The induced angle of attack () is an aerodynamic term used to describe the effective angle of attack experienced by a wing or lifting body due to the presence of downwash from its own circulation. When an airfoil or wing generates lift, it creates a circulation around its surface, which leads to a downward deflection of the airstream behind the wing, known as downwash.
- is the induced angle of attack,
- is the downwash velocity at a specific point behind the wing,
- is the freestream velocity (constant velocity far away from the wing).
