Leading Edge Slats
Slats are aerodynamic surfaces on the leading edge of the wings of fixed-wing aircraft which, when deployed, allow the wing to operate at a higher angle of attack. A higher coefficient of lift is produced as a result of angle of attack and speed, so by deploying slats an aircraft can fly at slower speeds, or take off and land in shorter distances. They are usually used while landing or performing maneuvers which take the aircraft close to the stall, but are usually retracted in normal flight to minimize drag.

Famous quotes containing the words leading and/or edge:
“Our leading men are not of much account and never have been, but the average of the people is immense, beyond all history. Sometimes I think in all departments, literature and art included, that will be the way our superiority will exhibit itself. We will not have great individuals or great leaders, but a great average bulk, unprecedentedly great.”
—Walt Whitman (1819–1892)
“They call back to us
from the gauzy edge of paradise,
good news, good news.”
—Anne Sexton (1928–1974)
