Application

This unit describes the skills and knowledge required to identify and apply basic aeronautical scientific principles and techniques to aeronautical engineering situations. This includes identifying the range of aeronautical scientific principles and techniques, selecting aeronautical principles and techniques for applications, applying aeronautical principles and techniques to engineering tasks, and quoting results appropriately.

This unit applies to members of a design and development team or similar who support the design and development of aeronautical applications or to those working within the engineering department of an aircraft maintenance organisation.

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.
