During the ERA assembly held last month in Salzburg, Austria, Rockwell Collins announced FAA certification of its HGS 4200 head-up guidance system (HGS) for use on Bombardier’s CRJ700 and of the HGS 4100 for the Canadian airframer’s Dash 8Q-400. U.S. West Coast operator Horizon Air supported both certification programs. German CRJ700 operator Lufthansa CityLine and French regional Brit Air also chose the HGS 4200.
For the CRJ700, the HGS 4200 will allow Cat III approach and landing down to 600-ft RVR and lower-than-standard Cat I approaches down to 1,600 ft. The HGS 4100 will allow Q400 operators to benefit from the same RVR limits and make low-visibility takeoffs down to 300-ft RVR.
