Controllers were routinely exposed to ‘not concerned’ radar tracks that were generally inconsequential in the en route environment, leading to a high level of expectancy that such tracks were not relevant for aircraft separation purposes. Training did not emphasise the importance of scanning ‘not concerned’ radar tracks in jurisdiction airspace.
The ATSB is satisfied that the safety action, when fully implemented, will reduce the risk associated with this safety issue.
In response to the occurrence, Airservices has amended its air traffic controller Abinitio training exercises to include ‘not concerned’ (black) track scenarios to ensure that training emphasised the importance of scanning ‘not concerned’ radar tracks. The scenarios will also be included in operational simulation training where appropriate.
Furthermore, Airservices advises that the safety issue (AO-2012-132-SI-01) will be used to raise awareness of black tracks amongst air traffic control staff.
