Unit Descriptor

Unit Descriptor 

This unit provides the knowledge and an inventory of skills to provide air traffic control in airspaces within terminal areas. Licensing, legislative, regulatory or certification requirements are applicable to this unit.

Application of the Unit

Application of the Unit 

This unit is applied to specific terminal airspaces that offer varying levels of air traffic services according to the ICAO and national classifications of airspaces. The defining features of approach control are the safe release of aircraft on departure and the safe termination of flight for landing.

Persons exercising competence in this unit will need to fulfil the licensing and regulatory requirements of the Civil Aviation Safety Authority pertaining to air traffic controllers.

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

Work is performed under various levels of supervision dependent on workplace context, and might be in a team environment.

Work involves applying separation standards. It assesses the controller s ability to apply the full range of separation standards or provide traffic advice in situations involving medium to high levels of traffic volume and complexity and in adverse weather conditions.

This unit of competency is packaged at Diploma level.
