How does icing impact aircraft performance?

Icing significantly impacts aircraft performance by increasing drag and weight while reducing lift. When ice forms on the wings and other critical surfaces, it alters the smooth airflow over the aircraft. This disruption leads to an increase in drag, making the aircraft less aerodynamic and requiring more power to maintain speed. The additional weight from the ice also affects the aircraft's overall performance, particularly during takeoff and landing phases, where weight management is crucial for safe operation.

Moreover, the presence of ice on the wings disrupts the airfoil's shape, which is essential for generating lift. The loss of lift can lead to reduced climb performance and, in extreme cases, could contribute to stalls if the aircraft is not managed correctly.

While some incorrect options suggest benefits or minimal impact related to lift and drag, the reality is that icing presents a significant challenge that must be managed through proper de-icing and anti-icing measures to ensure safe flight operations.
