simple slot There are many combinations of slots and flaps available for use on airplanes For example, the arrangement on a Boeing 737 airplane uses a leading-edge slat

Fixed-Wing Aircraft Numerical Investigation of Leading Edge Blowing and Optimization of the Slot Geometry for a Circulation Control Airfoil

fixed slot leading edge At high angles of attack, slots allow higher pressure air to flow from the underside of the wing's leading edge into the air moving over the top

Some STOL aircraft in this category are characterized by a fixed slot at the leading edge penalizing parasite drag and flight speed in cruise
