Severe Drag Penalties

3D Wireframe Aircraft showing Drag Force and Flow Separation
Surface Effect
Friction Coefficient Spike:

Ice texture massively increases surface friction across the upper wing.

Aerodynamic Effect
Pressure Drag:

The altered wing profile creates a low-pressure wake that physically drags the aircraft backward.

Performance Effect
Deficient Acceleration:

High drag restricts the aircraft's ability to accelerate to rotation speed (VR) before runway end.
