Autoslats
At flap positions 1, 2 and 5 an autoslat function is available that moves the LE slats to full
extended if the airplane approaches a stall condition. The autoslat system is designed to
enhance airplane stall characteristics at high angles of attack during takeoff or approach to
landing. When TE flaps 1 through 5 are selected, the LE slats are in the extend position. As
the airplane approaches the stall angle, the slats automatically drive to the full extended
position prior to stick shaker activation. The slats return to the extend position when the
pitch angle is sufficiently reduced below the stall critical attitude.
