Simultaneous Opposite Direction Parallel Runway Operations (SODPROPS) Report
SODPROPS mode is prioritised for use where weather and traffic conditions allow.
The following conditions must be met:
- dry runway
- less than 5 knot tailwind
- cloud base not below 2,500 ft (762 metres)
- 8 km visibility
- low traffic levels.
The mode is most likely to be used during the following hours:
- 9pm to 6am six days a week
- 6am to 8am Saturday and Sunday mornings
- 12noon Saturday to 4pm Sunday.
Improving our reporting
Airservices Australia is committed to providing clear, accurate, and transparent reporting to the community. We began monthly reporting on SODPROPS use in June 2024 and have continued to review and refine the methodology used to prepare these reports.
We have updated the methodology used to report SODPROPS availability. These changes apply from the June 2026 report onwards and do not change how SODPROPS is operated or how SODPROPS flights are counted as a total percentage of flights at Brisbane Airport.
The updated methodology will include periods of unstable weather conditions, and times when forecasts indicate that SODPROPS conditions will not be available for at least 45 minutes, in the total time reported as “SODPROPS conditions not met during priority hours, due to weather conditions”. These situations have been reported separately to this point, but as they relate to the availability of the required weather conditions to operate SODPROPS, they will now be presented collectively. We are also expanding our reporting on “operational reasons” to better explain the constraints that can prevent the use of SODPROPS when weather conditions allow.
Additional SODPROPS use
Additional SODPROPS movements may be recorded when conditions were not available. This is primarily due to transition periods. These occur when SODPROPS is in operation and the system identifies that suitable conditions are no longer available but some aircraft will already be planned on SODPROPS flight paths. These flights will continue their departure or landing as planned, when safe to do so. This could be several minutes after the system notes SODPROPS conditions have ended.
These extra SODPROPS movements were captured in February 2025 reporting, and we have now updated the report structure to separate these extra movements from movements during available conditions. This will apply to reporting from February 2025 on. Previous months only captured SODPROPS movements during available hours and these reports will not be changed. The new structure reports on use and movements during available conditions on the left of the page and movements outside of these conditions on the right.
Rounding of hours
For simplicity, the reporting now uses whole hours rather than hours and minutes. Results of 30 minutes or more are rounded up to the next hour and less than 30 minutes are rounded down.
Note: On 1 December 2025, Brisbane Airport Corporation (BAC) commenced an 18 month trial to collect data on tailwind operations, continuing long term efforts to safely reduce overnight aircraft noise for local communities. When operational conditions permit, this voluntary, opt-in trial allows participating pilots to depart from the eastern runway (01R) in tailwind conditions between 5 to 10 knots during overnight hours (10pm to 6am). These movements are not included in our SODPROPS Usage report.
