 The Cheyenne had a two @-@ seat tandem cockpit featuring an advanced navigation and fire control suite . The tandem seating placed the pilot in the rear seat , and the gunner in the front seat . An unusual feature of the gunner 's station was that the entire seat , sighting system , and firing controls rotated to keep the gunner facing the same direction as the gun turret being controlled . The gun @-@ sight afforded the gunner direct viewing from the turret by way of a periscope sight . The pilot had a helmet mounted sight system for aiming weapons .
