What is the recommended distance to maintain from thunderstorms during operations?

Maintaining a distance of 20 nautical miles from thunderstorms during operations is recommended due to the significant hazards posed by thunderstorm activity. This distance allows for a safety buffer that helps pilots avoid severe turbulence, lightning strikes, hail, and strong updrafts and downdrafts associated with thunderstorms. These phenomena can affect the stability and control of unmanned aircraft, making it crucial to operate well outside the storm's influence.

In addition, thunderstorms can produce rapidly changing weather conditions that can lead to dangerous flight situations. The 20 nautical mile guideline is rooted in safety practices established by aviation authorities, emphasizing the need to respect the unpredictable nature of thunderstorms to ensure the safety of both the aircraft and surrounding environments. This practice helps ensure that operators can react to any unexpected weather changes without compromising safety.
