What four factors should be measured once the aircraft is set up for application?

The focus on tank capacity, application airspeed, flow volume, and effective spray swath width is crucial for ensuring a successful and efficient aerial application.

Tank capacity is essential as it determines how much pesticide can be carried for the application without the need for frequent refilling, which can be a significant logistical consideration during a spray mission. Application airspeed is equally important since it affects the dispersion pattern of the spray; too fast might result in drift, while too slow could lead to uneven application.

Flow volume is a measure of how much pesticide is being released per unit time, which needs to be aligned with the aircraft's airspeed to achieve the desired application rate. Finally, effective spray swath width refers to the area that the spray effectively covers and is vital for ensuring that the intended target area receives the appropriate application without overlaps or missed spots. This combination of factors allows for optimizing the aerial application process, improving efficacy, and minimizing environmental impact.

In contrast, other options include factors that are either less relevant to the immediate setup for application or do not directly impact the efficiency of the aerial application process in the same way. For example, temperature, humidity, and wind speed, while important for understanding environmental conditions, typically relate to timing and day
