Description | |||
Employability Skills | |||
Learning Outcomes and Application | This unit involves the skills and knowledge required to defuel aircraft in compliance with relevant regulatory requirements and national operating standards.It includes conducting pre-operational checks on defueller vehicle and auxiliary equipment, positioning defueller vehicle and conducting quality checks on product. It also includes defuelling aircraft, completing post-defuelling operations and completing documentation.This unit addresses aviation technical skill requirements (physical, mental and task-management abilities) related to equipment and system operations of ground operations personnel and contributes to safe and effective performance in complex aviation operational environments.Operations are conducted as part of recreational, commercial and military aircraft activities across a variety of operational contexts within the Australian aviation industry.Work is performed independently or under limited supervision as a single operator or within a team environment.Licensing, legislative, regulatory or certification requirements are applicable to this unit. | ||
Duration and Setting | X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting. |
