Hate to revive an older thread, but.........
le Pingouin and CaptainMidnight have both made statement in this thread to the effect that IFR traffic information service is a 'workload permitting' scenario. Acknowledged that its a rare occurrence. Not withstanding the information in the AIP, the Australian Airspace Policy Statement as released today contains a note in part 17 "North of 65°S IFR flights are considered to have on ongoing flight information request and receive traffic information on other IFR flights and known VFR flights."
It sounds like the Departments expectations for a traffic information service differ from the expectations published in the AIP. It reads to me that the Dept expects that IFR flights can expect flight information and traffic information, workload is a not a consideration.
