Abstract: The invention relates to an aircraft sliding door comprising: a door leaf, which is slidable between a closed position and an open position in the opening and closing direction, respectively, and has a door top part and a door bottom part, which are arranged in a pulled-out state in the closed position and in a pushed-together state in the open position; a guide rail; and a drive device having an electric motor for assisting the movement of the door leaf from the open position to the closed position, wherein the drive device has a spindle that is connected to the electric motor and is inclined with respect to the opening and closing direction such that the door leaf is automatically transferred into the open position along the spindle when the electric motor is in a de-energised state.

Abstract: The invention relates to a control surface element for an airplane, in particular a spoiler, comprising a composite fiber element that has a surface around which air flows, a mounting device for movably mounting the composite fiber element on a structural component, and a reinforcing structure for reinforcing the composite fiber element. The reinforcing structure comprises at least one reinforcing element which is integrally formed with the composite fiber element. The reinforcing structure comprises a primary reinforcing element which is designed to receive main loads and which is connected to at least one secondary reinforcing element that is designed to receive secondary loads. The composite fiber element comprises a recess for integrally forming the primary reinforcing element.
