An air duct outlet is disclosed herein. The air duct outlet includes a housing comprising a first wall being substantially planar and a second wall being at least partially convex to the first wall. The first wall and the second wall are disposed in adjacent, spaced-apart relation and defining at least two sides of an air passageway. The air passageway extends along a flow path between an inlet and a flared outlet. The air duct outlet also includes a vane pivotally disposed within the air passageway along the flow path. The vane is movable between a first position wherein the vane substantially blocks the air passageway and a range of other positions that are increasingly substantially parallel to the first wall. An air stream flowing through the air passageway is deflected by the vane an amount that decreases with each position more remote of the first position over the range such that the air stream adheres to the second wall by an amount that increases with each position more remote of the first position over the range. Also, the air stream exits from the air duct outlet in a direction that is increasingly transverse to the first wall as the vane moves away from the first position.
