Action description

In response to this safety issue, Airservices Australia advised the following proactive safety action:

  • A temporary local instruction was issued to Melbourne air traffic controllers that introduced a runway change coordination checklist. The checklist is intended to provide a recordable process for implementing and coordinating runway changes. This checklist has since been incorporated into the Melbourne and Canberra Terminal Control Unit local instructions.
  • A temporary local instruction was issued to Melbourne air traffic controllers introducing a runway configuration coordination prompt. This prompt requires the Melbourne Tower Coordinator to remove the text ‘COORDINATE WITH MPL [Melbourne Planner] AND EN [Essendon]’ when preparing the digital automatic terminal information service, thereby prompting the Melbourne Tower Coordinator to conduct the required coordination. In addition a pop‑up memory prompt is being developed that will amend this temporary procedure.
  • Any update to the Melbourne Airport automatic terminal information service is automatically displayed in the message queue in the Essendon Tower cabin. This system change is intended to increase Essendon air traffic controllers’ situation awareness and to provide them with early opportunities to detect breakdowns in communication between them and Melbourne Airport air traffic controllers.
