Aircraft synthetic-vision systems (SVS), when combined with GPS, gyros, accelerometers and terrain and obstacle databases, provide pilots with a colorful, animated depiction of the world outside the cockpit, matching what they would see looking through the windshield on a clear day. But to really see what is outside in dark or low-visibility conditions, you need an infrared (IR) camera. When you add forward-looking IR to SVS, you get a heat-referenced, real-world view along with a 3-D, database-derived and geo-referenced virtual view. Together they are called enhanced or combined SVS.
The Bombardier Enhanced Vision System in the Challenger 605 received EASA certification last week. This system, which is already certified by Transport Canada and the FAA, consists of a head-up display and a forward-looking infrared camera, increasing situational awareness by providing an overlay image of the outside environment–including terrain, runway, other aircraft and animals–on the HUD, as well as on the copilot’s multifunction display. This capability further increases safety during taxiing, takeoff and approach in low-visibility conditions, Bombardier said.
Rockwell Collins received the top honor–a gold award in the safety category–from the Edison Awards in recognition of the company’s development of synthetic vision on a head-up display (HUD). The awards program is conducted by Edison Universe, which fosters future innovators. The awards were named after prolific inventor Thomas Edison.
Honeywell already delivers synthetic vision for business aircraft under the brand name SmartView, a system that uses the terrain database of the company’s renowned Enhanced Ground Proximity Warning System (EGPWS), merged with head-up display (HUD) symbology. It then presents the SVS graphics on an aircraft’s primary flight displays (PFD).
Honeywell, which provides SmartView synthetic-vision systems (SVS) for Gulfstream business jets with PlaneView avionics, Falcon jets with EASy II flight decks and Pilatus PC-12 NG turboprops with Apex cockpits, is far along in its development of a combined vision system (CVS), which marries forward-looking infrared to SVS, for helicopters.
The Rockwell Collins HGS Flight app for the iPad may seem like a game, but spend enough time with it and you’ll soon come to appreciate the benefits of a head-up display (HUD) and learn about HUD symbology and operation.
There is a new way to learn how to fly with a head-up display (HUD) without booking time in an expensive simulator or trying to learn in the airplane. FlyRealHUDs.com has developed an inexpensive HUD simulator plug-in that runs on the X-Plane personal-computer flight simulator program. The FlyRealHUDs (FRH) plug-in replicates the symbology and flight dynamics of real HUDs and comes in two configurations, for business jets and airliners. (Full disclosure: I was a beta tester of the FRH HUD before its release in late October.)

Rockwell Collins China managing director Ron Ho believes business for aircraft head-up displays (HUD) in China will soon be looking up. “We have been working with the Civil Aviation Administration of China (CAAC) for the past 10 years on the HUD project,” he explained.
The FAA issued draft Advisory Circular 25-11A, which provides advice on how head-up displays can be designed, tested and installed in Part 25 transport-category airplanes. However, the AC’s new HUD content, which is found in Appendix 6, clearly states that it is not a source of means of compliance for display of enhanced vision or synthetic vision system imagery on HUDs. The new Appendix 7 of the updated AC covers guidance for standards that should be considered for display of weather information on avionics.
