SLAT ASSEMBLY

摘要

A method of operating an aircraft wing assembly, the assembly comprising a main wing element (1) with a leading edge (2); a slat (3) on the leading edge of the main wing element; and a seal member (4). The assembly is placed in a first configuration during take off in which the slat is in a deployed position with a slot between the slat and the main wing element, and the seal member is in a deployed position in which it seals the slot (23). During cruise both the slat and the seal member are retracted. During landing the slat is deployed fully with a slot (25) between the slat and the main wing element, but the seal member is kept in its retracted position so that the slot remains open.
