Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

MEA241B - Perform aircraft weight and balance calculations as a result of modifications

What evidence can you provide to prove your understanding of each of the following citeria?

Calculate the weight and balance impact of a modification

  1. The requirement for aircraft weighing is determined.
  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 Authorised Airworthiness Representative (AAR).
  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 AAR.
  4. Maintenance records are updated with new figures.
The requirement for aircraft weighing is determined.

Instructions to Assessors

Evidence Guide

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.

Method of assessment

Guidance information for assessment

Required Skills and Knowledge

Required skills

Look for evidence that confirms skills in calculating the effect on aircraft weight and centre of gravity of components installed during modification incorporation using weight and moment arm data.

Required knowledge

Look for evidence that confirms knowledge of mathematical formulae used to calculate centre of gravity of an aircraft.

Range Statement

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

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
