Action description

In response to the draft report, Network Aviation advised that ATSB that:

Through a review conducted by representatives of the Qantas Groups Flight Operations Safety Committee (FOSC) and safety risk specialists in the business a threat line has been added to the Controlled Flight into Terrain (CFIT) Bowtie including both the non-precision and precision approach bowties. The threats and controls were reviewed based on the event and the learnings from that event. As a result, all CFIT bowties have been updated. We have added escalation factors and escalation factor controls to the Visual Reference control on bowtie 3.1. And we have added the “Flt Crew operate below the appropriate minimum altitude (i.e. lowest safe altitude, DA, MDA)” threat line in its entirety to bowties 3.2 and 3.3.
