Which of the following describes the effect of supercooled large drops on aircraft?

Supercooled large drops (SLDs) are liquid water droplets that remain in a liquid state even though they are below freezing temperature. When these droplets come into contact with an aircraft, they can freeze rapidly upon impact, leading to the formation of ice on the aircraft's surfaces. This ice accumulation can occur almost immediately, often before pilots or anti-icing systems can respond effectively.

The rapid formation of ice from supercooled drops can significantly impair the aerodynamics of the aircraft. Ice accumulation on wings and control surfaces can change the shape of these surfaces, increasing drag and disrupting airflow, which can compromise lift and overall aircraft performance. Therefore, understanding the effect of SLDs is crucial for ensuring safe and efficient flight operations.
