This unit describes the skills required to analyse and apply a knowledge of simulator systems that is required to support a variety of applications including maintenance, fault finding, repair, and testing of simulators. This includes accessing and analysing relevant simulator systems information and implementing recommendations specific to simulator systems. In the context of this unit, simulators are used to replicate land, air, sea and undersea systems to facilitate training and development.The application of simulator systems knowledge is specific to a variety of component processes in simulator operations, including simulator systems maintenance and support to simulator operations.This unit was developed in a Defence environment but may be relevant to others who work in this field.The skills and knowledge described in this unit must be applied within the legislative, regulatory and policy environment in which they are carried out. Organisational policies and procedures must be consulted and adhered to.Those undertaking this unit would work independently, or as part of a team, with minimal supervision, while performing complex tasks, including complex problem solving, in a limited range of contexts.
