Unlike that of an airplane, the WSC angle of incidence has a significant change in flight because the carriage is attached to the wing, which allows the wing to rotate around the carriage hang point on the wing and is controlled by the pilot as shown in Figure 2-7. 

 Pitch angle is the angle the WSC wing root chord (center of wing) makes with the Earth’s horizontal plane. Many pilots confuse the pitch angle, which is easily seen and felt, with the angle of attack (AOA) which is not as perceptible. For example, if flying in a glide with the engine idle and the nose lowered, the pitch angle can be below the horizon. Another example would be flying at full power climb with the nose raised, resulting in the pitch angle being well above the horizon. [Figure 2-8] Pitch angles are covered in greater detail in chapter 6. 

 Deck angle is the angle of the cart’s wheel axles to the landing surfaces, as in the powered parachute (PPC) deck angle. Relative wind is the direction of the airflow with respect to the wing; it is parallel to and opposite the WSC fl ightpath. Relative wind may be affected by movement of the WSC through the air, as well as by all forms of unstable, disturbed air such as wind shear, thermals, and turbulence. When a
