Horizon Air has been approved by the FAA to fly single-engine
Category III approaches in the Bombardier Q400, using Rockwell
Collins Flight Dynamics' HGS-4200 head-up display system. This
gives Horizon's pilots a wider choice of alternates when weather
across the system is bad, because a Cat III runway can now be
a legal alternate in conditions down to 200-foot ceiling and 1,800-foot
visual range. Flight Dynamics HUDs are offered on other regional
jets and on all Dassault's wide-cabin business jets.
