The Pilot Seat Positioning Device has a frame which includes a base frame, a lower frame, and an upper frame and four vertical posts extending between the lower frame and the upper frame. Four pistons are located between the base frame. An upper journal is mounted on the upper frame. A lower journal is mounted on the lower frame. An outer ring is mounted to rotate on the upper journal and the lower journal by an upper motor and lower motor. A support ring is mounted to rotate on the outer ring and the support ring is located generally at right angles to the outer ring. The support ring has a support ring gear mounted on it. A support shroud covers the support ring gear. An upper support motor and a lower support motor are mounted on the support shroud. An upper support idler gear and a lower support idler are mounted on the support shroud. An inner ring is mounted to rotate in the outer ring within the support ring. An upper inner union and a lower inner union are mounted on opposite sides of the inner ring. The inner ring includes an inner ring gear mounted on the outer periphery of the inner ring and an inner shroud covering the inner ring and inner ring gear. An upper inner motor and an upper inner idler gear and a lower inner motor and a lower inner idler gear are mounted on the inner shroud. A seat platform extends across the inner ring and is mounted on the inner ring. A seat support member is located generally at right angles to the seat platform and in the same plane as the seat platform. The seat support member is mounted to rotate on the support ring. A pilot seat is mounted on the seat support member and across the support platform. A hydraulic system and an electrical system controls the flow of hydraulic fluid.
