How can the volume of spray be adjusted in a rotary wing aircraft?

The volume of spray delivered by a rotary wing aircraft can be adjusted by changing the aircraft's speed. When the speed of the aircraft is increased, the spray pattern becomes narrower and denser, effectively increasing the volume of product applied per unit area as the aircraft moves over the target. Conversely, reducing the speed allows for a broader spray pattern, which can lead to a lower volume of product being applied per area due to the aircraft covering the same area more slowly.

Changing the altitude and nozzle type can influence factors such as droplet size and distribution but do not fundamentally change the overall volume of spray delivered over the target area in a consistent and controlled manner as speed does. Adjusting the fuel level would not directly affect the spray volume but could influence flight dynamics, potentially leading to inconsistent application if not managed properly.
