Airservices Australia’s configuration of the integrated tower automation suite (INTAS) at Perth Airport had resulted in a situation where controllers performing some combined roles had the INTAS aural and visual alerts inhibited at their workstation. As a result, controllers performing such combined roles would not receive a stop bar violation alert or runway incursion alert at their workstation.
The ATSB is satisfied that the action taken by Airservices Australia addresses this safety issue.
Airservices Australia advised the ATSB that it raised a request for change to A-SMGCS alerting for the combined shift manager-surface movement controller-airways clearance delivery role in Perth INTAS Adaptation data settings on 24th June 2018, with the associated change implemented in the INTAS data release on 18th July 2018. As a result, when the combined role was selected, the relevant aural and visual alerts would no longer be inhibited.
