      Aapplying relevant WHS practices, including those relating to gas turbine engine high energy ignition units. 

      It is essential that the system test procedures, cleaning requirements and safety measures applicable to electrical system are maintained are fully observed, understood and respected. Ability to interpret procedures and specifications (allowable limits) inspection and apply them in practice through a series of inspections, testing and troubleshooting applications (including the appropriate involvement of supervisors and other trades) is critical. Evidence of transferability of skills and knowledge related to the inspection, testing and troubleshooting is essential. This is to be demonstrated by the application in a wide range of aircraft electrical systems and components listed in the range of conditions.

Assessmen  methods

(a) Recommendation

(b) Description

       N/A

 

The assessment are based on combination of paper exams, interviewing, and practical demonstrations depending on the assessors’ judgement.Competition should be assessed in the workplace or place of work simulated using tools and equipment specified in the maintenance manuals. It is also expected that the tools of general and special purpose test equipment and ground support would be used where appropriate. 

•    The application of the test procedures should clearly indicate the knowledge of system operation, the relationship of the individual components and linkages with other systems (if applicable) within the limits of the failure of the aircraft / search system guidance before taking any action. The work plan should take into account the applicable safety requirements and quality in accordance with industry and regulatory standards. 

•     A person can not be assessed as competent until they can demonstrate to the satisfaction of the assessor workplace relevant elements and performance criteria of competence unit is carried out under routine monitoring in power looms, cables and connecting hardware, and each set in the range of conditions and at least one (1) main / online replaceable component unit (LRU), in each case as follows: 

•     DC generators and generators alternator / rectifier current, and control system components single generator and related distribution. 

•    System components engine ignition and starting piston. 

•    Specific components of electrical current systems, such as flaps and landing gear, including motors and actuators. 

•    Lighter gas turbine engine and commissioning of systems and components (can be omitted if not applicable to the company). 

•    Lighting aircraft. 

•    The main aircraft batteries (competition can be demonstrated by conducting a review of the battery). 

•    This is done through the records in the register of industrial experience and achievement or, where appropriate, a guide equivalent Industry Evidence (for details see the companion volume Assessment Guidelines).  

•    People who have already reached evaluated Keep MEA274 light aircraft electrical systems and core components have met the requirements of this unit with respect to the common range of varying conditions. The Registry of industry experience and accomplishments related records Keep MEA274 be accepted as meeting the requirements of evidence for this unit in public areas apply the basic light aircraft electrical systems and components.
