Unit Descriptor

Unit descriptor 

This Unit is part of the Aeroskills Life Support and Furnishing AQF III and IV training pathways. It covers the competencies required to maintain and fit an Anti-G suit. Maintenance involves inspecting, testing, isolating faults, replacing parts, repairing and cleaning, while fitting involves adjusting the Anti-G suit to fit an individual. No licensing requirements apply to this unit at the time of publication.

This Unit is equivalent to PUADEFLS001A Maintain and fit Anti-G suits.

Application of the Unit

Application of the unit 

This unit requires application of skills and knowledge relating to the maintenance and fitment of Anti-G suits worn by aircrew and passengers in high performance aircraft.

Evidence Guide

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 maintain and fit Anti-G suits while using the correct PPE and observing all relevant safety precautions.

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 life support equipment maintenance activities. It is essential that Anti-G suit testing and inspection procedures, cleanliness requirements and safety precautions, including the correct use of PPE, are fully observed, understood and complied with. Ability to interpret maintenance and fitting procedures and apply them in practice is critical.

Evidence of transferability of skills and knowledge related to Anti-G suit maintenance and fitting is essential. This is to be demonstrated through demonstration of the ability to recognise faults and damage and perform appropriate repairs that are within the bounds of the individual's authority, and through the demonstration of correct fitting procedures on different sized individuals. The work plan should take account of applicable safety and quality requirements in accordance with the industry and regulatory standards.

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 routine supervision on a representative range of maintenance tasks and on the correct fitting of Anti-G suits to at least three different sized individuals. This shall be established via the records in the Log of Industrial Experience and Achievement or, where appropriate, an equivalent Industry

Context of and specific resources for assessment 

Competency should be assessed in the workplace or simulated workplace using materials, tools and equipment specified in the maintenance manuals and applicable procedures. It is also expected that general and special purpose tools and ground support equipment would be used where appropriate.

Method of assessment
