PARIS--(BUSINESS WIRE)--June 16, 2003

A Collins Pro Line 21 advanced avionics system received U.S. Federal Aviation Administration and Transport Canada certification onboard the new Bombardier Challenger 300 super-midsize aircraft. Rockwell Collins, as the aircraft's avionics system integrator, was responsible for all aspects of the avionics program, from design through certification.

The flight deck features four 12- by 10-inch liquid crystal flight displays, consolidated control panels and more efficient operation, and integrates a number of advanced technologies, including TCAS II and terrain awareness warning systems as standard equipment. Situational awareness is further enhanced through options such as turbulence-detection weather radar and 3-D Flight Management System navigation maps.

The Bombardier Challenger 300 is the first new aircraft platform to be equipped with Collins Pro Line 21 CNS. The new sensors are significantly smaller and lighter than existing sensors, conserving space for future avionics technology insertions.

The Pro Line 21 CNS sensors support the transition from voice to data communications. The Collins VHF-4000 Voice/Data Transceiver accommodates VHF Data Link (VDL) Mode 2, with growth to support VDL Mode 3 and Mode 4, enabling new capabilities in the flight deck including automated digital messaging, automatic flight plan loading and the transmission of graphical weather information. A high-speed digital interface is used to convey both data and audio, which is managed and consolidated by the Collins RIU-4000 Radio Interface Unit.

Collins NAV-4000 Navigation Receiver combines VOR/ILS and ADF functions into a single unit reducing size and weight. The Collins GPS-4000 Global Positioning System sensor is designed to accommodate upgrades to support future navigation enhancements and precision approach capability. The Collins TDR-94 and TDR-94D Mode S Transponders satisfy all current and planned surveillance requirements, including Mode S Elementary and Enhanced Surveillance to meet the upcoming requirement for operations in European airspace.

The avionics suite includes the Collins Engine Indication and Crew Alerting System (EICAS) to monitor, analyze and display performance of aircraft engines and other on-board systems. Linkage of EICAS monitoring capabilities to the aircraft's maintenance diagnostic computer permits aircraft systems performance and maintenance data to be sorted, logged and analyzed, enhancing operations and simplifying maintenance.
