Pest Control Aircraft Pilot Practice Test

What occurs when spray contacts a structural part of the aircraft during application?

1. It evaporates immediately

2. It creates mist

3. It collects and falls off in large drops

4. It enhances the spray pattern

The correct answer is: It collects and falls off in large drops

When spray contacts a structural part of the aircraft during application, it collects and falls off in large drops. This phenomenon occurs because, upon hitting a surface, the liquid spray does not immediately evaporate or disperse into mist but instead coalesces into larger droplets. These larger droplets can then detach from the surface due to gravity or airflow, leading to potential runoff. This behavior is significant for pilots to understand, as it can affect both the efficacy of the application and the potential for overspray. Ensuring that spray does not unintentionally land on structural parts of the aircraft or affect flight safety is critical. In aerial pest control, managing how spray interacts with the aircraft helps prevent contamination or equipment malfunction and enhances precision in targeting the intended areas.
