What weather conditions should a Remote Pilot consider before flight?

A Remote Pilot should prioritize visibility, wind, and precipitation as essential weather conditions to assess before flight. Visibility is crucial because it directly impacts the pilot's ability to see and navigate the UAS safely, avoiding obstacles and ensuring compliance with regulatory requirements. Wind conditions are equally vital, as high winds can affect the stability and control of the drone, especially during takeoff and landing. Additionally, understanding precipitation is important because rain or snow can impact the drone’s performance and can pose safety hazards due to reduced visibility and potential water damage to the UAS systems.

While temperature and humidity are relevant weather factors, they are generally of secondary importance compared to visibility, wind, and precipitation when considering immediate safety and operational performance during a flight. Similarly, while pressure fronts and storm patterns are significant in long-term weather forecasting, they may not provide the immediate understanding required for a pre-flight assessment. Thunderstorm activity is critical to acknowledge, but it is typically assessed in conjunction with visibility and precipitation rather than as a standalone focus. Therefore, option B encompasses the most pertinent factors for ensuring a safe flight operation.
