Identify key weather factors that impact UAS flights and how you should respond.

• A. Only wind is important
• B. Weather has no impact
• C. Only humidity matters
• D. Wind speed/gusts, rain/snow, temperature, visibility; check METAR/forecasts, avoid operations in adverse conditions, and adjust limits and mission plan accordingly.

Answer: (C)

Weather affects UAS flights in multiple ways, so you must consider several factors and plan accordingly. Wind speed and gusts influence stability, control authority, and battery use; precipitation such as rain or snow can impair sensors and electronics, reduce visibility, and even affect propulsion or cause icing in some conditions; temperature changes air density and battery performance, which can alter lift, range, and efficiency; visibility determines whether you can safely see and avoid obstacles and stay within any required line-of-sight limits. Because conditions can shift quickly, check current and forecast weather for the operation area (METARs and forecasts), and if conditions are adverse or outside your aircraft and mission limits, avoid flying or adjust the plan. That often means lowering altitude, reducing speed or payload, or building in additional safety margins and contingency plans. Humidity alone doesn’t capture the full range of weather effects on a flight.
