The atomization and distribution of insecticide sprays produced from a Bell 205A-1 turbojet helicopter and spray system were evaluated under open ground conditions. The degree of atomization was within the same range as that produced by the smaller helicopters, and the acceptable swath width was wider. In some flights there were two very high deposit peaks with low deposit between those peaks, similar to that produced by a fixed-wing aircraft spraying at a low height above the ground. By visual observation, the main rotor vortexes appeared stronger and more pronounced than those of smaller helicopters.
