The CH-46 helicopter is being upgraded with GPS navigation capability and improved radio communications capability. This paper describes the overall integration program which is known as the Communications/Navigation/Control System (CNCS) Integration Program. The CNCS utilizes a Flight Management System (FMS) called the Control Display and Navigation Unit (CDNU), which controls and manages the navigation and communications subsystems. The CDNU and the subsystems with which it interfaces are described. The CNCS navigation subsystem follows the guidance of the Chiefs of Naval Operations (CNO) GPS Integration Guidance (GIG); the GIG is also described in this paper. As part of the navigation upgrade for the CH-46, two active matrix, color, liquid, crystal, flat panel displays are being added to the CNCS, giving the CH-46 the distinction of being the first Marine helicopter to receive flat panel technology instruments for primary navigation. These instruments have been designed for use by commercial aircraft and, up to now, have never been used in military applications. This paper discusses the new display instruments and how the display instruments will satisfy the GIG.
