 Follows the same principle as the ClAlphaBase attribute. Usually this value is negative and the airfoil creates a pitch down force when the angle of attack increases beyond the stall angle (stable). The aircraft will pitch down on its own and accelerate again. A positive value is destabilizing. Follows the same principle as the ClAlphaBase attribute.

 +> The lower the value of ''ClAlphaBase'' the more the nose will drop when approaching a stall. Values near ''-0.2'' tend to soften the stall behavior.
