulation, distribution, control and Cooling

          • battery installations and inverters

          • flight control and/or electro-hydraulic systems

          • engine ignition, starting, fuel distribution and control systems

          • internal/external lighting systems, including controls

          • doors

          • landing gear systems

          • anti-skid braking systems

          • master caution and warning systems

          • auxiliary systems (including ice/rain protection, fire detection, environmental control and pressurisation, waste and water, equipment and furnishings).

          It is crucial that inspection procedures, requirements for cleanliness and safety precautions relevant to the maintained system are fully perceived, understood and complied with.

          It is essential to be able to interpret inspection procedures and specifications (allowable limits) and apply them in practice (including the timely involvement of supervisors or other trades).

          Transferability Evidence of skills and knowledge relevant to inspection is important This is to be demonstrated through application across a range of aircraft electrical systems, components and hardware as specified in the Assessment Conditions.

(b) Knowledge Evidence

          Evidence required to express competency in this unit must be related to and fulfil all of the requirements of the elements and performance criteria and include knowledge of:

          • component attachment methods and connection of hardware

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

          • AC and DC power generation systems, including regulation, distribution, control and cooling

          • battery installations and inverters

          • flight control and/or electro-hydraulic systems

          • engine ignition, starting, fuel distribution and control systems

          • internal/external lighting systems, including controls

          • doors

          • landing gear systems

          • anti-skid braking systems

          • master caution and warning systems

          • auxiliary systems (including ice/rain protection, fire detection, environmental control and pressurisation, waste and water, equipment and furnishings)

          • WHS requirements applicable to the maintenance of aircraft electrical systems, including gas turbine engine high-energy ignition units

          • electrical system maintenance requirements

          • relevant maintenance manuals

          • relevant regulatory requirements and standard procedures.

(c) Assessment recommendation

          N/A

(a) Recommendation

          Different working environments and conditions that may affect performance are admissible in this field. Crucial 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.

          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 stated 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.

          • 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 related components in the following groups:

          • AC and/or DC power generation, regulation and distribution systems

          • battery installations and bus ties/interlocks

          • rotary and static inverters and TR units

          • air cycle air conditioning and pressurisation systems

          • flight and engine control systems

          • ignition and starting systems

          • fire/smoke detection and extinguishing

          • lighting

          • master and caution warning systems

          • equipment and furnishing

          • equipment cooling and ventilation

          • position indicating systems

          • fuel storage and distribution
