(Paris International Air Show - June 13, 2005) CMC Electronics Inc. has been selected by Sikorsky Aircraft Corp. to supply its latest-generation open architecture Aircraft Management System (AMS) for the Canadian Forces H-92 Cyclone to be supplied by Sikorsky for the Canadian Maritime Helicopter Project (MHP). The planned fleet of 28 H-92 multi-role helicopters will be equipped with two CMC Electronics Aircraft Management Systems per aircraft.

The CMC Electronics' Aircraft Management System known as the CMA-2082MH incorporates significant new architectural and processing advances. The open architecture and compact power PC chip-set will provide the Canadian H-92 Cyclone with the substantial processing power required for combat missions. The PCI open system architecture will allow Sikorsky to easily implement full Flight Management System and communication management capability as well as act as a controller for the search and weather radar, the IFF, the self-defence and sonobuoy processing systems, and the stores and armament management system. The CMA-2082MH will also be integrated with the General Dynamics Canada mission system and the Rockwell-Collins multi-function displays aboard the H-92 Cyclone.
