Leading Edge Slot

A leading edge slot is an aerodynamic feature of the wing of some aircraft to reduce the stall speed and promote good low-speed handling qualities. A leading edge slot is a span-wise gap in each wing, allowing air to flow from below the wing to its upper surface. In this manner they allow flight at higher angles of attack and thus reduce the stall speed.

Famous quotes containing the words leading, edge and/or slot:

    It is sometimes called the City of Magnificent Distances, but it might with greater propriety be termed the City of Magnificent Intentions.... Spacious avenues, that begin in nothing, and lead nowhere; streets, mile-long, that only want houses, roads, and inhabitants; public buildings that need but a public to be complete; and ornaments of great thoroughfares, which only lack great thoroughfares to ornament—are its leading features.
    Charles Dickens (1812–1870)

    Americans see history as a straight line and themselves standing at the cutting edge of it as representatives for all mankind. They believe in the future as if it were a religion; they believe that there is nothing they cannot accomplish, that solutions wait somewhere for all problems, like brides.
    Frances Fitzgerald (b. 1940)

    Some are able and humane men and some are low-grade individuals with the morals of a goat, the artistic integrity of a slot machine, and the manners of a floorwalker with delusions of grandeur.
    Raymond Chandler (1888–1959)
