What should a pilot do if ice forms on the wings during flight?

When ice forms on the wings during flight, seeking a warmer atmosphere to melt the ice is the most effective action a pilot can take. Ice accumulation on the wings can significantly degrade lift and increase drag, leading to a loss of control and potentially hazardous flight conditions. By descending to a lower altitude, the pilot may enter a warmer environment where the ice can melt, restoring the wings' aerodynamic performance.

This approach allows the pilot to address the immediate danger of ice accumulation and regain control of the aircraft. Flying at the same altitude might keep the aircraft in conditions conducive to further ice growth, while using speed brakes could exacerbate the situation by increasing drag and potentially leading to a stall. Therefore, actively seeking a warmer atmosphere becomes the critical and most effective response to ice on the wings.
