What characterizes trace icing intensity?

Trace icing intensity is characterized by minimal ice accumulation on aircraft surfaces due to very light icing conditions. This level of icing typically poses little or no serious risk to flight safety, allowing pilots and operators to manage the situation without immediate concern for significant impact on aircraft performance.

In environments with trace icing, the conditions may allow flights to continue without the need for de-icing equipment or preemptive measures typically required for more severe icing conditions. This contrasts with the other options, which describe greater levels of ice accumulation that would require more significant responses, such as the need for de-icing procedures or equipment, indicating a higher level of risk for operational safety.
