What is the function of slats on an aircraft wing?

Slats are designed to enhance the aerodynamic performance of an aircraft at high angles of attack, particularly during takeoff and landing phases. They help improve the airflow over the wing, thereby increasing lift by delaying airflow separation. This is critical for maintaining control and preventing stalling, which can be particularly challenging at low speeds.

The primary function of slats is to increase lift by modifying the wing's shape and changing the airflow characteristics. In this context, their role in creating additional lift directly counters the assertion that their main function relates to lateral control. While lateral control is essential for flight stability and maneuverability, slats are not directly responsible for this aspect. Instead, they primarily facilitate better lift characteristics and enhance the wing's overall performance, especially when flying at lower speeds.
