Which SCALP function is described as smoothing airflow over surfaces?

• A. Angle Of Incidence
• B. Pitch Rate
• C. Streamlines
• D. Lateral Sideslip

Answer: (C)

Streamlines visualize how air moves around surfaces, and when the lines are smooth and evenly spaced, they indicate airflow is being smoothed over the surface. In the SCALP context, this function represents the path air particles follow as they flow smoothly along the surface, reflecting a well-behaved, streamlined flow with minimal separation. The angle of incidence concerns how the flow meets the surface, not the smoothing of the flow; pitch rate and lateral sideslip describe the aircraft’s motion, not the airflow pattern over surfaces. So, the function that describes smoothing airflow over surfaces is streamlines.
