Utilization of a Commercial Instrument for the CH-46 Helicopter

Jack Jankovitz and Robert E. Mack

Abstract:	The CH-46 Helicopter is being upgraded with GPS navigation capability. The navigation system will‘be compliant with a document known as the Chief of Naval Operations (CNO) GPS Integration Guidance. This document (presently in draft stage) affects all Navy, Marine Corps and Coast Guard users who must fly in the National Airspace System (NAS) with GPS as a primary sensor for navigation data. It provides navigation requirements for those users (reference 1). As part of the navigation upgrade for the CH-46, two active matrix, color, liquid, crystal, flat panel displays are being added to the new navigation system, 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 CNO GPS Integration Guidance. A portion of the discussion involves the adaptation of the instruments to the unique requirements of the CH-46 helicopter.
