Assessment tool

Version 1.0
Issue Date: May 2024


This unit requires application of hand skills, test equipment and knowledge of pulse, analogue and digital theory to repair or overhaul pulse system components from aircraft control and distribution systems.

Applications include control and distribution system components from fixed and rotary wing aircraft that are repaired or overhauled in aviation maintenance workshops.

This unit of competency is part of the MEA40610 Certificate IV in Aeroskills (Avionics) workshop training pathway. It covers the competencies required to repair or overhaul components of aircraft control and distribution systems. Repair of circuit boards is covered by MEA262B Modify/repair aircraft component single layer printed circuit boards and MEA263B Modify/repair aircraft component multi-layer printed circuit boards.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

The Evidence Guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment

A person who demonstrates competency in this unit must be able to inspect, test, troubleshoot and align/adjust circuitry of components from aircraft display, control and distribution systems in accordance with maintenance manuals and regulatory/industry procedures while observing all relevant safety precautions.

Critical aspects for assessment and evidence required to demonstrate competency in this unit

The underlying skills inherent in this unit should be transferable across a range of testing, aligning and troubleshooting applications (including the timely involvement of supervisors or other trades) associated with aircraft display, control and distribution system component repair and overhaul. Ability to interpret inspection and testing procedures and specifications (allowable limits) and apply them in practice is critical. It is essential that testing procedures, cleanliness requirements and safety precautions applicable to the system being maintained are fully observed, understood and complied with.

Evidence of transferability of skills and knowledge related to testing, aligning and troubleshooting is essential. This may be demonstrated through application across a representative range of the components listed in Groups 1 to 5 in the Range Statement. The application of testing procedures should also clearly indicate knowledge of system operation before undertaking any action. Knowledge of system operation and the relationship of individual components will be necessary to supplement evidence of ability to troubleshoot component faults. The work plan should take account of applicable safety and quality requirements in accordance with the industry and regulatory standards. Use of high precision, high reliability soldering techniques and handling of components, including application of anti-static equipment, must be demonstrated.

A person cannot be assessed as competent until it can be demonstrated to the satisfaction of the workplace assessor that the relevant elements of the unit of competency are being achieved under routine supervision on a representative range of components from systems listed in Groups 1 to 5 in the Range Statement that are 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 .

Context of and specific resources for assessment

Competency should be assessed in the work environment, using tools and equipment specified in maintenance documentation. It is also expected that general and special purpose tools and test equipment would be used where appropriate.

Method of assessment

Assessment should be made across a sufficient number of components to establish the ability to apply attained skills and knowledge across the full range of display, control and distribution system components with the aid of applicable maintenance manuals and data.

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

Required skills

Look for evidence that confirms skills in:

applying relevant occupational health and safety (OHS) practices

using approved repair/overhaul manuals, procedures and processes relating to aircraft display, control and distribution system components

recognising the serviceability state and repair or overhaul requirements for components from:

digital electronic instruments/display systems

digital flight controllers and directors

digital automatic flight control system (AFCS)/autopilot systems

flight management systems

analogue components of control and distribution systems

applying logic processes, using test equipment and appropriate wiring diagrams and manuals to isolate component faults

performing component testing to isolate/confirm component fault and assess post repair/overhaul serviceability

correctly aligning components listed above to operate within prescribed specifications

correctly interpreting digital instrument display indications, information and symbols

Required knowledge

Look for evidence that confirms knowledge of:

component and system operation

explaining the basic function and operation of components as follows to enable testing for fault isolation/confirmation, to determine repair or overhaul requirements, and serviceability status post repair or overhaul:

digital electronic instruments/display system components

digital flight controllers and directors

digital AFCS/autopilot system components

flight management system components

analogue components of control and distribution systems

explaining basic principles/functions, relating to the above systems/components and associated with:

advanced analogue fundamentals including video display generation techniques

digital fundamentals

AC and DC electrical systems

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.

Note

Range statements listed below are numbered to facilitate specification of the assessment requirements included in the Evidence Guide

Display, control and distribution system components

Display, control and distribution system components may be from the following aircraft systems:

1. Display systems, including electronic flight information systems (EFIS), electronic indicating and crew alerting system (EICAS) and electronic centralised aircraft monitoring (ECAM)

2. Automatic flight control

3. Autopilots (digital and analogue)

4. Flight director (digital and analogue)

5. Flight management

Application of this unit may relate to:

scheduled or unscheduled maintenance

individual or team-related activities

complex testing and adjusting of components, and where this is undertaken, may be carried out under supervision at the appropriate level

Procedures and requirements

Procedures and requirements refer to industry standard procedures specified by manufacturers, regulatory authorities or the enterprise

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
