Retraction of the trailing edge flaps also retracts the leading edge flaps and slats. As trailing edge flaps retract to the 5 degree position, the leading edge flap and slat control valve moves to the intermediate extend position. This retracts the leading edge slats to the intermediate extend position, while leading edge flaps remain fully extended. Further retraction of trailing edge flaps to the FLAP UP position closes the valve and retracts all leading edge flaps and slats.
(3)
The autoslat system automatically extends the leading edge slats from the intermediate extend position to the full extend position and back to the intermediate extend position. The autoslat computers are enabled during takeoff when the nose gear shock strut extends. If the AOA sensors indicate that the angle of attack is too great, the computers will activate the autoslat control valve. When the main gear lifts off, the angle of attack required for autoslat activation increases, in several seconds reaching a final value of approximately 5.8 degrees for the remainder of the flight.
(4)
When either autoslat control valve solenoid is activated, the valve ports hydraulic pressure from the intermediate slat extend pressure line to the full extend pressure line which fully extends the slats. When the AOA sensors indicate that the angle of attack has dropped below approximately 5.8 degrees, the valve solenoids are de-energized, pressure is removed from the full extend line, and the slats return to the intermediate extend position.

(1)
Operation of the autoslat system is automatic. No control functions are exercised.
