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.
Although the Global Express and other future platforms will carry a digitized terrain database for TAWS, Flight Dynamics has opted for a proprietary database solely dedicated to its SVS. The SVS overlay will be pilot selectable, and Flight Dynamics will provide the capability to select either SVS or infrared enhanced-vision system (EVS) overlays on the HGS screen. The benefit of EVS is that while the SVS provides a full picture of the terrain ahead, it is based on a digitized terrain map of all previously surveyed fixed objects, whereas the infrared EVS shows non-surveyed objects such as an aircraft just taxiing onto the runway or a vehicle crossing the runway farther down.
