Which type of conditions might affect an aerial applicator's performance?

The performance of aerial applicators can be significantly affected by both high temperatures and high levels of stress, making this the correct choice. High temperatures can impact the equipment's operation and the efficacy of the chemicals being applied. For instance, if temperatures are excessive, the volatility of certain pesticides may increase, potentially leading to greater drift and reduced effectiveness on the target area. Furthermore, extreme heat can also affect the physical capabilities and endurance of the applicators, potentially leading to quicker fatigue.

Additionally, high levels of stress can impair decision-making and reaction times for an aerial applicator. Stress may arise from various sources such as workload demands, equipment malfunctions, or challenging weather conditions. When an operator is under stress, their ability to perform precise flying maneuvers and make quick adjustments may be compromised, increasing the risk for both application errors and safety incidents.

Therefore, recognizing the impact of both environmental factors and personal well-being is crucial for maintaining optimal performance in aerial application tasks.
