What type of angle is associated with the dihedral setup of a wing?

The dihedral angle is a specific type of angle that is critical in the context of aircraft wings and their design. It refers to the upward angle of the wings relative to the horizontal plane when viewed from the front. This angle plays a significant role in the aerodynamic stability of an aircraft. By having wings set at a dihedral angle, the aircraft is able to self-right during roll maneuvers, enhancing its stability during flight.

Understanding the dihedral angle is essential for practitioners in assembly and rigging because it directly affects how the wings interact with airflow and influence the aircraft's behavior during maneuvers. This differs from other angles like incidence angle, which is the angle between the wing's chord line and the aircraft reference line, or horizontal and vertical angles, which refer to different axes and are not specifically tied to the setup of wing geometry in an aerodynamic context.
