How does frost on the wings of an airplane affect takeoff performance?

Frost on the wings of an airplane disrupts the smooth flow of air over the wing, significantly affecting the aircraft's performance during takeoff. When frost accumulates on the leading edges and upper surfaces of the wings, it creates an uneven, rough surface that can cause airflow separation. This disruption can lead to an increase in drag and a decrease in lift produced by the wings.

A smooth, uninterrupted airflow is critical for maintaining lift and achieving optimal aerodynamic efficiency. Frost alters this airflow, resulting in a potential loss of lift at lower speeds, which is particularly critical during takeoff when the aircraft needs to generate enough lift to become airborne. This situation emphasizes the importance of ensuring that wings are free of frost and ice to maintain safe operational performance.
