Patent AT-E401239-T1: [Translated] SHEET FOR AN AIRCRAFT AND METHODS THEREOF

Aircraft leading edge apparatuses and corresponding methods are disclosed. In one embodiment, an aircraft system includes an airfoil (210) with a leading edge device (220) that is movable among a retracted position, at least one first extended position, and a second extended position. A first actuator (260) can be operatively coupled to the leading edge device to move a flow surface (222) between the retracted and the at least one first extended position. A second actuator (270) can be operatively coupled to the leading edge device to move the flow surface between the at least one first extended position and the second extended position. <IMAGE>
