Name two weather factors that can significantly affect flight safety.

• A. Clear skies and low wind.
• B. Thunderstorms and icing.
• C. High humidity and fog.
• D. Low barometric pressure and solar flares.

Answer: (B)

Weather hazards that most threaten flight safety include thunderstorms and icing. Thunderstorms bring strong updrafts and downdrafts, wind shear, hail, heavy rain, lightning, and rapid changes in visibility and airspeed. These factors can cause abrupt control responses, dangerous turbulence, and even loss of aircraft control if encountered, so pilots plan around and avoid them whenever possible. Icing occurs when supercooled water droplets freeze on exposed surfaces in clouds or precipitation, creating a rough, growing ice layer. This reduces lift, increases stall speed, and degrades control effectiveness and engine performance. Even small amounts of icing can quickly deteriorate performance and handling, making continued flight riskier. The other options describe conditions that are either generally favorable or less consistently hazardous as direct weather threats. Thunderstorms and icing are recognized as two of the most significant weather-related safety risks in aviation, which is why they’re highlighted as critical factors to consider.
