Air traffic control is a highly safety-critical function of the aviation system, yet the process by which Airways ensured that workplace practices were in accordance with documented procedures was not effective, as shown by the non-compliance with written and agreed roster requirements.
The Commission believes this is a safety issue that the Director needs to address with Airways and recommends that Airways be required to implement an effective and auditable means of capturing the performance of individual controllers in a systematic way, as will be expected under the principles of safety management systems.
