How can weather affect UAS operation?

• A. Weather affects only GPS accuracy.
• B. Weather affects visibility, wind, and battery performance; check conditions before flight.
• C. Weather never impacts flight.
• D. Weather affects only the drone's color.

Answer: (B)

Weather can impact UAS operation in several practical ways. Visibility affects your ability to see the drone and judge distances, which is crucial for maintaining safe line-of-sight and spatial awareness. Wind, including gusts, directly influences stability, control responsiveness, and energy use; strong winds can push the drone off course, shorten flight time, or make precise maneuvers more difficult. Battery performance is also tied to weather: cold temperatures can reduce capacity and flight time, while hot conditions can affect battery health and electronics. Because of these effects, checking current weather and forecasts before flight helps you decide whether to proceed, adjust the flight plan, or postpone. The other statements are not accurate because weather influences much more than GPS accuracy, it can impact flight itself, and it is not limited to affecting only the drone’s color.
