The triple-slotted trailing edge flaps are well displayed and the Krueger flaps on the leading edge also are visible. In aircraft design and aerospace engineering , a high-lift device is a component or mechanism on an aircraft's wing that increases the amount of lift produced by the wing.
Slats, also known as leading edge devices, are extensions to the front of a wing for lift augmentation, and are intended to reduce the stalling speed by altering the airflow over the wing. Slats may be fixed or retractable - fixed slats (e.g. as on the Fieseler Fi 156 Storch ) give excellent slow speed and STOL capabilities, but compromise ...
Many high-performance aircraft use the dogtooth design, which induces a vortex over the wing to control boundary layer spanwise extension, increasing lift and improving resistance to stall. Some of the best-known uses of the dogtooth are in the stabilizer of the F-15 Eagle and the wings of the F-4 Phantom II , F/A-18 Super Hornet , CF-105 Arrow ...
Double delta wing aircraft (Concorde, Tupolev Tu-144, Boeing 2707 and Lockheed L-2000 SST projects) featured a forward extended leading edge that may be considered as a wing strake; it provides the same additional vortex lift at high angle of attack by leading edge suction.
A circulation control wing (CCW) is a form of high-lift device for use on the main wing of an aircraft to increase the maximum lift coefficient and reduce the stalling speed. CCW technology has been in the research and development phase for over sixty years. Blown flaps were an early example of CCW. [1]

Droop flaps function with other high-lift devices on an aircraft to increase the camber of the wing and reduce the stalling speed.On the Airbus A380, the first stage of lift device selection deploys the droop flaps (called droop noses by Airbus) and leading-edge slats located further out on the wing; with the main flaps starting to extend when the second stage is selected.
