Unit of Competency MEA325B - Weigh aircraft and perform aircraft weight and balance calculations as a result of modifications
Description This unit covers competencies required to progress from an Aircraft Maintenance Engineer at Certificate IV to the granting of a chosen Aircraft Maintenance Engineer Licence under CASR Part 66, in accordance with the licensing provisions in Section 3 Assessment Guidelines.The skills and knowledge covered by the units of competency listed in the Aeroskills Training Package for Aircraft Maintenance Engineer (Avionics or Mechanical as applicable) at Certificate IV are pre-requisite to the attainment of the elements of competency specified in this unit. This includes full coverage of the Civil Aviation Safety Regulation Part 66 Syllabus subjects/topics listed in Section 3
Employability Skills This unit contains employability skills.
Learning Outcomes and Application This unit requires application of knowledge regarding aircraft weighing and the use of relevant maintenance publications and modification data (where applicable) to weigh an aircraft and use the results to calculate centre of gravity and confirm that it is within limits.Applications include fixed and rotary wing aircraft.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

Elements of Competency Performance Criteria              
Element: Weigh aircraft
  • The requirement for aircraft weighing is determined.
  • Aircraft is weighed in accordance with the specified procedure
  • Aircraft weighing results are provided to the Authorised Airworthiness Representative (AAR).
       
Element: Calculate the weight and balance impact of a modification.
  • The new empty weight of the aircraft is determined and it is ensured that the weight is within the predetermined limits set by the AAR.
  • 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.
  • Maintenance records are updated with new figures.
       


Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

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 determine the requirement to weigh an aircraft, weigh it using a specified method and use the results to calculate centre of gravity. Safety precautions applicable to the weighing method involved are to be fully observed.

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 weighing of aircraft and calculation of centre of gravity is essential. The aircraft weighing work plan should take account of applicable safety and quality requirements in accordance with the industry and regulatory standards, especially in relation to aircraft jacking and levelling.

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 in the training environment.

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

Required skills

Look for evidence that confirms skills in:

Application of relevant OH&S procedures

Configuring aircraft for weighing

Weighing aircraft

Using weighing results to calculate centre of gravity

Required knowledge

Look for evidence that confirms 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

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.

Centre of Gravity calculation

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.

Application of this unit may relate to:

Scheduled or unscheduled maintenance activities

Individual activities or supervision of other personnel

Procedures and requirements

Refer to industry standard procedures specified by manufacturers, regulatory authorities or the enterprise

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
