During flight, what is the primary concern if ice builds up on the wings?

The primary concern when ice builds up on the wings during flight is increased drag and reduced lift. Ice accumulation disrupts the airflow over the wings, which is crucial for generating lift. As a result, the performance of the wings is significantly degraded, leading to a higher stall speed and potential loss of control. This makes it much harder for the aircraft to maintain altitude, increases the required power to achieve the same performance, and can also lead to unsafe flying conditions.

Improved fuel efficiency and enhanced stability do not apply in this scenario; in fact, ice formation has the opposite effect, as it can lead to higher fuel consumption and decreased aircraft handling qualities. Additionally, the notion that there would be no significant impact is inaccurate, as the risks associated with ice buildup are well-documented in aviation safety protocols. Therefore, the concern surrounding ice on the wings is fundamentally tied to its detrimental effects on drag and lift dynamics.
