Safety issue description

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.

Proactive action

Action number: AO-2018-032-NSA-051
Action organisation: Airservices Australia
Date: 01 October 2020
Action status: Closed

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.
