Posted by John McHaleCEDAR RAPIDS, Iowa , 3 May 2010. Air China Limited selected Rockwell Collins to provide avionics systems for 20 new Airbus A330 aircraft. Equipment includes Rockwell Collins' MultiScan hazard detection system, GLU-925 Multi-Mode Receiver (MMR), and a suite of advanced sensors. Deliveries are scheduled to start in 2011. The MultiScan system is a weather radar that analyzes and determines actual weather hazards, not simply atmospheric moisture content, to provide flight crews more accurate weather returns. The system is an automatic, hands-free airborne weather radar that reduces pilot workload and enhances safety and passenger comfort by minimizing unexpected turbulence encounters, and provides optimal clutter-free weather displays. The advanced GLU-925 Multi-Mode Receiver is the first MMR certified for precision landing using either Global Navigation Satellite Systems (GNSS) or Instrument Landing Systems (ILS). The GLU-925 is the primary navigation sensor for all phases of flight, including the stringent Required Navigation Performance (RNP) requirement of 0.1 nm. Other products chosen by Air China include: ADF-900 Automatic Direction Finder, DME-900 Distance Measuring Equipment, HFS-900D High Frequency Communication System, CPL-920D Coupling Unit, LRA-900 Low-range Radio Altimeter, RAA-700 Radio Altimeter Antenna, VHF-2100 Very High Frequency Transceiver, VOR-900 Marker Beacon Receiver, and the GNA-925 Global Navigation Antenna.
