Sydney: minor change to flight paths

Temporary flight path change in Sydney
Over the last two weeks residents of suburbs including Coogee, South Coogee, Randwick and Maroubra may have observed changes to the flight path. This is because the usual departure flight path has been temporarily suspended.

This situation has arisen due to a technical problem caused by a third party provider’s coding of flight path data into aircraft flight management systems. Airservices was notified of the issue by the airlines. Airservices is undertaking a comprehensive investigation into whether there are any safety implications and as a result, use of the flight path has temporarily been suspended.

Aircraft are currently being assigned individual headings by our air traffic controllers while the situation is being investigated. While these headings replicate the flight paths as closely as possible, an identical result cannot be achieved. As such, variance in the flight path that aircraft follow over these suburbs will continue until the issue is resolved.

Airservices is working with the third-party provider and airlines to identify and address the safety issues as quickly as possible to allow the flight path to be reinstated. It is expected this will not be completed until late November. There will be no other changes to noise sharing arrangements while this problem is investigated.

Airservices thanks you for your patience while this issue is resolved.

Correct. What this means is that aircraft on 34R are not permitted to fly the MARUB3 departure. Instead, aircraft are being given a radar heading of 070º on the SY1 departure and at 500ft we'll make that right turn so the track will vary day to day depending on the wind. We still apply NADP2 procedures though.

AviatorInsight, many thanks. For those (including me) who don't know, NADP2 is Noise Abatement Departure Procedure (version) 2. It is on Internet so I won't explain it: that's best left to our aviators.

Latest nav data cycle has now fixed the coding issue and we're back to now flying the MARUB departure on profile.

Departing Syd for Mel, QF411 on Friday, decent weather and visibility. Appreciated the different views from 4K. Tracked south over water, down the coast, for about 10 mins. Good gawk.
