Elements and Performance Criteria

Range Statement

This field allows for different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included.

Centre of gravity of the aircraft is calculated:

Using the results obtained by weighing an aircraft

Using the weight and moment arm data for a modification

Procedures and requirements include:

Industry standard procedures specified by manufacturers, regulatory authorities or the enterprise

Performance Evidence

Evidence required to demonstrate competency in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria under the specified conditions of assessment, and must include:

applying relevant WHS procedures

configuring aircraft for weighing

weighing aircraft

using weighing results to calculate centre of gravity.

The underlying skills inherent in this unit should be transferable across a range of aircraft types. Ability to interpret the instructions for configuring and weighing aircraft is critical.

Evidence of transferability of skills and knowledge related to weighing of aircraft and calculation of centre of gravity is essential.

Knowledge Evidence

Evidence required to demonstrate competency in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria and include knowledge of:

types of weighing equipment used to weigh aircraft and associated safety precautions:

mechanical platform scales

electronic platform scales

electronic load pots

methods used to level aircraft for weighing

the importance of correctly configuring aircraft for weighing

mathematical formulae used to calculate centre of gravity.
