Description
This unit of competency applies to aircraft alternating current (AC) and direct current (DC) electrical systems, including power generation, control and distribution circuits and lighting systems. It involves evaluation of systems for compliance with design and performance standards and with airworthiness regulatory requirements within both civil and military environments. Also covered is documentation of the evaluation process within management systems, such as configuration management (CM) and integrated logistic support (ILS).It is suitable for people working as paraprofessionals within aircraft design teams, within the engineering departments of aircraft maintenance organisations or employed within Continuing Airworthiness Management Organisations (CAMOs) and Approved Engineering Organisations (AEOs), and for those pursuing qualifications or careers in those fields.This unit is used in workplaces that operate under the airworthiness regulatory systems of the Australian Defence Force (ADF) and the Civil Aviation Safety Authority (CASA).
Notes
Elements and Performance Criteria
1. Prepare to evaluate aircraft electrical system
  • 1.1 Confirm and apply safe electrical working practice
  • 1.2 Review the effects of electricity on humans and identify dangerous high currents and voltages and regulatory requirements related to extra low, low and high voltage applications and relate these to aircraft electrical system operation and maintenance
  • 1.3 Determine parameters and context of applications and purpose of evaluation
  • 1.4 Confirm personal functions and responsibilities, team and support functional group interdependencies and communications
  • 1.5 Confirm that tasks and responsibilities are appropriate to qualifications and delegations and that appropriate support, including technical and professional assistance, is available
  • 1.6 Determine chain of responsibility for the activity evaluation, reporting arrangements and timelines
  • 1.7 Identify work health and safety (WHS) and regulatory requirements with particular emphasis on safety, codes of practice, performance requirements and standards, including airworthiness regulatory requirements for aircraft electrical systems, risk management and organisational procedures
2. Identify principles and techniques required for evaluation of aircraft electrical system
  • 2.1 Identify features and functions of aircraft electrical AC and DC systems and components
  • 2.2 Review aircraft electrical system design and layout requirements and techniques
  • 2.3 Identify system power generation and control requirements
  • 2.4 Identify electrical distribution system circuit and protection requirements
  • 2.5 Identify interfaces with aircraft and avionic systems and their power requirements
  • 2.6 Identify internal and external aircraft lighting requirements
3. Evaluate aircraft electrical system and system components
  • 3.1 Evaluate proposed modifications to aircraft electrical systems and system components
  • 3.2 Evaluate aircraft electrical system and system component maintenance requirements
  • 3.3 Evaluate aircraft electrical system and system component reliability and defect history
  • 3.4 Evaluate proposed component substitutions
  • 3.5 Evaluate application for compliance with WHS Acts, regulations, codes, directives and standards/specifications, including those related to risk management
4. Report results
  • 4.1 Report results of scoping, principles and techniques identification and evaluation of applications
  • 4.2 Provide documentation, such as system schematics, wiring diagrams and data required by CM and/or ILS, and as required for compliance with airworthiness regulations
