Leading Edge and Leading Edge Devices ** ON A/C NOT FOR ALL
Leading Edge and Leading Edge Devices ** ON A/C NOT FOR ALL
The leading edge is forward of the front spar of the wing box, between the wing root and the wing tip. The leading edge has a fixed structure and five devices which are movable control surfaces.

The five movable devices are:
- Slat 1, inboard of the engine pylon (Ref. AMM D/O 57-42-00-00)
- Slats 2 thru 5, outboard of the engine pylon (Ref. AMM D/O 57-43-00-00), (Ref. AMM D/O 57-44-00-00), (Ref. AMM D/O 57-45-00-00) and (Ref. AMM D/O 57-46-00-00).
3. Description
A. Leading edge
The leading edge is a fixed structure of ribs and riblets to which nose skins are attached. The structure is strengthened by sub-spars. The five slats are connected, through the slat tracks, to the fixed structure.
These systems are also installed in the leading edge:

These systems are also installed in the leading edge:
- the drive mechanism for the slats (Ref. AMM D/O 27-84-00-00)
- the ducting for the engine bleed air (Ref. AMM D/O 36-11-00-00)
- electrical, hydraulic and pneumatic installations
- the environment protection system, between the wing root and RIB12 (Ref. AMM D/O 36-14-00-00)
- the ice protection system, which supplies Slats 3 thru 5 (Ref. AMM D/O 30-11-00-00).
B. Slats
The five slats (slat 1 thru slat 5) are wedge-shaped aluminum alloy structures. They are extended or retracted to give the correct lift to the aircraft. The drive system for the slats is electrically controlled. It uses hydraulic power to turn pinions installed in the fixed leading edge. The movement is transferred to the slats by racks attached to the slat tracks.
Each slat has a main rivetted structure of top and bottom skin panels and end ribs. The structure is strengthened by intermediate ribs, a girder and a top skin stringer. A trailing edge structure closes the aft edge of the slat and completes the aerodynamic profile. Slat track ribs give attachment points for the slat tracks.
