The increased visibility from GAViS provides pilots better reference points, which improves pilots’ situational awareness and allows them to respond more effectively to changing flight conditions.
Enhanced Vision System
Picture this approach: A large-cabin business jet is about to land during a rainy night at Portugal’s Madeira Airport―one of the most daunting runways in the world with jagged mountains on one side, ocean on the other and constantly shifting crosswinds in play.
What makes this a picture-perfect landing? The aircraft is a Gulfstream and comes equipped with the Enhanced Vision System (EVS).
Gulfstream in 2001 became the first civilian aircraft manufacturer to develop and earn certification for EVS on its flight decks. Gulfstream EVS is surrounded by an artificial cooling system that better enables the infrared receivers to detect the slightest variations in infrared light emitted from runway lights, airports and even vehicles on the ground.
The vision system is considered such a navigational advantage that the Federal Aviation Administration in a Part 91 rule change allows an EVS-trained pilot to descend to 100 feet/30 meters―lower than typical decision height―until a visual reference is established. That’s an advantage that reduces go arounds, putting aircraft and passengers on the ground faster and reducing the amount of fuel expended.
With EVS, a nose-mounted infrared camera sends heightened images into the cockpit. Even at night, in light fog or rain, the advanced technology of a Gulfstream EVS reveals taxiways, runway markings, adjacent highways and surrounding terrain, making landings more certain and safer.
Working in tandem with the head-up display (HUD), EVS transmits images to the transparent screen in the pilot’s forward field of vision, creating a seamless, uninterrupted flow of information that increases a pilot’s situational awareness and response. That’s another benefit of Gulfstream EVS. Some after-market vision systems can’t superimpose EVS images on the HUD.
Use of the EVS is additionally guaranteed by the outer window covering for the unit. Rather than glass or plastic, Gulfstream EVS is equipped with a heatable sapphire window. In rainy or icy conditions, the heated sapphire window assures that the EVS unit has a clear view to detect infrared images.
EVS with HUD is a standard feature in the Gulfstream G650ER, the Gulfstream G650, Gulfstream G550 and Gulfstream G450, and can be installed as an option in the Gulfstream G280. The Gulfstream G150 offers improved situational awareness with a heads-down EVS option.
Experience Product Enhancements
Maintenance management and aircraft availability get an additional boost with the Gulfstream-created PlaneConnect program, an onboard, in-flight computer program that monitors aircraft systems and emails maintenance information to operators’ technicians.
The world is not flat. So why should a pilot’s cockpit display only be two-dimensional? Seeing accurate terrain representation rather than a simple color-coded representation is a unique safety feature of the Gulfstream Synthetic Vision-Primary Flight Display (SV-PFD).
The Gulfstream GIV and Gulfstream GV cockpits leap forward in avionics capability with a PlaneDeck retrofit, which replaces the original Cathode Ray Tube (CRT) primary flight displays with sharper, more vivid Liquid Crystal Display (LCD).
