Which SCALP function relates to angle between wing and airflow?

• A. Streamlines
• B. Angle Of Incidence
• C. Pitch Rate
• D. Collective Coupling

Answer: (B)

Understanding how the wing sits relative to the air is determined by the angle of incidence. This is the fixed angle between the wing’s chord line and the aircraft’s longitudinal axis, setting the baseline orientation of the wing in the air. In flight, the actual angle between the wing and the incoming airflow changes with speed and pitch, but the incidence angle is the geometric parameter that defines that starting relationship. Among the options, Angle Of Incidence best matches the concept of the wing’s orientation relative to the air considered in SCALP. Streamlines describe how air flows around the wing, not the wing’s mounting angle. Pitch rate is the speed of pitching motion about the aircraft’s axis, and collective coupling concerns rotor control interactions.
