Airservices is Australia's air navigation service provider - we provide air traffic control, aviation rescue and fire fighting and air navigation services.

Short term noise monitoring

Airservices manages a short-term noise monitoring program which is an important addition to the Noise and Flight Path Monitoring System (NFPMS). Portable noise monitors can be deployed for a limited period of time, typically three months. They allow data to be obtained from locations that do not require or where a long-term monitor cannot be installed.

The results can be used to:

  • Quantify the impacts of a procedural change
  • To assess a site for suitability as a permanent site
  • Refine Airservices noise modelling activities.

A summary of data collected through the short-term noise monitoring program is below.

Limitations of Airservices Noise and Flight Path Monitoring System (NFPMS) data at General Aviation (GA) airports, including Archerfield, Jandakot, Moorabbin and Parafield airports

Airservices NFPMS was originally set up to monitor operations at major airports across Australia and relies upon obtaining the details of aircraft operations from lodged flight plans.

Over time, the NFPMS has expanded to include other airports in Australia’s main cities, within 50km of the main airport. However, the source radar data for these cities is still obtained from the main city airport, which can result in data gaps (depending on the distance of the secondary airport from the main airport). As these data gaps occur randomly throughout the day, the data, while incomplete, still provides a representative picture of the weekly, hourly and day/night distribution of aircraft operations.

General Aviation (GA) airports, such as Archerfield, Jandakot, Moorabbin and Parafield, have a high proportion of operations relating to training and GA. As a result, the majority of movements at these airports do not lodge a detailed flight plan and therefore there is limited aircraft identification data captured in the NFPMS. Aircraft operations at GA airports include higher numbers of small aircraft operating in closer proximity, compared to operations at major airports. These types of operations, combined with gaps in radar data and limited flight plan information, are all factors that impact the accuracy of the flight identification process in Airservices NFPMS.
