What is the result of structural icing forming on aircraft surfaces?

When structural icing forms on aircraft surfaces, it leads to reduced performance and safety risks. Ice accumulation disrupts the smooth airflow over the wings and control surfaces, which can significantly diminish lift and increase drag. This change in aerodynamics can lead to a greater stall risk and can impair the aircraft's ability to maintain controlled flight. Additionally, icing can affect the operation of control surfaces, making it harder for pilots to maneuver the aircraft effectively.

The presence of ice on an aircraft can also lead to additional safety concerns, including longer takeoff and landing distances, as well as increased fuel consumption due to the altered aerodynamic performance. Therefore, recognizing and addressing the risks associated with structural icing is crucial for flight safety.
