This unit describes the knowledge and skills required to conduct fault finding and repairs to simulator computer systems and peripheral hardware. This includes analysing fault reports, identifying and rectifying faults, conducting functional tests and the documentation and certification processes. In the context of this unit, simulators are used to replicate land, air, sea and undersea systems to facilitate training and development.Computer systems may include Generic Simulator Computer Systems (x86 and x64), host computers, input/output systems, visual computers and instructor operating systems of simulators.Peripheral hardware may include instruments, visual display unit equipment, printers, hard drives and data storage devices, switches and routers.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. They would use discretion and judgement and take responsibility for the quality of their outputs.No licensing, legislative or certification requirements apply to this unit at the time of publication.
