Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

Instructions to Assessors

Evidence Guide

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 aircraft electronic systems and components 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 inspection applications (including the timely involvement of supervisors or other trades) associated with aircraft electronic systems and components. It is essential that cleanliness requirements and safety precautions applicable to the system being maintained are fully observed, understood and complied with. Ability to interpret inspection procedures and specifications (allowable limits) and apply them in practice is critical.

Evidence of transferability of skills and knowledge related to inspection is essential. This is to be demonstrated through application across a range of electronic systems and components listed in the Range Statement. The work plan should take account of applicable safety and quality requirements in accordance with the industry and regulatory standards.

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 each type of system listed in Groups 1 to 7 in the Range Statement and at least one component for each listed system type (Groups 6 and 7 may be omitted where they are 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 .

Context of and specific resources for assessment

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, test and ground support equipment would be used where appropriate.

Method of assessment

Guidance information for assessment

Required Skills and Knowledge

Required skills

Look for evidence that confirms skills in:

Application of relevant occupational health and safety (OHS) practices

The use of approved maintenance documentation and aircraft publications relating to the avionic system being maintained

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

multi-function display systems (interface units, display generators, display units), i.e. head-up display systems (HUD), engine indicating and crew alerting systems (EICAS), flight management systems (FMS), ACARS, electronic flight instrument systems (EFIS), electronic centralised aircraft monitor systems (ECAM)

integrated modular avionics

inertial navigation systems (INS), inertial reference systems (IRS)

external communications systems - high frequency (HF), ultra high frequency (UHF), very high frequency (VHF), satellite communication (SATCOM), emergency location transmitter (ELT)

multi-function display systems (interface units, display generators, display units), i.e. HUD, ICAS, FMS, ACARS, EFIS, ECAM

integrated modular avionics

INS, IRS

external communications systems - HF, UHF, VHF, SATCOM, ELT

internal communications systems - intercommunication, Cockpit Voice Recorders, cockpit/cabin audio visual, data systems, cabin network services

information systems such as air traffic and information management systems and network server systems

radio frequency navigation systems - ILS, VOR, ADF, GNS

primary radar (navigation/weather) components and interface

ACAS components and interface

radio altimeter components and interface

DME components and interface

ATC Transponders.

Range Statement

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.
