AVIY5022B
Manage traffic flow

This unit involves the skills and knowledge required to work as part of a team and to conduct traffic sequencing and regulate traffic flow. This includes providing major delaying actions and minor flow adjustments to achieve the necessary spacing and order, and responding to changing conditions. Licensing, legislative, regulatory or certification requirements are applicable to this unit.

Application

This unit has application for air traffic control operators. In addition to separating airspace users, a safe, efficient and regular traffic flow is required to enable the effective use of aerodrome terminal facilities such as runways and taxiways.

Work must be carried out in compliance with the relevant air traffic services regulatory requirements of the Civil Aviation Safety Authority and national operating standards.

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 in a team environment.

Traffic flow is managed using automated systems or by manual determination. If automated systems are used, human reasoning should be applied to ensure safety and the most suitable flow of traffic particularly in times of adverse weather and/or emergency and abnormal flight operations.

The controller must demonstrate an ability to establish traffic sequences, regulate traffic flow, and regulate workload in situations involving medium to high levels of traffic volume and complexity, and in adverse weather.

This unit of competency is packaged at Diploma level.
