Description
This unit of competency covers competencies required to progress from an Aircraft Maintenance Engineer at Certificate IV to the granting of a B2 Aircraft Maintenance Engineer Licence in the Avionics category under CASR Part 66, in accordance with the licensing provisions in the Assessment Guidelines.The skills and knowledge covered by the units of competency listed in the MEA11 Aeroskills Training Package for Aircraft Maintenance Engineer (Avionics or Mechanical as applicable) at Certificate IV are prerequisite to the attainment of the elements of competency specified in this unit.
Notes
Elements and Performance Criteria
1 Calculate the weight and balance impact of a modification
- 1.1 The requirement for aircraft weighing is determined
- 1.2 The new empty weight of the aircraft is determined and it is ensured that the weight is within the predetermined limits set by the CAMO
- 1.3 The new empty weight centre of gravity of the aircraft is calculated and it is ensured that the centre of gravity is within the predetermined limits set by the CAMO
- 1.4 Maintenance records are updated with new figures
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
Aircraft centre of gravity
Aircraft centre of gravity is determined:
using the weight and moment arm data for a modification
Application
The work can relate to:
scheduled or unscheduled maintenance and may involve individual activities or supervision of other personnel
Procedures and requirements
Refer to industry standard procedures specified by manufacturers, regulatory authorities or the enterprise

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.
Overview of assessment
A person who demonstrates competency in this unit must be able to use mathematical formulae to calculate aircraft weight and balance given weight and moment arm data and correctly update maintenance records.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
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 aircraft weight and calculation of centre of gravity 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 of the unit of competency are being achieved under supervision without intervention. This shall be established via simulated activities at the CASR Part 147 Maintenance Training Organisation and performance during observed workplace activities.
Context of and specific resources for assessment
Competency may be assessed in the workplace or simulated workplace.
