An aircraft wing assembly, comprising a wing having a fixed leading edge, a slat mounted upon a slat deployment mechanism for moving the slat between a retracted position and an extended position with respect to the fixed leading edge, the fixed leading edge having an aperture to accommodate the slat deployment mechanism, and a closing plate mounted off the slat deployment mechanism for closing a gap between a lower trailing edge of the slat and a lower edge of the aperture when the slat is retracted. The closing plate can include a first portion and a second portion, and a hinge connecting the first and the second portions. The closing plate can include a plurality of integrally formed spacer elements for positioning the closing plate with respect to the slat deployment mechanism. Also, a method of removing an access panel in an aircraft wing assembly.

1. An aircraft wing assembly, comprising a wing having a fixed leading edge, a slat mounted upon a slat deployment mechanism for moving the slat between a retracted position and an extended position with respect to the fixed leading edge, the fixed leading edge having an aperture to accommodate the slat deployment mechanism, and a closing plate mounted off the slat deployment mechanism for closing a gap between a lower trailing edge of the slat and a lower edge of the aperture when the slat is retracted, wherein the closing plate includes a first portion and a second portion, and further comprising a hinge pivotally connecting the first and the second portions. 2. An aircraft wing assembly according to claim 1, wherein the hinge is a mechanical hinge or a strip of increased flexibility within the closing plate construction. 3. An aircraft wing assembly according to claim 1, wherein the fixed leading edge includes a removable access panel adjacent the aperture, and a portion of the closing plate overlaps the access panel when the slat is retracted. 4. An aircraft wing assembly according to claim 1, further comprising a plurality of spacer elements for positioning the closing plate with respect to the slat deployment mechanism. 5. An aircraft wing assembly according to claim 1, wherein the closing plate is mounted off the slat deployment mechanism by a plurality of fasteners, and at least some of the plurality of fasteners are quick release fasteners. 6. An aircraft wing assembly according to claim 1, wherein the closing plate includes an elastomeric material, preferably silicone. 7. An aircraft wing assembly according to claim 1, wherein the closing plate includes one or more rigid inserts. 8. An aircraft wing assembly according to claim 6, wherein the insert(s) is/are moulded within the elastomeric material. 9. An aircraft wing assembly according to claim 7, wherein the insert is a plate. 10. An aircraft wing assembly according to claim 1, wherein the closing plate comprises a layer resistant to environmental conditions. 11. An aircraft wing assembly according to claim 10, wherein the layer is provided on an outer surface of the closing plate. 12. An aircraft wing assembly according to claim 1, wherein the closing plate has a low surface friction coating. 13. An aircraft wing assembly according to claim 12, wherein the coating is provided on an inner surface of the closing plate. 14. An aircraft wing assembly according to claim 13, wherein the coating is provided around only a periphery of the inner surface. 15. An aircraft wing assembly according to claim 1, wherein the closing plate is sufficiently flexible to seal against the slat and/or the fixed leading edge when the slat is retracted. 16. An aircraft comprising an aircraft wing assembly according to claim 1. 17. A method of removing an access panel in an aircraft wing assembly, the wing assembly comprising a wing having a fixed leading edge, a slat mounted upon a slat deployment mechanism for moving the slat between a retracted position and an extended position with respect to the fixed leading edge, the fixed leading edge having an aperture to accommodate the slat deployment mechanism, and a closing plate mounted off the slat deployment mechanism for closing a gap between a lower trailing edge of the slat and a lower edge of the aperture when the slat is retracted, wherein the fixed leading edge includes a removable access panel adjacent the aperture, and a portion of the closing plate overlaps the access panel when the slat is retracted; and, with the slat retracted performing the steps of: releasing the overlapping portion of the closing plate from the slat deployment mechanism;rotating the normally overlapping portion of the closing plate about a hinge formed in the closing plate, whilst the remainder of the closing plate remains attached to the slat deployment mechanism; andremoving the access panel once the closing plate is hinged clear of the access panel. 18. An aircraft wing assembly, comprising: a wing having a fixed leading edge, a slat mounted upon a slat deployment mechanism for moving the slat between a retracted position and an extended position with respect to the fixed leading edge, the fixed leading edge having an aperture to accommodate the slat deployment mechanism, and a closing plate mounted off the slat deployment mechanism for closing a gap between a lower trailing edge of the slat and a lower edge of the aperture when the slat is retracted, wherein the closing plate includes a first portion and a second portion, and a hinge connecting the first and the second portions, wherein the normally overlapping portion of the closing plate is arranged to be rotated about the hinge to permit removal/installation of the access panel, and wherein the fixed leading edge includes a removable access panel adjacent the aperture, and a portion of the closing plate overlaps the access panel when the slat is retracted. 19. An aircraft wing assembly according to claim 4, wherein spacer elements are integrally formed with the closing plate. 20. An aircraft wing assembly according to claim 4, wherein the spacer elements are deformable compression pads. 21. An aircraft wing assembly according to claim 4, wherein the closing plate includes four spacer elements.
