To70 and AerLabs support Western Sydney Airport environmental impact assessment by developing flight track website

On 27th June 2023, the initial flight tracks for the new Western Sydney Airport were unveiled through a user-friendly interactive noise tool developed by To70 in partnership with AerLabs, on behalf of the Department of Infrastructure, Transport, Regional Development, Communications and the Arts (DITRDCA). The noise tool allows residents to enter their addresses and visualise the extent to which their homes will be affected by aircraft noise disruptions.

The website provides a detailed display of the projected flight paths and their effects on nearby communities, aiming to foster community involvement in the Environmental Impact Assessment. Through clear communication of complex technical data and its implications for the local environment, the website encourages dialogue among the airport, government, and surrounding communities. To illustrate the situation effectively, it utilises maps and videos, linking the broader context to the specific impact in each location.

In the first 24 hours the website was visited over 150,000 times and the visualisations watched more than 65,000 times.

Rob Morris, Senior Aviation Consultant, To70 Australia Aircraft noise is experienced in very different ways, so we designed the tool to visualise flight path and noise impacts in a way which made it simple for people to understand the effect of airspace changes on them. We believe this is a great example of collaboration between To70 offices and our partners to leverage the depth and breadth of To70’s global experience pool and provide truly innovative solutions to our clients.”

Senior Aviation Consultant, To70 Europe, Maarten Tielrooij, emphasises: “These developments are an example of how we try to make the complex concept of aviation noise understandable to those who are most affected by it ”.

Founder and CEO of AerLabs, Robert Koster, remarks:  “Our mission is to reduce the environmental footprint of aviation with advanced tools that promote transparent and effective collaboration. With this capability, we are bringing a new level of value to stakeholder engagement by providing interactive access to the future flight paths and expected noise impact data.”.
