Application
This unit describes the skills and knowledge required to apply hand skills and use system and component knowledge, maintenance publications and test equipment to inspect, test and troubleshoot primary radar systems and components of fixed and rotary wing aircraft that have primary radar systems, such as weather radar, during scheduled or unscheduled maintenance. Work may be performed individually or as part of a team.
The unit is used in workplaces that operate under the airworthiness regulatory systems of the Civil Aviation Safety Authority (CASA) and the Defence Aviation Safety Authority (DASA).
Any other relevant legislation, industry standards and codes of practice within Australia must be applied.
