Angle of attack (α) Calculator

The angle of attack (AOA) is the angle between the chord line of an airfoil and the relative wind. It is typically measured in degrees or radians. A positive angle of attack typically generates lift, while a negative angle of attack can result in a stall or increased drag. The formula for the angle of attack ($\alpha$) is:

Where:

• $\alpha$ is the angle of attack (in degrees or radians),
• $L$ is the lift force (in Newtons or pounds-force), and
• $D$ is the drag force (in Newtons or pounds-force).
