ππ₯ Did You Know β¦ About Pre-Determined Dispatch (PDD) of Aircraft? π₯π
During the fire season, every second counts β especially when it comes to aerial firefighting. Thatβs where Pre-Determined Dispatch (PDD) comes in, dispatching aircraft at the same time as ground crews.
π What is PDD?
PDD is a system that allows helicopters and fixed-wing aircraft to be pre-assigned to locations based on forecast fire risk and conditions. On days of higher risk, the whole state is covered by PDD, ensuring aircraft are ready wherever they might be needed.
PDD enables the rapid deployment of aerial firefighting assets to high-risk areas on days of high fire danger. This means that on those days, aircraft are pre-assigned to specific response areas and are paged to incidents at the same time as fire trucks, enabling immediate initial attack on fires to help keep them small.
π¨ Where it came from:
PDD was developed under the Enhanced Aircraft Request and Dispatch System Project, initiated as part of the response to the Victorian Bushfires Royal Commission (VBRC) Recommendation 20.
That recommendation called for βa system that enables the dispatch of aircraft to fires in high-risk areas without requiring a request from an Incident Controller or the State Duty Officer.β
β± How it works:
When weather and fire danger reach certain levels, aircraft are dispatched at the same time as fire trucks and ground crews β if available and not already committed to another fire. In some areas, they may even arrive before trucks, as access can be challenging in remote or rugged terrain.
π Working with EMV & FFMV:
PDD operates in conjunction with EMV/VicEmergency, Forest Fire Management Victoria (FFMV) and other emergency partners, ensuring aircraft are strategically deployed where theyβre needed most to support crews on the ground.
π Why it matters:
π₯ Fires can spread rapidly β sometimes in minutes.
π PDD ensures aircraft are already in position, ready to respond.
β±οΈ It reduces response times, giving firefighters critical aerial support faster β helping keep fires small.
Next time you see a helicopter in the sky during fire season, remember β it might just be part of a carefully planned PDD mission, helping protect lives, property, and the environment.
