Safety Recommendation

The Australian Transport Safety Bureau recommends that Airservices Australia conduct a review to determine why flight crews were able to submit flight plans and operate on non-standard routes in contravention of the AIP, which required crews to plan on routes provided to the air traffic control system by the publication of air route specifications.

Since the release of this report in 2003, Airservices has been investigating the issue of non standard routes and non standard levels in respect of recommendations R20030056 and R20030057.

As you would be aware, flight planning errors of this type are routinely and reliably tracked through the ESIR application. Airservices analysed this data and ascertained that non standard routes are not normally a significant contributory factor to Breakdown of Separation.

Nonetheless, over the past several years we have invested significantly in examining technical solutions that would detect flight planning errors and highlight them to the controller.

Our investigations determined that it was not feasible to use either NAIPS (Airservices' flight planning system) or to develop a separate database to process flight plans prior to entering the Eurocat system. Further, we determined that the cost of implementation in Eurocat for a warning system is high, and as Airservices has now commenced work on its future ATS system the lead time and cost does not support further work in this area... As demonstrated above, Airservices has seriously considered the issues raised in this report and has determined that there are no further reasonable steps that can be taken to address the recommendations.
