Pest Control Aircraft Pilot Practice Test

What advantage does an electronic sprayer rate controller offer?

1. It enables manual adjustment of spray outputs

2. It reduces or increases the spray output as airspeed changes

3. It maintains a constant output regardless of conditions

4. It eliminates the need for calibration

The correct answer is: It reduces or increases the spray output as airspeed changes

The advantage of an electronic sprayer rate controller lies in its ability to automatically adjust the spray output based on changes in airspeed. When an aircraft's speed varies during flight, maintaining consistent pesticide application rates is crucial for effective pest control. The electronic sprayer rate controller responds to these speed changes and modulates the amount of pesticide being sprayed, ensuring that the application rate remains consistent across different flight conditions. This feature enhances the accuracy of pesticide application, reducing the risk of under- or over-application, which can lead to ineffective pest control or environmental harm. In contrast, manual adjustment of spray outputs requires human intervention and may not respond as quickly or accurately to changes in flight conditions. Maintaining a constant output regardless of conditions is beneficial but not as precise for varying airspeeds, as environmental factors can still impact application rates. While some electronic systems may reduce the frequency of required calibrations, they do not entirely eliminate the need for calibration to ensure optimal performance and accuracy.
