Near-north Ontario, French River | I've never witnessed a fixed wind duster but rotary wing (Helos) are used quite often I the area, not so much for crop dusting as for applying white wash to greenhouses. A help flying 15-20 above a 50ac greenhouse complex is pretty impressive as well. Circling the field once at 750 wouldn't serve so much as a survey of the field as it would alert others in the area that a duster is working. I only picked 750ft because it offers a buffer between the duster and any drones. Drop it to 500 if you like, I was only throwing the number out there. The point is to add a safety margin. |
