Rockwell Collins' advanced Pro Line 21 CNS radio sensor package has received supplemental type certification on a Challenger 601. Collins Pro Line 21 CNS provides operators of current aircraft, as well as new-production business and regional aircraft, the technology to meet new regulatory and operating requirements. Additionally, Collins CNS radios are standard on the Bombardier Challenger 300, Cessna CJ3 and Gulfstream G150 aircraft. Certification of the Challenger 300 is expected this summer.

Collins 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.

The 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 new sensors are significantly smaller and lighter than existing sensors, conserving space for future avionics technology insertions. They may be installed either as stand-alone units or as an integrated package. Operational upgrades will be implemented through software changes.
