1. An aircraft wing comprising:
a wing structure;
a spoiler moveable relative to the wing structure between a stowed configuration and a deployed configuration; and
a spoiler actuation apparatus comprising:
a guide member;
a rack mounted on the guide member and slideable along a longitudinal axis of the guide member, wherein the rack is arranged to be held at a first position along the longitudinal axis when the spoiler is in the stowed configuration;
a gear coupled to the rack, the gear being arranged to move the spoiler relative to the wing structure in response to sliding of the rack, movement of the spoiler relative to the wing structure being substantially linear, defined within a plane defined by a height and a width of the spoiler; and
an actuator operable to move the rack from the first position to a second position along the longitudinal axis, wherein, 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, such that the spoiler moves from the stowed configuration to the deployed configuration.
