Rockwell Collins’ new HGS-5860 is the first head-up display (HUD) system with an LCD projector to be certified on a business jet–Dassault’s Falcon 7X. At EBACE yesterday, Rockwell Collins also announced that Gulfstream has selected the HGS-6000 HUD as standard equipment on the G450 and G550 and as an option on the remainder of its model line. Entry into service for Gulfstream’s version of the Rockwell Collins HUD is expected in 2009.
HUD systems typically use cathode-ray-tube projectors to beam light through collimator lens systems onto a combiner glass display mounted in front of the pilot. The LCD projector weighs much less than a CRT projector, according to a paper written by Rockwell Collins engineers and published by the International Society for Optical Engineering. In addition to brighter raster-type images and a digital interface, the authors wrote, “There are none of the high-voltage power supplies, analog/digital converters and deflection amplifiers found in CRT-drive systems, further improving cost and reliability.”
