An aircraft braking system (fig.10,200) has an airbrake 132 which is moveable between a retracted position, where it does not project from the aircraft’s fuselage 110, to a deployed position where the airbrake projects from a lower surface 112 of the fuselage, generating drag on the aircraft when moving in a forward direction when landing gear 130 is extended. Also claimed is a controller (fig.11,300) suitable for controlling an aircraft braking system to, and a method of, selectively generating drag to slow an aircraft involving the step of causing the airbrake to be deployed from the lower fuselage surface when a certain criteria is met, such as: aircraft speed in a certain range or below a minimum; the aircraft is on the ground; a braking command has been issued; or landing gear is extended. Preferably the airbrake is rotated between positions, there may be multiple airbrakes (fig.10,136) on an aircraft connected by a linkage, and an actuator (fig.10,204) moves the linkage (fig.10,210) causing all airbrakes to move. Protective panels ((fig.10,206) may be provided which block part of an aperture in the fuselage from which the airbrake extends, the panel may be formed from a number of linkage connected sub-panels.
