Assessment Conditions
The unit may be assessed off the job in a training classroom environment using problems and application of knowledge relevant to aviation maintenance competencies and relevant knowledge requirements.
The unit must be linked in its assessment and application to those units that apply to actual maintenance of aircraft.
Evidence of knowledge about aviation maintenance settings in which mathematical techniques and physics principles, laws and techniques are applied is essential.
A person cannot be assessed as competent until it can be demonstrated to the satisfaction of the workplace assessor that the relevant elements and the performance criteria of the unit of competency are being achieved off the job in simulated settings.
