Rudder pedal
input control devices (100, 200, 300, 400A, 400B, 500, 600) are described that utilize a straight-line mechanism and rotary joints to achieve straight line motion in a compact volume. The devices include bar linkages (106, 108, 206, 208, 306, 308, 506, 606) that translate forward motion of a pedal (110, 112, 210, 212, 310, 312, 510, 610) into a rotary motion of a common shaft (102, 202, 302, 502, 602), such that forward motion of one pedal (110, 112, 210, 212, 310, 312, 510, 610) causes the other pedal (110, 112, 210, 212, 310, 312, 510, 610) to retract while allowing for
yaw motion control of the aircraft.
