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!

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 Conditions.
