What are slats on a wing?
Description. Slats are extendable, high lift devices on the leading edge of the wings of some fixed wing aircraft. Their purpose is to increase lift during low speed operations such as takeoff, initial climb, approach and landing. Slats are retracted in normal flight to minimize drag. Slats are high-lift devices typically used on aircraft intended to operate within a wide range of speeds.Thus, controlling the slats and flaps can be used to increase or decrease the area generating lift, which enables the pilot to control the speed. Slats and flaps are extended and retracted, and the spoilers are raised and lowered using suitable actuators.Description.
