Rockwell Collins Flight Dynamics and Bombardier Aerospace have received US Federal Aviation Administration supplemental type certification for the Challenger 604 business jet's head-up guidance system (HGS).

The system is approved for weather conditions down to Category II approach minima of 100ft (30m) decision height and 370m runway visual range. It is based on the HGS used in the Bombardier Canadair Regional Jet.
