An aircraft spoiler 130 is moveable between a stowed configuration and a deployed configuration by means of a spoiler actuation apparatus 200. The spoiler actuation apparatus comprises a guide member 210, a rack 220 mounted on the guide member and slidable along a longitudinal axis of the guide member, and a gear 240 coupled to the rack, the gear arranged to move the spoiler in response to sliding of the rack. The rack is held at a first position when the spoiler is in the stowed configuration. An actuator moves the rack from the first position to a second position along the longitudinal axis. When the rack is at the second position, the rack is operable to accelerate relative to the guide member away from the second position by an aerodynamic force acting on the spoiler.
