A [[leading-edge slat]] is an [[aerodynamic]] surface running spanwise just ahead of the wing leading edge. It creates a [[leading edge slot]] between the slat and wing which directs air over the wing surface, helping to maintain smooth airflow at low speeds and high [[angle of attack|angles of attack]]. This delays the [[stall (flight)|stall]], allowing the aircraft to fly at a higher angle of attack. Slats may be made fixed, or retractable in normal flight to minimize [[drag (physics)#drag in aerodynamics|drag]].
