The Flight Dynamics division of Rockwell Collins next year plans to introduce a synthetic-vision system (SVS) with its Head-Up Guidance System (HGS, aka HUD) for Bombardier’s Global Express. The SVS HGS will be part of Rockwell’s Pro Line Fusion flight deck in the newest Global Express, and will overlay the normal HGS guidance symbology with a computer-generated, correctly oriented picture of the terrain ahead.
