Package 4 investigations and options

Airservices Australia is pleased to release the findings of Package 4 investigations into safe and practical ways to use Brisbane airspace differently to better manage aircraft noise.

Package 4 is the final package of work through the Noise Action Plan for Brisbane. Investigations for this work were undertaken by Trax International (Trax), an airspace and air traffic management consultancy. Trax researched a range of concepts to minimise the impacts of aircraft noise by using the Brisbane airspace system differently and identified potentially feasible options for Airservices’ consideration.

We have prepared a summary of the full technical report prepared by Trax. It has four sections:

  1. Package 4 summary: an introduction to Package 4 and a brief summary of investigations and findings.

  1. Options progressed for community feedback: there are five proposals for community review and feedback – two respite options and changes to three arrival paths.

  1. Wider South East Queensland airspace system review: a description of the airspace system, how it works, and what this means for potential changes to Brisbane Airport operations.

  1. All concepts investigated: in addition to the five proposals put forward for community feedback, several other concepts were investigated. All concepts are described and findings summarised in this section.

The complete Package 4 Report prepared by Trax is also available for review. Please note, this is a lengthy and complex technical report written for Airservices. Airservices has prepared the summary of this report to provide a more accessible explanation of the investigations and findings.

The options being engaged on have been added to the Brisbane Baseline Model so they can be viewed in greater detail, including using the address search function and being able to zoom in to see the suburbs relevant to each option.
