Icing condition is best described as which?

Icing condition is best described as which?

• A. A condition which prevents icing.
• B. A condition which will allow icing to occur on the aircraft, which can occur with OAT as much as +10 C and visible moisture.
• C. Icing is only possible in freezing rain.
• D. Icing cannot occur below 0 C.

Answer: (B)

Icing occurs when there is visible moisture in the air and the droplets are supercooled enough to freeze on contact with the aircraft’s surfaces. This can happen even if the outside air temperature is above freezing, up to around +10 C in some conditions, depending on droplet size and environment. That means icing is a condition that will allow ice to form on the aircraft when visible moisture is present, not a condition that prevents it. So the best description is a state that enables icing to occur, which can happen with outside air temperatures up to about +10 C alongside visible moisture. Icing doesn’t require freezing rain only, and it can occur below 0 C as well, so the other statements aren’t accurate.
