Maintain and fit Anti-G suits

This unit covers the competency required to maintain, repair and fit an Anti-G suit. Anti-G suits are usually worn by aircrew or aircraft passengers.Maintaining an Anti-G suit includes inspecting, testing, isolating faults, replacing, repairing and cleaning prior to placing the item back into service. Repairing an Anti-G suit is limited to fabric repairs and re-attachment of component parts consequently it excludes inflatable components.Fitting an Anti-G suit includes adjusting the Anti-G suit to fit the individual because the item is not an off-the-shelf issue.


The application of this unit in the workplace - the environments, complexities and situations involved - will be written during Phase II of the Review of the PUA00 Public Safety Training Package.

This text will be useful for the purposes of job descriptions, recruitment advice or job analysis; where possible, it will not be too job specific to allow other industries to import it into other Training Packages, where feasible.

Evidence Required

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Assessment must confirm the ability to correctly fit Anti-G suits to at least three different sized individuals with no corrective action required by supervisor; to recognise a range of faults, including incorrect manufacture; and to recognise limits of own authority.

Consistency in performance

Competency should be demonstrated over time with a range of fitments and maintenance of Anti-G suits.

Context of and specific resources for assessment

Context of assessment

Competency should be assessed in the workplace or in a simulated workplace environment.

Specific resources for assessment

Access to Anti-G suit; a live participant; and sewing machine tools and equipment for fitting and maintaining Anti-G suits.
