Which effect does ice accumulation have on stall characteristics?

• A. Increases stall angle
• B. Decreases stall speed
• C. Increases stall speed
• D. Has no effect on stall characteristics

Answer: (C)

Ice accumulation has a significant impact on the aerodynamic properties of an aircraft, particularly affecting its stall characteristics. When ice forms on the wings or control surfaces, it disrupts the smooth airflow that is crucial for maintaining lift. This disruption leads to an increase in stall speed, meaning that the aircraft will stall at a higher speed than it would without ice on its surfaces. The presence of ice alters the wing's shape and the associated lift-to-drag ratio. As ice accumulates, the wings become heavier and less efficient, requiring the aircraft to reach a higher airspeed to generate the same amount of lift that it would normally require in clean conditions. Given these changes in the aerodynamic performance caused by ice, it is clear why an increase in stall speed is the correct outcome of ice accumulation on an aircraft.
