11/11/2007 - SAVANNAH , GA – In an aviation first, Gulfstream
Aerospace flew an experimental business jet using a synthetic
vision system and an enhanced vision system together. This dual
navigation capability comprises the three-dimensional terrain
images of Gulfstream’s Synthetic Vision-Primary Flight
Display (SV-PFD) and the forward-looking infrared (FLIR) images
of the Gulfstream Enhanced Vision System II (EVS II), which
is the company’s second generation enhanced vision system.
“The combination of EVS and 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 two systems were thoroughly evaluated during three days
of flight testing in September. Gulfstream Experimental Test
Pilots Tom Horne and Rick Gowthorp, along with Honeywell Experimental
Test Pilot Jary Engels, flew a G450 test aircraft a total of
18-1/2 hours during the three-day period.
Their journey began at Gulfstream’s headquarters in Savannah
on Sept. 5. They flew west, performing approaches at airports
in Wyoming, Idaho, Montana and Washington and evaluating both
EVS II and SV-PFD approach images in some of the most demanding
airport environments. On Sept. 6, they conducted another 10
approaches at various airports in Washington, Oregon, California,
Nevada, Arizona and Colorado.
On their final day, Sept. 7, they concentrated their approaches
in Colorado and New Mexico where the mountainous terrain can
prove challenging. In the more than 20 approaches performed,
the EVS II and SV-PFD images performed flawlessly.
According to Henne, Gulfstream EVS II confirms the validity
of all of the terrain and airport images projected on the SV-PFD.
While SV-PFD displays three-dimensional, color terrain images
that are derived from data stored in the Honeywell Enhanced
Ground Proximity Warning System (EGPWS), EVS 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
Gulfstream expects to certify its next generation EVS II later
this year. 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
Honeywell 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.
Gulfstream EVS was developed in cooperation with Kollsman,
Inc., which working with Gulfstream, continues to provide maintenance
and service support to operators of EVS-equipped aircraft.
In July 2006, Gulfstream announced it would be the first business-jet
manufacturer to offer synthetic vision technology for new and
existing aircraft. 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
terrrain, obstacles, runways and approaches at locations throughout
SV-PFD is on schedule for FAA certification by the end of the
year and is expected to be available to customers in the second
quarter of 2008.
