On 747-400, inboard Kruger slats will retract when applying reverse during landing, to avoid the structure damage to the slats. This information is from a book about 747-400.
Leading edge slats on high-performance wings serve to enhance the aerodynamic properties of the wing, particularly at lower speeds and higher angles of attack. By increasing the wing's camber and delaying airflow separation, slats improve lift and stall characteristics, allowing for better control and maneuverability. This results in increased lift during takeoff and landing phases, as well as enhanced performance in various flight conditions. Overall, slats contribute to the aircraft's safety and efficiency by expanding the operational envelope of the wing.

Slats on a plane are aerodynamic devices attached to the leading edge of the wings. They extend and increase the wing's curvature, enhancing lift at lower speeds, particularly during takeoff and landing. By improving airflow over the wings, slats help prevent stalling and allow the aircraft to maintain better control during critical phases of flight.
Aileron - Turning Flaps - Slowing down - allow a/c to fly slower. Spoiler - Slowing down also Slats - leading edge devices to allow for flying slower speed.
They are the ailerons on the outboard aft, to control roll and bank, the flaps on inboard end to alter lift characteristics, and the slats on leading edge to allow the wing to operate at a higher angle of attack.
You want to measure from the edge of your particular frame to the other edge and subtract about 1/4" for margin. Slats should be 1x6 at a minimum, at one per linear foot. 1x4's are ok if they are all that is available, but you should make sure to use 8 or more.
A leading edge slat is an aerodynamic device located on the front edge of an aircraft wing, designed to improve its performance at low speeds and during takeoff and landing. By extending the wing's camber and increasing its surface area, slats enhance lift and delay airflow separation, allowing for better control and stability. They can be fixed or movable, and their deployment increases the wing's critical angle of attack, contributing to safer flight in critical phases.
Lift can be increased by curving the wing downward. Most aircraft have 'flaps' at the rear inner edge of the wing to achieve this. Some aircraft even have 'slats' at the front of the wing to increase lift even more. - If you google 'aircraft slats', you will see a great picture of slats and flaps on an Airbus A310
Leading Edge Group was created in 1986.
Flaps are mounted on the aft or trailing edge of wings. When extended, they change the aerodynamic shape of the wing to produce greater lift at slower speeds. Slats are simply a flap on the leading edge of a wing rather than the trailing edge, increasing lift in a similar manner to a flap. The Slats actually allow the aircraft to obtain greater angle of attack. If too much Flaps are mounted on the trailing edge, this may want to cause the wing to pitch nose down. The Slats is a way to counter-act this force as it tends to cause the nose to pitch upwards. Because both the flap and slat offer great advantages in generating high lift, most aircraft today use a combination of both to maximize the lift coefficient as well as the maximum angle of attack while minimizing the effect of pitching moment.
Many of the bed frames we sell come with curved, sprung slats that reach half way across the frame (or all the way in the case of a single). These are fitted at either end into plastic cups with spurs on them, then tapped into purebred holes along the edge and down a central support rail. Another way this can be done is by aligning the slats in the frame whilst it is loosely assembled, and then tightening the frame, securing the slats tightly in place. The slats are always placed with the bow along the top. Hope this helps.
