1. an air passage in an aerofoil to direct air from the lower to the upper surface, esp the gap formed behind a slat
2. a vertical opening between the leech of a foresail and a mast or the luff of another sail through which air spills from one against the other to impart forward motion

An air gap between a wing and the length of a slat or certain other auxiliary airfoils, the gap providing space for airflow or room for the auxiliary airfoil to be depressed in such a manner as to make for smooth air passage on the surface.
Any of certain narrow apertures made through a wing to improve aerodynamic characteristics.
A punched-out area of a hand-sorted card to connect two or more guide holes; slots can be extended to the outside edge with notches.
A narrow, vertical opening.
One of the conductor-holding grooves in the face of the rotor or stator of an electric rotating machine.

i. Fixed openings near the leading edge of the wing. At higher angles of attack, air from below the wing is guided through the slots and discharged over the upper surface, tangential to the wing surface, thereby re-energizing the boundary layer allowing a higher critical angle of attack. Slots are located ahead of ailerons and thus help maintain aileron control at lower speeds and at high angles of attack.
ii. The gap between the wing and the hinged trailing-edge surface (flap, aileron) through which air flows attached across the movable upper surface.
iii. A block of time allocated to an airport user to perform an aircraft operation (takeoff and landing) or for using a specific facility.
iv. The physical aperture of a slot aerial. See slot aerial.
