Aircraft target the highest-intensity head cells of the assigned fire. LAT/VLAT lay retardant lines (~60 min effect); SEAT and rotary drop water (~30 min suppression). State machine: outbound 40% → drop → return 30% → reload 30% of turnaround time. Ground crews build containment line at Report 56 rates on the fire perimeter, 24/7. Aircraft are stood down outside 06:00–20:30, when FFDI > 100, or when wind exceeds the per-type gust limit (SEAT 45, LAT 55, VLAT 65, Rotary Med 50, Rotary Heavy 55 km/h). Dozers/tankers can't operate on slopes steeper than their working limit (D4 18°, D6 25°, Tanker 15°, Handcrew 35°).

Lesson
Victorian Bushfire Trainer
Collard Bushfire and Environmental · Interactive 3D fire spread simulator
Built for training: explore how fuel, weather, topography, and suppression decisions interact
in a bushfire. 4.8 km × 4.8 km of Victorian foothill country — eucalypt forests in
the gullies, dry sclerophyll on the ridges, grass in the valley flats. Fire spread uses the
McArthur Mk5 Forest Fire Danger Meter with Noble slope correction, plus wind-driven ember
spotting under severe conditions and a diurnal FFDI cycle.
Start with a scenario preset on the right, then click anywhere on the terrain to ignite.
Try painting hazard-reduction zones before ignition to see how fuel management
changes the outcome. Once a fire is running, switch tools to place containment lines
or water drops. Hover any cell for details.
For a structured experience, try the Lessons button — scripted scenarios with goals
like "contain the fire to under 200 ha" or "save the township from the SW wind change".
Training Lessons
Each lesson sets a scenario and a goal. Reset to try again.
L1 — Slope rules
Ignite at the base of a slope on an average day. Observe spread upslope vs across.
Goal: keep the fire below 50 ha for 2 hours using one containment line.
L2 — Fuel reduction
Identical severe weather: try once with no preparation, once with hazard-reduction
burns around a township. Compare area burnt at 4 hours.
L3 — Wind change
Black Saturday-like setup with a SW change at 17:30. The long eastern flank becomes
a new head fire. Goal: anticipate and pre-position the line.
L4 — Spotting under FFDI 100
Catastrophic conditions. Embers can launch new fires 2 km downwind. Goal: observe
how spotting defeats a single containment line.
L5 — Night vs day
Start at 22:00 with the same fire size and weather. Diurnal cooling slows spread —
when is the best window for direct attack?
L6 — Free play
No goals. Experiment with any combination. Use the view modes to understand fuel,
slope, and moisture distribution.
