Plane Spotter: Air tractor

“Gallons per acre” isn’t a standard measure of aeronautical performance, unless a plane spotter is discussing one way owners use a highly specialized aircraft unmistakable for its ample width, tailwheel configuration, and impressive size. Whether the model you are inspecting is a radial-engine-powered AT-401, a turboprop AT-802, or any of the models in between, Air Tractors perform aerial application, fight fires, and even compete against unmanned aircraft systems for military assignments. The aircraft also makes a heck of a floatplane, as occasional sightings at summer aviation events have confirmed.
