Abstract
To eliminate undesired movement of control members, e.g. throttle control levers, subjected to high fore-and-aft accelerations, a mechanism is proposed in which brake pads (229), (231) bearing on a control surface (220) forming part of the control member are connected by a pivoted lever arrangement (203) to a pendulum (200). Oscillations of the pendulum due for fore-and-aft `g` forces cause a proportional displacement of the lever arrangement (203) which in turn causes one or other of the brake pads (229, 231) to apply a correspondingly greater frictional force to the control surface (220).
