The Gulfstream G500 and G550 are business jet aircraft produced by General Dynamics’ Gulfstream Aerospace unit, located in Savannah, Georgia. They are variants of the Gulfstream V.

The G500, a variant of the Gulfstream V, was launched in 2002 and certified by the FAA in 2003.[1] It was introduced into service in 2004. As a shorter range version of the G550, it has the same exterior appearance, as well as the PlaneView cockpit, but does not have EVS as standard equipment, although it is available as an option. It has a lower fuel capacity than the G550 for a range up to 5,800 nautical miles.

The G550 was released to the market in 2003, and has increased performance. Range is increased to 6,750 nautical miles (12,500 km), mostly due to reductions in aerodynamic drag. The Gulfstream 550 is the longest range business jet in the world. Additionally, this aircraft has a “PlaneView” cockpit (which consists of 4 Honeywell DU-1310 EFIS screens, and a Gulfstream-designed cursor control system), and an “Enhanced Vision System” (EVS), an infrared camera that displays an image of the view in front of the camera on a head up display. EVS permits the aircraft to land in lower-visibility instrument meteorological conditions than a non-EVS-equipped aircraft. This aircraft may be distinguished from the legacy Gulfstream V by a seventh passenger window on both sides of the aircraft, and by the square outflow valve on the aircraft right side as compared to the circular one on the GV. More than 124 Gulfstream G550 aircraft have been produced.

The Gulfstream 550 competes against the Airbus Corporate Jet, Boeing Business Jet, and the Bombardier Global Express.
