CMC Electronics Inc, has completed development and is in the final stages of integration of the CMA-2082D Control Display Unit (CDU) using ObjectAda/Raven for the Canadian Department of National Defense (DND) CP140 Maritime Patrol Aircraft.
The Canadian Department of National Defense (DND) operates a fleet of eighteen (18) CP140 Aurora aircraft as a long-range maritime patrol platform for surface and undersea surveillance roles. The aircraft design, which entered into service in 1980, is based on the United States Navy (USN) Model P-3C Update II Orion aircraft for the main airframe and engines, with mission avionics mostly based on the USN S-3A Viking mission avionics suite. The CP140 Aurora aircraft is undergoing a mid-life improvement program, referred to as the CP140 Aurora Incremental Modernization Project (AIMP), and includes a series of incremental upgrades over a ten-year period. CMC Electronics is the prime contractor for the Navigation and Flight Instruments Modernization Project (NFIMP) and developer of the CDU, which constitutes the integration and airworthiness certification of new NFI avionics equipment. The upgraded NFI System includes an Avionics Management System (AMS) consisting of four CDUs, two Embedded Global Positioning System (GPS)/Inertial Navigation System (INS) (EGI), Electronic Primary Flight Instruments (EFDS), Autopilot and Flight Director System (AFDS), Radar Altimeter and Altitude Warning System (RAAWS) and Traffic Collision Avoidance System (TCAS).
“CMC Electronics originally selected the ObjectAda/Raven product for use on the CMA-2082D AMS in 2000 following an extensive evaluation of Ada95 tool vendors. Aonix was selected for a variety of reasons including the usability of the tool set and the technical support that they were able to provide,” states Kevin Sanford, Software Project Lead, CP140 NFIMP Project for CMC Electronics. “The main discriminator, however, was the safety-critical domain experience of the company and their ability to meet the standards required for incorporation into a DO-178B software system.”
The CDU will control the avionics 1553 Data bus and act as a remote terminal on the Mission 1553 Data bus, under the control of a Mission Computer. The CDU will provide the Pilot, Co-pilot, Navigator-Communicator and Tactical-Navigator a means to control and monitor the operation of the two EGIs, provide area and terminal navigation solutions, and provide flight guidance generated by the CDU from an operator defined flight plan and the EGI outputs. The CDU navigation outputs will then be displayed on the EFDS and used as a steering source by the AFDS.
