Assessment methods

(a) Recommendation

          This field allows different environments and working conditions that can affect the performance. the essential operating conditions that may be present (depending on the work situation, accessibility requirements, the candidate of the topic, and local industry and regional contexts) are included.

          Electrical systems and components include:

          • DC generators, and alternator/rectifier generators, and components of related single generator regulation and distribution systems

          • Motors

          • Actuators

          • Piston engine ignition and starting system components

          • Aircraft batteries

          • Specific components of DC electrical systems, such as flaps and landing gear

          • Aircraft lighting

          • Gas turbine engine igniter and starting systems

          Procedures and requirements include:

          • Industry standard procedures specified by manufacturers, regulatory authorities or the enterprise

(b) Description

          N/A

          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. 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 general purpose tools, test and ground support equipment found in most situations routine maintenance would be used where appropriate.

          • An understanding of the methods of fixing, connecting hardware, and the need for adjustment or rigging and operation of the system in relation to the work must be demonstrated before taking any action.

          • The work plan should take into account the applicable safety requirements and quality in accordance with industry and regulatory standards.

          • The following evaluation conditions represent the regulatory requirements (ADF) and the House and stakeholders maintenance and must be strictly observed.

          • 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 supervision at least one (1)           component each:

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

          • motors

          • actuators

          • system components engine ignition and starting piston

          • Aircraft batteries

          • specific components of electrical current systems, such as flaps, landing gear

          • Lighting aircraft

          • Lighter gas turbine engine and starting systems (can be omitted when not applicable to the company).

          • 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).

          • Assessors must meet the requirements of the National Education and Vocational Regulator.
