Unit Descriptor

Unit Descriptor 

This unit involves the skills and knowledge required to maintain radio communications using English language as part of airport operations, including the operation, management and maintenance of radio equipment under normal and emergency conditions. It also covers the skills and knowledge needed when taking appropriate action in the event of radio failure, including maintenance of communications with aircraft using light signals. Required performance includes compliance with all relevant regulatory requirements (i.e. CAR Part 5 Div 3 and CAR 82-85 inclusive). 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.

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

Work is performed under limited supervision.

Work involves the application of aircraft radio communication principles, regulations, standard phraseology, safety codes, protocols and procedures to maintain radio communications with aircraft as part of commercial airport activities across a variety of operational contexts within the Australian aviation industry.
