Under what weather condition should a pilot refrain from operating an RPAS?

Heavy rain and thunderstorms present significant hazards for operating a Remotely Piloted Aircraft System (RPAS). These conditions can lead to reduced visibility, making it difficult to control the drone and assess its surroundings. Additionally, thunderstorms are often associated with strong winds, turbulence, and lightning, all of which pose risks not only to the drone’s operation but also to safety. Operating in such adverse weather can result in equipment failure, loss of control, and potential accidents, which is why it is critical for pilots to refrain from flying under these circumstances.

In contrast, clear skies with no wind, cloudy conditions, and sunny weather with lower temperatures are generally considered acceptable for RPAS operations, assuming other regulatory and safety requirements are met. These conditions generally provide better visibility and more stable flying environments.
