An actuator for an aircraft control surface, the actuator comprising: first, second and third movable elements, wherein the third movable element is in screw engagement with the first movable element with a first lead , wherein the third movable element is in screw engagement with the second movable element with a second lead, wherein the first lead is different from the second lead to provide a reduction ratio between the first and second movable elements; wherein a motor engaging component of the first, second and third movable elements and third movable element is connectable to a motor such that the motor rotates the first component in use, wherein an aircraft control surface engaging component of the first, second and third moveable elements is connectable to the aircraft control surface to move the aircraft control surface on rotation of the motor engaging component in use.

An aircraft control surface system 101 comprises a control surface 102 and an actuator device 200 for controlling movement of the control surface between a retracted configuration and a deployed configuration. The actuator device comprises an actuator arm 202 coupled to the control surface, a barrel 204, a piston 206 and a pumping apparatus 212. The actuator can perform a deployment operation in which a deploying force causes the control surface to move from the retracted configuration to the deployed configuration and the piston to move so as to cause an increase in the fluid pressure difference between forward 208 and rear 210 chambers of the barrel. The actuator can also perform a retraction operation in which the pumping apparatus causes fluid to flow into the forward chamber of the barrel to further increase the fluid pressure difference and drive the piston to move so that the control surface moves from the deployed configuration to the retracted configuration.

A high-speed frequency divider (100), a method for generating an output signal (110) proportional to an input signal (106) by a frequency division factor (102), and a phase-locked loop comprising a high-speed frequency divider (100) are provided. The high-speed frequency divider (100) comprises a reduced frequency clock, an asynchronous clock divider, and clock selection circuitry. The reduced frequency clock is generated by dividing an input signal (106) by a clock reduction factor (104). The asynchronous clock divider updates an initial programmed count in synchronization with the reduced frequency clock to generate a frequency divided signal. The initial programmed count is based on the frequency division factor and the clock reduction factor (104). Clock selection circuitry selects a phase of the reduced frequency clock based on a received selection signal. The output signal (110) is based on the frequency divided signal and the selected phase of the plurality of phases.
