The Autumn idea is a good one. Controlled burns with an aerial water bombing loitering over head should the situation get out of control
The aircraft could set up containment lines using retardant. This would provide currency and training for both flight and ground crews.
One problem is that the RFS/CFA are a volunteer organisation and may only be able to do hazard reduction at weekends. This could mean a need for full time hazard reduction teams.
Would aircrew be full time or volunteer?
Next question, are there any large waterbombers available for sale anywhere?.
Looking at the fleet, it appears that the airframes are converted by the end user.
The first lot of Viking CL-515 are goig to Indonesia in 2025. Long wait!!
