It’s all perfectly safe. Except for known unknowns.
CASA views the current use of contingency management practices as unsustainable and is actively engaging directly with Airservices Australia (AA) to assist them to address the underlying drivers so that they can deliver services to the expected level. Whilst the contingency practices used do provide an acceptable level of safety performance at the location level, the widespread regular use of contingency practices across the entire system may introduce additional risk which will need to be monitored. CASA intend to address the root cause of the issues raised, through a combination of surveillance (key focus areas), enforcement and direct consultation.
Less surveillance and consultation and more enforcement would be appreciated.
