The primary purpose of wing slats is to increase lift. Wing slats are aerodynamic devices located on the leading edge of an aircraft's wing. When deployed, they can alter the airflow over the wing, allowing it to maintain lift at lower speeds and higher angles of attack. This helps to enhance the wing's performance during critical phases of flight, such as takeoff and landing, where maintaining sufficient lift is crucial.

By increasing the lift produced by the wings, slats effectively increase the aircraft's stall margin, which can lower the stalling speed. However, their main function remains to augment lift rather than solely focusing on reducing stalling speed. While a reduction in stalling speed is a beneficial outcome, it is the increase in lift that is the fundamental reason for their design and usage in aviation.
