What should a remote pilot consider regarding weather conditions?

The correct choice highlights critical factors that directly impact the operation of a drone. Wind speed is essential because high winds can significantly affect the stability and control of the aircraft, making it difficult to maintain desired flight paths and increasing the risk of accidents. Visibility is another crucial element; poor visibility due to fog, rain, or other conditions can hinder the pilot's ability to see obstacles, both on the ground and in the air, leading to potential collisions. Precipitation, such as rain or snow, can affect the drone's performance and safety, as it may interfere with sensors or cause water damage.

While other choices contain relevant weather factors, they do not encompass the most direct impacts on remote piloting activities. For example, temperature and humidity are vital for understanding performance, yet they do not have the immediate effect on drone control that wind speed, visibility, and precipitation possess. Similarly, while altitude and terrain are important to pilot planning, they are not inherently weather conditions. Wind direction, sunlight, and air quality can be important in specific contexts but are secondary to the more immediate concerns presented in the correct answer.
