주익이나 기타 날개의 앞쪽 언저리에 부착된 움직이는 제어면이다. 저속에서 확장될시 향상된 제어를 제공한다. 고속에서 수축되어지고 날개의 전방면을 형성한다.

A movable control surface attached to the leading edge of a wing or other airfoil which, when extended, creates a slot to allow high-energy air to be introduced into the boundary layer over the top of the airfoil. It prevents stalls at high angles of attack and improves lateral control at lower than normal airspeeds. It is closed during normal flight and forms a profile of the airfoil. Excludes:leading edge devices for creating lift that are not slotted to duct air over the top of a wing or other airfoil. Excludes:FLAP, WING LANDING.
