Which terms are used to classify icing?

In aviation meteorology, icing classification is based on the intensity of ice accumulation on an aircraft during flight. The terms used to classify icing are designed to provide pilots and operational personnel with a clear understanding of potential hazards.

The correct classification relies on the specific characteristics of icing conditions. The terms "Trace," "Light," "Moderate," and "Severe" are standardized terms that describe the severity of icing conditions as follows:

• "Trace" indicates very light icing that does not pose a significant threat and may not require immediate action.

• "Light" icing represents a slightly more noticeable accumulation that could require some operational adjustments but is manageable without immediate concern.

• "Moderate" icing presents a more significant accumulation of ice, necessitating immediate and often decisive action by pilots to maintain safe operations.

• "Severe" icing is characterized by rapid ice accumulation that can severely affect aircraft performance and requires immediate corrective actions, potentially including changes in flight path or altitude.

Understanding these classifications is crucial for safe flight operations as pilots must assess and respond to icing conditions effectively. The other choices do not accurately reflect the standard terms used in the industry, making them less appropriate for this context.
