ABSTRACT:
An aircraft wing leading arrangement includes a forward slat (10) movable between a stowed position and a deployed position in which a slot (13) is revealed. To prevent undesirable flow disturbances in the slot (13), a shutter device is provided for the aperture (22) in the leading edge through which the slat actuator mechanism (14) protrudes in the deployed position. This shutter device consists of a sprung (38) panel (30) of flexible material pivotally movable between aperture-blocking and aperture-unblocking positions.
