What icing condition category is reported when the accretion rate exceeds 3 inches per hour on the outer wing?

• A. Moderate Icing
• B. Severe Icing
• C. Light Icing
• D. Extreme Icing

Answer: (B)

Severe Icing is the correct category when the accretion rate exceeds 3 inches per hour on the outer wing. This classification indicates hazardous conditions for flight operations, as severe icing can lead to significant loss of aircraft performance, increased weight, and potential control difficulties. In this case, the outer wing of an aircraft is particularly critical because it can directly affect lift and maneuverability. The threshold of 3 inches per hour signifies a severe and potentially dangerous accumulation of ice, requiring immediate attention and suitable operational adjustments by pilots and air traffic controllers. Understanding these icing categories helps ensure that aviation personnel can make informed decisions about safety and operational limits in winter weather conditions.
