A sensitivity analysis was run using three different aerial spray drift models. The combined analysis indicated that droplet size, downwind distance, wind speed and boom (flight) height were the four most important, drift related variables of the 10 studied. Two of these variables can be controlled directly by the applicator and the other two can be influenced via management decisions. Equipment and operating conditions are given for three specific droplet sizes when a pilot wants to use any of four aircraft speeds or four gallonages.
