L-1011 Flight Controls: Leading Edge Slats (27-8/9)




The L-1011 has a leading edge slats system with seven slat panels on each wing. Three inboard of the engine strut and four outboard. The Slats are driven by hydraulic motors called a slat power drive unit. The slats attach to torque tubes with ball screw actuators.


Above is an image of the wing chord with a conventional leading edge slat.
