Gulfstream Aerospace - certified synthetic vision system

Gulfstream : 05 April, 2008  (New Product)
Gulfstream Aerospace, has become the first Part 25 Original Equipment Manufacturer (OEM) to have a synthetic vision system certified by the Federal Aviation Administration (FAA).
In the closing days of 2007 and early in 2008 the FAA not only certified the Gulfstream Synthetic Vision-Primary Flight Display (SV-PFD) system but also certified Gulfstream’s second generation Enhanced Vision System (EVS) II. The certifications are approved for applications on Gulfstream G350, G450, G500 and G550 business jet aircraft. As a result of these certifications, Gulfstream is also the first OEM to provide its customers with both enhanced and synthetic vision systems.

The Gulfstream SV-PFD displays three-dimensional, color terrain images that are derived from data stored in the Honeywell Enhanced Ground Proximity Warning System (EGPWS). The Gulfstream EVS II provides actual, real-time images detected by an infrared camera mounted to the nose of the aircraft and viewed by the pilot on the Head-Up Display (HUD). Additionally, the EVS II confirms the validity of all of the terrain and airport images projected on the SV-PFD.

'The combination of EVS with SV-PFD brings a whole new level of safety to the flight deck,“ said Pres Henne, senior vice president, programs, engineering and test, Gulfstream. “The effect of using both systems simultaneously provides an unmatched magnitude of pilot situational awareness and a flight path that is always visible, regardless of the conditions outside the cockpit window.”

The original Gulfstream EVS, which was first certified by the Federal Aviation Administration on Sept. 14, 2001, incorporates a specially designed forward-looking infrared (FLIR) camera that projects an infrared real-world image on the pilot’s Head-Up Display (HUD). On even the darkest of nights, pilots using EVS can clearly see a mountain range, a runway or any aircraft or vehicles on taxiways.

The new EVS II is 22 pounds lighter, has four times the computational power and four times the memory of the original EVS. New to EVS II is an improved maintenance interface within the Gulfstream PlaneView ® flight deck. The EVS II hardware components are produced by Kollsman Inc., a leading manufacturer of Avionics and electro-optic equipment.

SV-PFD is a dramatic enhancement to the Gulfstream PlaneView ® flight displays. It features a three-dimensional color image of terrain overlaid with the primary flight display instrument symbology, which are arranged on the screen to create a large view area for terrain. Combining previously certified terrain data from Honeywell’s EGPWS with obstacle data, and using a new state-of-the-art graphics processor, SV-PFD accurately depicts terrain, obstacles, runways and approaches at locations throughout the world. SV-PFD is expected to be available to customers in the second quarter of 2008.

'Achieving these two separate and distinct certifications is a credit to the teams from Gulfstream and from the Federal Aviation Administration,” said Henne. ”Whenever you are involved in certifying first-of-a-kind systems, it takes a tremendous amount of cooperation, trust and respect for the parties to work together to achieve something which has never been done before. My congratulations go to the many people involved in the time-consuming and demanding test-programs that led to these certifications.”

In addition to its activities in EVS and SV-PFD, Gulfstream is working closely with Rockwell Collins on HUD-II, a Head-up Guidance System (HGS) that presents critical flight information in the pilot’s forward field of view. Compatible with EVS-II and integrated with PlaneView, HUD-II features an all-digital display that allows the pilot to see an integrated display of flight information and an infrared image from EVS-II in almost all weather conditions, thereby enhancing situational awareness and improving touchdown precision. Modular in design, HUD-II uses liquid crystal display technology and a bright light-emitting diode (LED) backlight to display real-world images and flight symbols on the HUD Combiner.

'This is the first time we are developing an advanced Head-Up Display for our entire family of Gulfstream aircraft,” Henne commented. “This next generation HUD design will support development of other advanced vision technologies as they become available.”
