Unit Descriptor

Unit Descriptor 

This unit involves the skills and knowledge required to control a helicopter on the ground, including starting and stopping a helicopter engine, engaging the rotor and controlling the main rotor disc and anti-torque system, fulfilling all required safety requirements, performing pre-taxi functions and manoeuvring the helicopter on the ground. Licensing, legislative, regulatory or certification requirements are applicable to this unit.

Application of the Unit

Application of the Unit 

Work must be carried out in compliance with the relevant licence and aircraft rating requirements of the Civil Aviation Safety Authority (CASA) and/or ADF; airspace control requirements and Day Visual Flight Rules (Day VFR); and aircraft control principles, regulations, safety codes, protocols and procedures relating to controlling a helicopter on the ground.

Use for ADF Aviation is to be in accordance with relevant Defence Orders and Instructions and applicable CASA compliance.

Operations are conducted as part of commercial or military aircraft activities across a variety of operational contexts within the Australian aviation industry.

Work is performed under limited supervision.

This unit is nominally packaged at Certificate IV.
