Abstract:
An apparatus for controlling the motion of an aircraft, comprising first and second pilot controllers each of which moves in the same degree of freedom, is directly operable by a pilot and is arranged to independently control motion of in aircraft about at least one axis thereof, and a coupling assembly coupling said first and second controllers to cause substantially identical and simultaneous motion of said controllers by varying a fluid distribution, wherein said coupling assembly comprises:a first chamber including a first bellows for enabling a fluid in said first chamber to be displaced, said first bellows being coupled to said first controller; a second chamber including a second bellows for enabling a fluid in said second chamber to be displaced, said second bellows being coupled to said second controller, and a conduit for transporting fluid between said first and second chambers in response to motion of a said bellows.
