Response Text

As a result of issues previously identified by Airservices
Australia just prior to this recommendation, a number of systemic
controls were introduced to ensure that controllers are aware of
the importance of the separation assurance provisions of MATS
4.1.1.4. These measures included amendment to MATS 4.1.1.4 to
reflect the full intent of Separation Assurance, the development
and delivery of a refresher training module on separation
assurance, and the inclusion of separation assurance criteria in
Performance Assessment Reports. There is no recent evidence of the
existence of an ongoing systemic issue.
